How to choose and buy a construction vacuum cleaner

Recommendation points

The article will discuss various types of technical dust collectors. We will tell you about the main functions of modern construction vacuum cleaners. You will learn how to choose the right device, based on its technical characteristics, as well as about the average prices for vacuum cleaners.

How to choose and buy a construction vacuum cleaner

A vacuum cleaner is a familiar and necessary thing not only in everyday life, but also in production. The processing of metal and wood is invariably associated with the formation of dust, shavings and sawdust, which must be removed. This is especially true for work in residential or operated premises..

General characteristics

All models of non-household vacuum cleaners can be roughly divided into three categories:

  1. Technical or economic.Such units are also called “garage”. These are models of low and medium power (800-1200 W) with an average tank volume (10-15 liters). They have a minimum set of functions, as a rule, without parallel starting and adjustments. Designed for periodic use when servicing the territory – blowing leaves and snow, cleaning the car interior.
  2. Building.It has a compact engine of medium power (1000-1800 W) and a tank of 15-40 liters. The advanced design provides for the maximum number of adjustments, additional connections, indicators, relays, nozzles and various filters. It also provides an advanced overload protection system. Designed for working with industrial dust, small stones, shavings, sawdust and other working waste.
  3. Industrial.Motor from 1000 to 20,000 W. The stationary structure is calculated and assembled for a specific type of equipment.

The first of these types can be purchased for your own needs, as they say, “without looking.” With a small volume and periodic nature of work, even the most inexpensive model, suitable in terms of parameters and a set of functions, will serve for a long time. The latter type does not apply to private construction and economy. Of greatest interest is the class of construction vacuum cleaners, which has many nuances..

Possibilities of a construction vacuum cleaner (SP)

Speaking about the set of functions and operations of the joint venture, it should be noted that the rating includes quality products of the “professional” and “semi-professional” class, and not their household counterparts. Any tool engaged in a permanent job has the same requirements:

  • reliability (reliability);
  • convenience (quick change of the tool, switching, adjustment);
  • light weight and compactness.


The joint venture is no exception in this case, so some functions that affect the price are not aimed at increasing operations, but at extending the “life” of the entire device.

Engine power

The electric motor in the construction of the construction vacuum cleaner is used to create the suction force. This parameter is divided into two indicators:

  1. Suction speed. For professional models 3000-5000 l / min.
  2. Vacuum (vacuum). The indicator should be in the range of 150-250 mbar or 20-40 kPa.

The engine is selected (by the manufacturer) depending on the tank, provided that the proper suction speed and vacuum are ensured.

Approximate ratio of power and volume of the tank for the joint venture

Power, W Tank volume, l
1000 15
1200 15-18
1500 20-25
1600 25-30
1800 35 and more

What to look for. For different manufacturers, these indicators may vary slightly. For example, a more powerful motor can stand on a smaller volume. Also check the filter system. It can be developed, multistage, which takes away part of the power.

Parallel connection

Outwardly, this function manifests itself in the form of a socket on the body or lid of the device. Its meaning is that when you connect any power tool to this outlet, the vacuum cleaner starts up with it. This is very convenient when working in residential areas, when you cannot dust and litter – all dust and shavings are immediately sent to the vacuum cleaner.


What to look for. Reasonable design – such a socket should be placed on the side of the case and have a rubberized (or rubber) cover. The socket, which is mounted in the cover, can easily be accidentally flooded with water or dirty. The outlet indicates the maximum power of the tool that can be paired with a vacuum cleaner.

Blowing out

This basic function is found on almost all construction vacuum cleaners. Just make sure it is on the model of your choice..

Possibility to install a “wet” filter

A vacuum cleaner capable of collecting not only dust, but also moisture, can perform twice as many operations as compared to a “dry” analogue. It collects any dirt, such as from wet cutting of stone or tiles. It can also be used to rinse and dry the surface by back blowing.


What to look for. The ability to collect moisture is specifically indicated. It is impossible to convert a “dry” vacuum cleaner into a “wet” one without interfering with the engine design (additional protection is needed).

A set of attachments and accessories

The number of operations of a modern construction vacuum cleaner depends on this list, the arsenal of which may include:

  1. Composite hose.
  2. Corner attachment.
  3. Crevice tool.
  4. Smooth surface (glass breaker).
  5. Brush head (large and small).
  6. Rotary floor brush.

The presence of other additional attachments is a definite plus to the functionality of the device.

What to look for. First of all, make sure that the pipe (hose) is collapsible and has the ability to build sections. Check if it is possible to purchase additional sections separately. The nozzles are contact parts, so make sure the quality of the plastic – it must be strong and not have a pungent smell. The plastic must be antistatic.

Protective functions

This set of features keeps the entire device healthy. The more similar parts there are in the design of the vacuum cleaner, the more it is protected from overloads and operator errors.

Smooth engine start

This protective function is aimed at conserving engine life. Reducing the amperage at start-up reduces impulse and wear on mechanical parts. According to statistics, devices with this function last 30% longer without breakdowns than without it.

Tank full indicator

Shows the degree of fullness of the container. Practice has shown that the light indicator is ineffective – they simply forget about it during operation and the dust collector is overloaded. Sometimes you can find models with a sound signal, which is not always perceived correctly by an inexperienced operator. The most reliable option is a conventional trip relay. The tank fills up, the thrust weakens and the relay cuts off the power.

Automatic vibration cleaning (only for “dry” filters)

An extremely useful tool for ongoing work. A special “ratchet” constantly knocks dust off the filter, thereby clearing the path for air and increasing the filter life. Provides effective implementation of suction and stable operation of the vacuum cleaner. Models with this function are labeled AFC (Automatic Filter Clean).

Power Mode Switching (Power Down)

Usually the professional series has only two modes of operation – full and reduced. The second is used for wet, final and household cleaning. A thin superstructure in the form of a dimmer (rheostat) did not justify itself.

What to look for. To have these functions in your model. If any of them are not there, then you have either an outdated model (which is unlikely), or a household-class device.


The Russian buyer is well aware that the price depends not so much on the rich arsenal as on the reliability of the device. Something that looks beautiful and has many levers and bulbs can quickly fail. At the same time, a modest nondescript instrument of a reliable manufacturer, performing 1-3 functions, works for 10-15 years.

Almost all of the aforementioned devices operate on the principle of a cyclone, i.e. dust is collected directly into the tank. This facilitates waste disposal and tool maintenance. There are special paper bags for fine dry dust. If you decide to purchase a powerful dust collector, do not forget to clean and maintain it in time, and it will serve you throughout the entire work..
