The difference between a construction vacuum cleaner and a household one. Principle of operation

A wall chaser is a tool for creating recesses in construction objects (walls, ceilings, floors) and materials (tiles, bricks, blocks). When working with a wall chaser, dust inevitably arises, which causes inconvenience even on the street, not to mention situations when you have to cut indoors. A vacuum cleaner will help to cope with this problem, but not an ordinary household one, which will simply break down from such loads, but a special, industrial one.

The best manufacturers of vacuum cleaners for wall chasers

A leader has long been identified in the market of washing and cleaning industrial tools. This is a German company KARCHER

(Kärcher).
It also produces special vacuum cleaners, and in a wide range. These are powerful, high-quality and reliable units designed for the highest loads. Bosch
,
Makita
and
Bort
are not far behind the leader . They also have the highest quality, and in terms of the variety of models they are all ahead of Karcher.

Moving to a more budget segment, it makes sense to pay attention to Russian manufacturers Caliber

,
Zubr
and
Soyuz
. It is worth noting here that they are only slightly inferior in quality to the market leaders, but significantly beat them in prices. Vacuum cleaners of these brands are cheaper initially, as are their repairs in case of breakdown.

What are the basic rules for working with a powerful vacuum cleaner?

As with other equipment, the main rule for using a powerful vacuum cleaner is to use it only for its intended purpose. You should first familiarize yourself with the list of types of garbage that can be removed using a particular model. And of course, you should not try to remove, for example, explosive substances with it. Not only is this guaranteed to cause damage, but it can also cause an accident.

Other standard safety rules when working with a powerful vacuum cleaner: do not immerse the body in water and try to protect it from splashes, do not leave the unit turned on unattended, do not touch the controls with wet hands, do not pinch or pull the power cord, securely fasten the dust container during operation and do not clean near flammable substances.

How to choose a vacuum cleaner for a wall chaser

The main criterion for choosing a suction device is its maximum compatibility with the wall chaser itself. For example, if you have a very powerful and fast wall chaser. Then the vacuum cleaner may simply not have time to suck up the resulting dust. There is no ideal formula, but experience shows that a ratio of 1:2 is quite sufficient. That is, if your wall chaser has a power of 2 kilowatts, then the vacuum cleaner should be no weaker than 1. However, almost all modern models have such characteristics. Finding a vacuum cleaner with less than a kilowatt of power is very difficult.

Air consumption, which is relevant when choosing a conventional vacuum cleaner, does not matter much here. The hose is connected directly to the wall chaser, that is, the capture of generated dust is already maximum. It is much more important to look at the convenience of a particular model:

• what container is used;
• are there any protective functions;
• how automatic cleaning works;
• How maneuverable and easy to transport the vacuum cleaner is.

And, of course, an important factor is the overall quality of the unit. There are a lot of manufacturers on the market, some well-known and some not so well-known. They all “guarantee” high quality and reliability, but in reality this is not always the case. To make the selection process easier for you, and without personal experience it is impossible to determine which model is better and which is worse, we have selected the most popular and sought-after models that have collected the largest number of reviews from real users.

Criteria for choosing a construction vacuum cleaner

A construction vacuum cleaner is a rather expensive tool, so it is important not to make a mistake in choosing it. You shouldn’t focus solely on a reasonable price and a familiar manufacturer’s name. To ensure that the new unit meets all your requirements and its purchase does not result in financial ruin for you, you should think through all the nuances in advance. Let's talk about the main parameters that you need to pay attention to.

Conditions for future use

To understand which construction vacuum cleaner to choose, whether you need a professional unit or a simpler household one can quite successfully cope with your tasks, whether you need a highly specialized tool, and if so, which one, try to answer a number of questions for yourself. How often is the vacuum cleaner expected to be used? Will it be used in a small home workshop or in a large production facility? Will you be collecting trash in a dry area or in an area that is regularly flooded with rain? Will it be enough to just collect dust or do you need to scrub the floors until they shine?

