With the help of an integrated pump, the pressure washer builds up a continuous water pressure and shoots a jet of water at high pressure via a nozzle onto the surface to be cleaned. A commercially available cleaner can thus build up a water pressure of up to 160 bar. Most of the devices are driven by an electric motor. Rarely, high-pressure cleaners with combustion engines are also used in private households.
The individual components of the devices are a precisely coordinated interaction of various mechanical parts in conjunction with a hydraulic system. The drive, motor and valve control must go hand in hand to ensure trouble-free operation.
How much does a high-pressure cleaner cost?
Electric pressure washers are available in all price ranges. Depending on workmanship, equipment and performance, the following price information is only a rough guide. As a rule, there are less expensive devices, but you usually have to cut back on quality.
The cheapest are electric high-pressure cleaners, where good devices are already available from around 150 euros. Followed by battery models, which cost from 200 euros with battery and charger. The most expensive are gasoline-powered pressure washers, where you should invest 300 euros or more.
