Features of the brand’s construction vacuum cleaners
Construction vacuum cleaners from Kärcher are divided into two types: household and industrial.
Household units Suitable for cleaning at home both during and after renovation. They collect small debris, cement, asbestos, gypsum, wood dust and liquids.
Household vacuum cleaners differ from ordinary household vacuum cleaners in their greater reliability, power and volume of waste containers.
The design of household appliances includes a wider hose, impact-resistant housing, and a multi-stage filtration system.
Any similar device can be used without a bag if liquids or debris with large particles are expected to be collected. For fine dust, it is better to install a bag to extend the life of the main filter.
Industrial (professional) vacuum cleaners are used by construction and repair teams during production work, as well as for commercial purposes at enterprises with other types of activities.
The devices are reliable, spacious (25-110 l), can work for a long time without interruption and are characterized by simply enormous suction power - in some models this figure reaches 300 mBar.
The design of such devices includes large wheels that provide maneuverability and ergonomic handles for carrying.
As for functionality, industrial units can collect everything - both solid waste and liquids, as well as connect to a power tool and work with it (some models).
The principle of their use is similar to household ones - you can use a bag or do without it. But such units are not suitable for cleaning your own home and other household needs due to their impressive dimensions and weight.
Top 10 best construction models
The famous German brand produces several lines of construction vacuum cleaners. Their main purpose is cleaning during and after repair work.
But it is no coincidence that they are called economic. The devices find their use in the garage, in the country house and garden, in the apartment and workshop. Powerful devices are purchased by allergy sufferers to get rid of household dust and owners of long-haired animals to clean carpets.
The rating includes models that not only cope well with their main task, but can also be used on the farm for other needs.

What to look for before buying?
A powerful construction vacuum cleaner eliminates tedious long-term work with a broom, saves and protects from harmful microscopic dust. To find your model, you need to clearly define the tasks that the useful device will cope with.
Tip #1 - choose the type of dust collector and filter
Construction vacuum cleaners vary in functionality, configuration, and dimensions. First of all, we look at the type of dust collector.
There are three traditional varieties:
- Fabric bag.
- Paper bag.
- Cyclone (container).
A significant advantage of household vacuum cleaners from Karcher is the ability to work with or without a bag. In the first case, filtration is better, but the container volume is smaller.
IN bagless construction vacuum cleaners a convenient system for collecting large debris and liquids has been implemented, but they are characterized by increased noise. And if you work with small particles, it will be too dusty. All that remains is to choose the right kit for work in certain conditions.
Fabric bags They do not retain fine dust well and are labor-intensive during cleaning, but they are reusable.
Paper products provide more thorough filtration, but they are thrown away along with the contents, require constant replacement and are torn by coarse debris particles.
Check availability before purchasing bags for Karcher models, are non-original consumables 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 includes disposable and reusable filters. Not only the quality of cleaning, but also the degree of engine wear depends on their type and cost.
In budget models you have to change and clean filters much more often than in expensive analogues.
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 not only affects performance, but also increases power consumption.
For domestic conditions and the work of a private repair and construction team, a device with a power of 1000-1400 W is quite sufficient. A device with such a range of numbers will not overload the network and will provide high-quality cleaning of small and medium volumes of garbage.
The next indicator is vacuum degree. Devices with a reading of up to 120 mbar are suitable for cleaning small debris and dry mixtures. If the value is greater than 120, such a vacuum cleaner can be used for rooms contaminated with large waste.
Tip #3 - choose tank volume and add-ons
Let's move on to the tank capacity. For household needs and finishing work, a device with a container volume of up to 50 liters is sufficient.If the device is tasked with more serious construction and repair tasks, we buy a professional model with an indicator of 50 liters or more.
If you need an outlet for a power tool, look at the characteristics of the devices: Karcher works with equipment whose minimum power is 100W, maximum - 2100W.
When working simultaneously with a power tool, the vacuum cleaner turns on only after the “partner” is turned on, and also turns off after it, but with a slight delay.