Do not forget that dust is different, and this aspect also needs to be taken into account. If the vacuum cleaner is intended to collect explosive substances, corrosive liquids or red-hot metal shavings, you will have to look for a specialized model. It should be mentioned here that all contaminants are divided into several classes according to the degree of their danger (and all manufacturers of vacuum cleaners must indicate what their equipment is designed for):

Power and performance

These two parameters are directly related to each other: the greater the power of the electric motor, the higher the performance of the vacuum cleaner and, as a result, its service life. The power consumption of construction vacuum cleaners is 1.0-1.4 kW, which allows them to pass through up to 50 liters of air per second. Professional models have even higher power (up to 7 kW), and this provides a performance of 60-100 l/sec. There are vacuum cleaners (for example, Makita-449) with two motors connected in parallel: depending on the situation, you can turn on either one (and save energy) or both (and increase productivity). The greater the power, the greater the safety margin of the construction vacuum cleaner, and this is important.

Vacuum degree

The vacuum created by the vacuum cleaner fan determines its suction strength. For construction vacuum cleaners, the value of this parameter ranges from 17 to 250 millibars. The better the vacuum, the heavier particles the vacuum cleaner can absorb. The degree of vacuum allows you to better assess the efficiency of the vacuum cleaner than power consumption.

Dust container volume

The volume of the dust collector of construction vacuum cleaners is usually 20-50 liters. If the volumes of garbage to be removed are small, you should not chase a large dust collector volume, because an increase in this parameter will lead to an increase in the size and weight of the unit. But for professional models, designed to work in large-scale production environments, the volume of the dust collector can reach 100 liters (this allows you to avoid frequent breaks during the work shift to empty it).

Vacuum cleaner body

The body of construction vacuum cleaners is made of impact-resistant materials - metal (aluminum, brass, stainless steel) or reinforced plastic. Often a bumper is installed around the perimeter to prevent the case from accidentally hitting a wall or other obstacle. Taking into account the large weight of construction vacuum cleaners (add here also the weight of the collected waste), when choosing, you need to pay close attention to the functionality and reliability of the wheels, as well as the handles for transportation. Of great importance, and you will see this during operation, are the length of the power cord and the length of the hose.

Additional options

Some models of vacuum cleaners have additional functions that are not necessary, but make the process of using the equipment easier (of course, the more functional the tool, the more expensive it is).

Let's look at the most important ones:

#1. Power socket. Power socket on the vacuum cleaner body for direct connection of power tools. By connecting the tool to such an outlet, the vacuum cleaner will turn on only when you activate the tool (press the button on the tool). After turning off the tool, the vacuum cleaner will turn off itself with a slight delay. This is a very convenient option, but when choosing a vacuum cleaner, look at the maximum possible power of the tool that you plan to connect to this outlet. Look at the power of the power tools that you are going to use with the vacuum cleaner and, when choosing a vacuum cleaner, focus on the tool with the highest power.

#2. Suction power regulator. This function is not available in all models, but in some cases of using a vacuum cleaner its presence is very convenient. With this function, you can change the draft, depending on the intensity of dust formation and the type of debris.

#3. Automatic filter cleaning function. During use of the vacuum cleaner, the main filter element becomes clogged and must be cleaned. To avoid having to disassemble the vacuum cleaner each time to clean the filter, some models are equipped with an automatic cleaning function. This system is installed above the filter and has a special valve that changes the direction of the air flow and blows the filter clear of blockages. The system can operate either in automatic mode and operate at the moment when the passage of air flow becomes difficult, or forcibly in manual mode. These vacuum cleaners are much more expensive, but if you intend to use the vacuum fairly intensively, the system is worth it.

#4. Adapters for connecting a vacuum cleaner hose to a tool dust removal system, as well as hose splitters that allow you to simultaneously connect two or more dust-generating devices.

