Then we advise you to take a closer look at the vacuum cleaners of the German brand - powerful devices can suck in not only dust, but also sand, wood chips, dry paint, and cope with severe pollution. There are devices for working in production conditions. It remains only to make the right choice.

Our article will help in this matter. We outlined the design and functional features of Karcher vacuum cleaners, compiled a rating of the best offers of the company and prepared a summary table of their characteristics, as well as practical recommendations for choosing construction cleaning equipment.

Features of brand building vacuum cleaners

Kärcher construction vacuum cleaners are divided into two types: household and industrial.

Household Aggregates Suitable for cleaning at home during and after repairs. They collect fine debris, cement, asbestos, gypsum, wood dust and liquids.

From ordinary household vacuum cleaners are more reliable, power and volume of garbage containers.

Connecting the tool to a vacuum cleaner
There are models with a socket for connecting a tool that can be useful in home workshops.

The design of household appliances includes a wider hose, shockproof housing, multi-stage filtration system.

Any such apparatus can be used without a bag if it is intended to collect liquids or debris with large particles.For fine dust it is better to put a bag in order to extend the life of the main filter.

Industrial (professional) vacuum cleaners are used by construction and repair crews for continuous work, as well as for commercial purposes in enterprises with other activities.

The devices are reliable, roomy (25-110 l), can work for a long time without interruptions and are simply distinguished by a huge suction force - in some models this figure reaches 300 mbar.

The design of such devices includes large wheels that provide maneuverability, and ergonomic handles for carrying.

Industrial vacuum cleaner Karcher
In the lineup of the manufacturer there are devices with iron wheel holders and chippers on the body. Powerful, maneuverable and functional - this technique will be a great helper

As for the functionality, industrial units can collect everything in a row - both solid waste and liquids, as well as connect to and work with a power tool (some models).

The principle of their use is similar to the economic one - you can use the bag or do without it. But such units are not suitable for cleaning their own housing and other household needs because of their impressive size and weight.

What to look before buying?

A powerful construction vacuum cleaner eliminates the tedious long-term work with a broom, saves and protects against harmful microscopic dust.To find your model, you need to clearly set the tasks that a useful device will handle.

Tip # 1 - choose the type of dust collector and filter

Construction vacuum cleaners are different in functionality, configuration, dimensions. First of all, we look at the type of dust collector.

There are three traditional varieties:

  1. Cloth bag.
  2. Paper bag.
  3. Cyclone (container).

A significant advantage of Karcher household vacuum cleaners is the ability to work with and without a bag. In the first case, filtering is better, but less container volume.

AT bagless vacuum cleaners A convenient system for collecting large debris and liquids is implemented, but they are distinguished by increased noise. And if you work with small particles, it will be too dusty. It remains only to choose the right kit for work in certain conditions.

Vacuum cleaner bag Karcher
On dust collectors, you can save and buy non-original bags, but you need to use high-quality filters

Fabric bags finely dispersed dust is poorly retained and labor-intensive during cleaning, but they are reusable.

Paper products provide more thorough filtering, but they are thrown away with the contents, require constant replacement and are torn from coarse particles of garbage.

Check availability before purchase. bags for carcher modelswhether non-original consumables are suitable, because the cost of some branded bags is quite high.

In addition to the tank, you should pay attention to the filtration system. The design of the vacuum cleaner is equipped with disposable and reusable filters. Not only the quality of cleaning, but also the degree of engine wear depends on their variety and cost.

In budget models, you have to change and clean filters much more often than in expensive counterparts.

Tip # 2 - look at the power parameters

Worth comparing power consumption for different devices: the higher this number, the more thorough the cleaning will be. But this parameter affects not only performance, but also increases power consumption.

For domestic conditions and the work of a private repair and construction team, an apparatus with a power of 1000-1400 watts is quite enough. A device with such a range of digits will not overload the network and ensure high-quality cleaning of small and medium volumes of garbage.

The next indicator is degree of depression. Devices with a digit up to 120 mbar are suitable for cleaning small debris, dry mixtures. If the value is greater than 120, such a vacuum cleaner can be used for rooms contaminated with large waste.

Vacuum cleaner Karcher
For Karcher vacuum cleaners, the degree of vacuum is indicated in mbar, so to compare this indicator with models from other manufacturers, you need a table

Tip # 3 - select the tank volume and add-ons

Let's move on to the tank capacity. For household needs and finishing work, an apparatus with a container volume of up to 50 liters is enough. If more serious construction and repair tasks are set before the device, we buy a professional model with an indicator of 50 liters or more.

Trash bin
When choosing the volume of the garbage tank, consider the main drawback of a large dust collector - the need to move, shake out the container itself or throw out the collected garbage with the bag.

If you need a power outlet for a power tool, look at the characteristics of the devices: Karcher works with equipment with a minimum power of 100W and a maximum of 2100W.

When working with a power tool at the same time, the vacuum cleaner turns on only after turning on the “partner”, and turns off also behind it, but with a slight delay.

  1. Svetlana

    I am engaged in apartment renovation, and we all bought a construction vacuum cleaner Karcher WD 3 P Premium. This model is completely suitable for us. Since the vacuum cleaner has a lot of power, it’s good for them to remove any construction debris: cement, earth, chips and other fragments. The main thing is that it weighs little, so it is easy to control and easy to move around the room: cleaning with it is quick.

  2. I do not quite understand from the material that these vacuum cleaners have both a bag and a container for collecting garbage?
