Pressure washers make use of the fact that water under high pressure can remove many types of dirt and also moss growth.
Such devices save time when cleaning the terrace and are also much more comfortable on the move than with a brush and a bucket of water.
Technically, the work is made easier on wheels by using a piston pump to pressurize incoming water.
The pressurized water is shot out through the lance of the high pressure cleaner and can be used for cleaning work.
The pressure can then be further regulated on the spray lance, whereby different nozzles can be attached to this, in order to give every surface the perfect cleaning.
High-pressure cleaners are best used against organic compounds such as algae or moss, but they can also be used to remove lime, rust and other deposits from patios, cars and gutters.
The range of applications can be expanded as required with the appropriate accessories.
When buying, you have to differentiate between maximum and working pressure; for use at home, a nominal pressure of approx. 100-120 bar is sufficient.
However, the pressure should not be the only deciding factor for purchase, because the so-called flushing capacity also plays an important role here and should ideally be around 500 liters per hour.
In the test, the high-pressure cleaners had to clean various surfaces.
It wasn't just about strength, because cleaning a wooden facade also requires the appropriate sensitivity.
Another test criterion was handling - how well can the devices be stowed away?
Can the detergent be dosed?
Does the cleaner fall over if you pull on the hose?
High pressure cleaner in the test
The test portal AllesBeste has tested 25 high-pressure cleaners.
The best high-pressure cleaner was the Kärcher K3 Full Control.
Its water jet could be dosed extremely well and reliably cleaned even angled areas.
In order to properly clean both the driveway and the car, the Kärcher also has numerous attachments with which you are well equipped for almost all household chores.
The only minor flaw is the plastic connections for the hoses, because, as experience shows, they are often pulled, which can quickly lead to the connections breaking off with the Kärcher.