#5. Light indication of the vacuum cleaner status, informing the user about a clogged hose or filter, about the dust container being full, etc.

#6. Motor overload protection (this function is especially important for industrial vacuum cleaners operating in harsh conditions of large-scale production).

Top 10. Wortex VC 2015-1 WS

Rating (2021): 3.75

18 reviews from resources were taken into account: Yandex.Market, Ozone

• Characteristics

  Average price: 5,800 rub.

• Country: China
• Power (W): 1300
• Vacuum (mbar): 190
• Air consumption (l/s): 30
• Dust capacity (l): 15
• Hose diameter (mm): 32

If you rarely use a wall chaser and the construction vacuum cleaner will be primarily used for another purpose, this model is worth paying attention to. This is an inexpensive Chinese unit with high performance, but the most ill-conceived system. Its power is 1500 watts and the vacuum is 190 mbar. In practice, this allows you to collect heavy suspended matter, but not for long, since the volume of the dust collector is only 15 liters. Moreover, it is fabric, so it is better to avoid collecting metal shavings. But here is the longest hose: 4 meters is the best indicator, which even Bosch and Karcher did not achieve.

Advantages and disadvantages

• Extra long hose
• Compact dimensions

• Very small dust container
• Fabric garbage bags
• Not the highest reliability

Design, principle of operation and methods of filtration of construction vacuum cleaners

Since this article is intended primarily for those who have never been the happy owner of such equipment, you should start ab ovo.

Every beginner starts by asking the question: “What is a construction vacuum cleaner and why can’t you use a regular household one instead?” Indeed, at first glance, these two electrical appliances do not differ in anything except their dimensions. However, although they have a similar structure and principle of operation, they are still designed to solve different problems, and this leaves its mark in the form of a number of design features.

So, the main difference between these two varieties of the same device is the object with which you have to “fight”. A household vacuum cleaner does a good job of removing ordinary light house dust, but if there are small pebbles in its path, they most likely will not end up in the dust collector. The situation will be even worse if someone tries to remove fine-grained construction dust using a household vacuum cleaner: the unit will “spit out” a significant part of it along with the air flow. Moreover, a lot of “undigested” dust will get into the electric motor, and this will most likely cause the latter to fail.

The industrial analogue is initially designed to collect construction dust and other construction and industrial waste. And the volumes of work in question are only within the power of him.

The distinctive features of construction vacuum cleaners include an impact-resistant body, an increased diameter of the hose, a large volume of the dust collector (and, as a consequence, significant dimensions and weight of the unit itself), a highly efficient multi-stage filtration system, high engine power and its ability to work without interruption for a long time.

Design and principle of operation

The principle of operation of a vacuum cleaner (in this case it does not matter whether it is industrial or household) is quite simple and is well known to all of us from our school physics course. The fan, driven by an electric motor, creates a strong vacuum inside the vacuum cleaner, which is the main driving force. The air, along with dust and other solids, flows through the hose into this low-pressure zone.

Most of the debris that gets inside the vacuum cleaner remains inside the dust collector; the remaining suspension of fine particles in the air is captured by additional filters. After passing through a multi-stage filtration system, the purified air is released through the outlet into the atmosphere.

The design of a construction vacuum cleaner using the example of BOSCH GAS 35 L SFC: 1. Electric motor with fan; 2. Incoming air flow with debris; 3. Container for garbage collection; 4. Filter cleaning system; 5. Filter cleaning system switch; 6. Filter for air purification.

A distinctive feature of construction vacuum cleaners is that dust and other contaminants can be collected both directly during work and after its completion (the first option, of course, is preferable):

#1. Suction from the working area. The vacuum cleaner hose is rigidly fixed as close as possible (as far as possible, so as not to interfere with work) to the workpiece being processed. This option is far from ideal, but it still allows you to reduce the concentration of dust in the air in the work area.

#2. Connect directly to the instrument. Many modern power tools are equipped with a dust extraction system - a special dust ejection pipe to which you can connect a vacuum cleaner hose. The amount of dust both in the air and on the workpiece itself will be minimized. The connected hose somewhat interferes with the operation of hand-held power tools, but for the sake of comfortable working conditions it is quite possible to put up with this small inconvenience.

#3. Cleaning the premises upon completion of work. Debris and dirt that have accumulated in the workplace can be removed after finishing work using a vacuum cleaner in the most traditional way.

Dust collectors and filters

Just like household vacuum cleaners, construction vacuum cleaners are divided according to the type of dust collector into bagless and bagless. The first type can be equipped, at the user’s request and in accordance with the manufacturer’s recommendations, with both reusable (fabric) and disposable (paper) bags. The group of bagless vacuum cleaners is also heterogeneous; two structurally different subgroups can be distinguished in it - cyclone (container) and aqua vacuum cleaners. Let's look at the features, advantages and disadvantages of all four types of dust collectors for construction vacuum cleaners.

Fabric bags

Reusable cloth bags are the ones most familiar to users as they continue to be the most common in regular household vacuum cleaners. After filling such a bag with debris and dust, it should be emptied, shaken out and put back in place. The number of cycles of use of such a dust collector is quite large, and therefore this option can be classified as low-budget.

For the manufacture of reusable bags for vacuum cleaners, satin was previously used - a cheap and at the same time quite strong and durable material. Today, satin is practically not used for these purposes; it has been replaced by synthetic fabrics. Recently, non-woven fabric has become increasingly popular as a material for the manufacture of reusable dust bags.

We have already mentioned the main advantage of reusable fabric bags - their low cost per filling cycle. But they also have a significant drawback, which the future owner of a construction vacuum cleaner must be aware of.

The fabric, while retaining relatively large particles well, easily allows fine-grained construction dust to pass through, which scatters over long distances with the flow of air coming out of the vacuum cleaner, evenly covering all surfaces. However, modern two-layer fabric based on non-woven fabric is capable of capturing even small particles several microns in size, thereby providing a good degree of cleaning.

Paper bags

Disposable paper bags in the literal sense of this layer are consumables: once filled, they, along with all their contents, are sent to a landfill. For the user, this means, on the one hand, ease of use, but on the other hand, additional expenses, and quite a lot.

The cost of one paper bag for a construction vacuum cleaner is $5-6, and one day you will realize that you have already spent more on consumables than on the equipment itself. In addition, disposable bags, like all consumables, tend to run out, and at the most inopportune moment, and it may turn out that you will be forced to quit work and start running around stores in search of bags for your model of vacuum cleaner.

However, for this fly in the ointment there is a whole barrel of honey. Paper dust collectors have excellent performance characteristics. They are significantly superior to their fabric counterparts in their ability to capture fine particles (up to 0.3 microns in size), which means that the air in the room will be clean, and you will have to clean and replace additional filters less often.

But you need to be careful with large construction waste: some large particles (broken glass, sharp pebbles, metal shavings) can easily tear the paper walls of the dust collector.

Container dust collector

In cyclone-type vacuum cleaners, all debris is collected under the influence of centrifugal force in a built-in reservoir. The disadvantages of units of this type include increased operating noise, which is a consequence of repeated collisions of solid particles trapped in the tank with its walls, and limited application. The latter is expressed in the fact that “cyclones” are only suitable for collecting large particles, water and moistened debris. Many cyclone models support bag handling. When using a bag, the main filter is much less clogged.

In addition to the dust collector, the filtration system of the vacuum cleaner includes one or more fine air filters. Such filters, which are disposable and reusable, are made of nylon (for fine dust), polyurethane (for sucked liquid) or a number of other, usually synthetic materials. Their main function is to capture fine suspended construction dust that is not retained in the main tank/bag.

The quality of room cleaning and the degree of engine wear depend on these filters. Just like the main dust collector, they need periodic cleaning to remove accumulated dirt. A filter clogged with dust is the main reason for reduced vacuum cleaner performance and increased load on the electric motor. If you decide to save on the vacuum cleaner itself and the quality of the main dust collector, be prepared for the fact that you will have to clean and replace filters more often.

Top 8. Bort BSS-1425-PowerPlus

Rating (2021): 4.03

57 reviews from resources were taken into account: Yandex.Market, Ozone, DNS

Reinforced body Vacuum cleaner with an all-metal body and a plastic base. The model is not afraid of accidental impacts and falls, which is very important in production or construction sites.

• Characteristics

  Average price: 7,500 rub.

• Country: Germany (manufactured in China)
• Power (W): 1400
• Vacuum (mbar): 210
• Air consumption (l/s): 42
• Dust container capacity (l): 25
• Hose diameter (mm): 32

A construction vacuum cleaner must not only be powerful, but also durable to withstand accidental impacts and falls. This model fully meets these requirements. Unlike other Bort models, this one has a completely metal body, as does the dust collection container. A wide platform with swivel wheels will prevent the unit from simply falling. BSS-1425-PowerPlus is an inexpensive but powerful construction vacuum cleaner that produces 1400 watts and 210 mBar of vacuum. Air consumption – 42 liters per second. The indicators are not record-breaking, but high enough to carry out the most complex work. In addition, a semi-automatic filter cleaning system has been installed, which greatly simplifies the work.

Advantages and disadvantages

• Self-cleaning system available
• Rugged housing
• Wide wheelbase

• Heavy model
• Inconveniently located socket

What should you pay attention to when choosing a powerful vacuum cleaner?

Traditionally, the choice of technical units is made according to their technical parameters, and powerful vacuum cleaners are no exception. Their main indicator is, of course, power: the higher it is, the more productive the equipment will be. For example, a model with a power of 1200 W will absorb up to 48 liters of air per minute, and a vacuum cleaner designed for 1500 W will absorb up to 70. Therefore, the choice in favor of one or another model should be made based on the volume of garbage you plan to remove .

Adjusting the suction power will not only help you adapt to a specific type of pollution, but also, if necessary, reduce the load on the network and energy consumption in general.

Dust class - determines what kind of contaminants you can work with. L - particles of soft wood, artificial stone, graphite; M - particles of hard wood, concrete, brick; H - dust containing carcinogenic substances, heavy metals, coal particles, mold. Also, many industrial models can suck up liquids and even oils.

The method of collecting garbage is in a container or in a bag.
Some models combine both methods. Of course, using a bagless vacuum cleaner is more economical in terms of purchasing consumables. However, some types of contaminants are easier and safer to dispose of only in bags. The price of a vacuum cleaner depends on all of the above parameters: the more powerful, functional and advanced it is, the more expensive it is. Of course, a professional is willing to pay a lot of money for high-quality equipment. It is also important that the vacuum cleaner is from a well-known brand with the possibility of service, the availability of consumables and a warranty period of several years. In this case, you can be sure that you are purchasing a unit for many years to come.

The most powerful vacuum cleaner The rated power of the vacuum cleaner is 1800 watts, which is 30% more than a similar model from competitors.

• Characteristics

  Average price: 6,500 rub.

• Country Russia
• Power (W): 1800
• Vacuum (mbar): 180
• Air consumption (l/s): 30
• Dust capacity (l): 30
• Hose diameter (mm): 35

Before us is a Russian-made vacuum cleaner that produces 1800 watts of power. With this indicator, it can easily cope with even the heaviest dust, for example, granite or marble. This is what this model is designed for. The vacuum is 180 mbar, which is not a record, as is the air consumption, but these parameters are fully compensated by the power of the unit. Of course, the vacuum cleaner will consume more energy, but nothing can be done about it. Also, the size of the dust collector of 30 liters and the container design allow it to be classified as heavy tools. No bags constantly tearing and scattering the collected garbage. This is a full-fledged construction vacuum cleaner without a hint of elegance in appearance.

Advantages and disadvantages

• High output power
• Metal dust container
• Reinforced durable housing

• Unattractive appearance
• Inconvenient transportation

What are the pros and cons of a powerful vacuum cleaner?

Among the main advantages of powerful vacuum cleaners are the following:

• fast cleaning of large rooms;
• reliable suction of debris and dust;
• high resource for daily work;
• improved filtration system.

In turn, the disadvantages of such units include:

• increased energy consumption due to the high power of the vacuum cleaner;
• high requirements for the electrical network (a weak network may not be able to handle such a load);
• As a rule, powerful vacuum cleaners have impressive dimensions;
• the price of such vacuum cleaners is several times higher than the cost of household models.

It is precisely because of all the above-mentioned disadvantages that the use of powerful vacuum cleaners for solving household problems becomes impractical, emphasizes FAN’s interlocutor.

Best value for money Construction vacuum cleaner from a top manufacturer at a very attractive price. A high-quality model with a high level of reliability.

• Characteristics

  Average price: 8,500 rub.

• Country: Germany
• Power (W): 1200
• Vacuum (mbar): 200
• Air consumption (l/s): 60
• Dust container capacity (l): 20
• Hose diameter (mm): 35

We have before us a unique case when a manufacturer underestimates the parameters of its product, rather than overestimating them. The annotation of the vacuum cleaner states that its class corresponds to light, that is, it is designed to collect exclusively light dust and mist. At the same time, the technical parameters tell us that it can easily cope even with granite chips and metal shavings. For 1.2 kilowatts of power there is 200 mBar of vacuum and 60 liters of air consumption. These are quite high values, which are not found in all models recommended for heavy work. Well, Metabo decided to play it safe and left a serious reserve of power. Given the brand's reputation, this deserves special respect.

Advantages and disadvantages

• Large power reserve
• High technical parameters
• Long cable
• A light weight

• Short hose
• Very thin fabric bags

Air purification filters

A construction vacuum cleaner must have a multi-stage air filtration system, including fine air filters. They are disposable and reusable. They are made from various materials:

• nylon (for the smallest particles);
• polyurethane (for liquids);
• other synthetic materials.

The purpose of the filter is to trap dust that comes out of the bag/reservoir along with the air. If the filter becomes clogged, it prevents air from escaping, which increases the load on the engine. In any case, you will have to clean the filters periodically. The frequency of this procedure depends on the quality of the main dust collector.

The most reliable vacuum cleaner A reliable model from a top brand. In reviews, buyers write a lot about the durability and unpretentiousness of the tool, even under high loads.

• Characteristics

  Average price: 14,600 rub.

• Country: Germany
• Power (W): 1250
• Vacuum (mbar): 200
• Air consumption (l/s): 35
• Dust capacity (l): 21
• Hose diameter (mm): 35

Bosch is one of the leaders in the tool market, and it constantly maintains its reputation. Here is a vacuum cleaner that customers called the most reliable and unpretentious. It works without interruption and even requires much less frequent filter changes. However, this is easy to explain. The Bosch vacuum cleaner used a special technology with which the tool cleans the filters itself, and you only need to change them from time to time. In terms of power indicators, everything is also in order. At 200 mbar of rarefaction there is almost 1.3 kilowatts. Despite the low air consumption of 35 liters, the vacuum cleaner can handle even heavy dust. And the presence of a humidifier significantly expands the scope of application of the tool.

Advantages and disadvantages

• Self-cleaning filters
• Compact form factor
• Long hose and wires
• High reliability

• Not the most attractive price tag
• No adapter for changing hose diameter

Best price The cheapest construction vacuum cleaner, costing about 15% less than the closest competitor with similar technical characteristics.

• Characteristics

  Average price: 5,500 rub.

• Country: Germany (manufactured in China)
• Power (W): 1300
• Vacuum (mbar): 160
• Air consumption (l/s): 29
• Dust container capacity (l): 25
• Hose diameter (mm): 32

Low price is the first thing that catches your eye when looking at this unit. But if you decide to choose it, keep in mind that the technical indicators here are quite low. The vacuum cleaner has 1300 watts of power, which is very impressive, but it only has 160 mbar of vacuum and 29 liters of air consumption. Simply put, if you use a vacuum cleaner on a wall chaser, you can only work with light materials. The tool will easily collect gypsum and aerated concrete dust, but it will not be able to cope with heavier suspensions. If this suits you, then you can save a lot of money. The BSS-1325 is an inexpensive wet/dry vacuum cleaner that is definitely worth a look.

Advantages and disadvantages

• Large dust bag
• Inexpensive option
• High motor power

• Low vacuum and air consumption
• Fabric dust bag

BOSCH GAS 12-25 PL

It is the blue Bosch series that our family likes the most. Vacuums both cement and wood dust. And it also copes with a dirty puddle. We have a lot of attachments; in fact, we use the main one and the slot one. Connects to construction equipment and works with it in tandem. As a housewife, I especially liked the strap that allows you to pull the vacuum cleaner behind you, saving the hose from breaking. The wheels don't scratch the floor, and ours even runs on clean floors. Before him, we had a Karcher construction vacuum cleaner, we sold it to buy a Bosch.

Makita VC2512L

A good Makita vacuum cleaner. Made “humanly”, normal equipment: three adapters for tools, three pieces of attachments, a long hose and cord, not stubs like in budget ones, a socket for connecting a 2.6 kW tool. I liked the vacuum cleaner, I bought it on Y.Market, everything was fine with the order and delivery, they called, warned me and then received an SMS, the courier delivered to the door, everything was packaged well, they opened it and checked it, paid by card, sent an electronic check to the mail, everything was good, the only one it's a guarantee. The courier threw up his hands, but it is clear that this is not his “merit”. Overall, I'm happy with the purchase and recommend it. The photo shows how it came in the box and its completeness.

BOSCH GAS 15 PS

Compact and powerful. I took it purely for an angle grinder to cut the grooves and it copes with its task perfectly. I was very upset that without a warranty card. Now if something happens to him, you will have to call the support service and ask for the coupon to be sent, wait two weeks until it arrives by mail, go to the post office, forget it and all this is a waste of time. It’s somehow not serious. I just don’t understand, you can’t immediately Place the warranty card with the product, just send it and that’s it.

KARCHER WD 3 P Premium

Roman Belov The vacuum cleaner has proven itself to be an unpretentious and reliable tool. The form factor of its body and components allows you to install, instead of the original cartridge filter, a filter element from a Muscovite, which costs 70-80 rubles. at the price of the original 900+ rubles, the vacuum cleaner is also compatible with homemade woven and non-woven bags, which allows you to save money on bags, which is very important considering their price! In general, I am completely satisfied with the vacuum cleaner, I use it exclusively for cleaning up construction waste when renovating apartments, in the garage, at the dacha, I recommend it to everyone! With bonuses from “thank you” it cost me 5400 rubles, which is good news)) link to the video of its upgrade.

Karcher WD 3 Premium

Simple as firewood, large filter, ability to suck up liquid, good selection of accessories, excellent power. There is no retractable wire, telescopic tube or other amenities that you are used to in home vacuum cleaners. However, having tried (and thrown out) about 7 different vacuum cleaners over the past 10-15 years, I realized that the Karcher is the iPhone of the vacuum cleaner world. It just works. Its simplicity and ease of use captivate you from the first minute. There is a video on YouTube where they remove the bag filter and replace the cartridge filter with an old T-shirt, and it still works and collects debris and construction dust into the container. I bought a vacuum cleaner for my home. If you have carpets, you will have to buy a set of brushes (2 pieces included) for your home. This is +2200 rubles. A car brush will cost another +900 rubles. Bags (5 pieces) cost ~650 rubles. But they are huge and 1 bag is enough for a long time when cleaning at home. The vacuum cleaner is not afraid of large and industrial debris. If necessary, it can be used in the entrance, on the porch, in the garage, during repairs. The water suction function is very convenient for dry cleaning. Spilled coffee on the sofa? I cleaned it with a sponge and detergent, vacuumed it, then with a sponge and water and vacuumed it again.

Metabo ASA 25 L PC

Quite a powerful device. Convenient to use. Quite a long corrugated pipe. There is a dust collection bag. Can be used without a bag. So far it evokes positive emotions. There is a socket for connecting an electrical appliance. In this case, the vacuum cleaner turns on when the device is turned on - this is very convenient. There are quite a lot of attachments. They are hung on the vacuum cleaner. The vacuum cleaner is very good in the house where there is space. Can be used in the workshop. You can also store it on the balcony, but there are a number of inconveniences. For example, all the attachments on the vacuum cleaner are hanging and you always touch them and they pop out. You can put attachments inside the vacuum cleaner, but this means that you must always remember about them so as not to throw them away with the trash. The wire should only be wound by hand.

KARCHER WD 2

Anyone who has used Karcher equipment, no matter what line and price category, be it the simplest wd2 for five thousand from the line of vacuum cleaners or a washing one for thirty, even for 60 thousand, will not highlight the advantages and I, having used it for more than 5 years, have any shortcomings (such as a cord It doesn’t wind up or the bags are expensive to renew and shaking out the old ones has become no longer interesting for a long time... etc., etc.) I consider it a feature. Karcher is power combined with reliability, durability and a consistently high level of cleaning... and it doesn’t matter whether construction dust is from concrete, or moisture is an accumulation of liquid, or simply clean the carpet or carpets so that they become like new in one or two passes. Alternatives were sought in in the price range up to 10 thousand rubles, there was no one. Karcher VD2 is like an ultimatum to all other vacuum cleaners, or rather, this is a model so that no one occupies the cheap price niche either - I got the impression that in use there are two more vacuum cleaners from other manufacturers, according to worthy reviews they were included once or twice. During the period of use, at the request of family and friends, “exactly like yours”, several more pieces were purchased, everyone is fine with it

Bort BSS-1220-Pro

I took it for garage carpentry. It’s an irreplaceable thing, I’m surprised how I ever managed without it. I recommend. The bag comes with guano, it’s better to immediately order normal disposable ones or sew a zipper into a fabric one (I saw such a life hack). It was tested on sawdust, fine concrete dust and pieces of concrete during gating. All is good. Just a disclaimer - I don’t use it professionally, so it doesn’t work all day on apartment renovations or in carpentry.

Makita VC2512L

Nikolay F. Good equipment, long hose, well-thought-out protection, you can easily work with a 2100w mortar cutter. Quality of material! In terms of price and quality ratio, this is the best option, taking into account the promotions and cashbacks, it cost just over 10k. I recommend! Yandex Market delivery gave me a pleasant experience in 12 hours and was delivered 200 km away. Ordered at 10 pm and arrived at 10 the next day! I recommend Makita, because after a week of studying the market, between three companies Metabo and Bosch, Makita came out the best of them

Leonid

Bort BSS-1218

Lightweight, plastic, which means it won’t rust outside in the workshop. Powerful. I took it for a home workshop, in principle it copes with metal and wood shavings. I connected it to the cross-cut saw and it also seemed to “suck”. I really enjoyed vacuuming the car! The carpet in the car is like new. Homemade bosch coped worse. The filter must be cleaned constantly. By the way, I remove the top part, put it on the chock, change it to “exhaust” and blow through this filter, it works fine. In general, for the money it’s a normal vacuum cleaner.
