Pressure washers are suitable for many cleaning jobs around the house. As a rule, you connect a high-pressure cleaner to the water pipe using a garden hose (about 4 bar) an. However, many devices are also self-priming, can therefore help themselves from a water tank A pump generates a high water pressure of approx 100 to 150 bar, which exits through a small high-pressure nozzle as a sharply focused jet with a high cleaning effect. With the high water pressure, dirt particles are removed, for example on terrace floors, solved. A high water flow finally washes away the dirt quickly. The cleaning performance of a high-pressure cleaner can therefore be read from the pressure and the amount of water. However, even with the most powerful high-pressure cleaners, the water consumption is significantly lower, than just spraying with a garden hose. Then would about 3500 liters of water per hour flow through the water meter.
Anyone who only uses a high-pressure cleaner occasionally, does not have to come with a device at the same time 150 cash and 650 liters of water flow per minute. Even with the weaker and cheaper devices you can usually reach your goal. It just takes a lot longer, to
stubborn dirt has been loosened and large areas have been cleaned. Occasional users in particular should pay attention to high-quality materials in the pump. If the high-pressure cleaner is not used for a long period of time, otherwise corrosion can easily occur on the components in the pump system.
No matter, whether you buy an expensive or inexpensive device, in winter, the high-pressure cleaner belongs in a frost-free storage room. Otherwise it can be, that the system seals are damaged by frost and must be replaced.
SHOPPING TIP
■ Hochdruckreiniger mit hohem Druck und großem Wasserdurchfluss ermöglichen schnelleres Arbeiten.
■ Bei Geräten mit Autostopp läuft der Motor nur, when you squirt, in devices with bypass control, it continues to make noise even during breaks in work.
■ Achten Sie beim Kauf auf die mitgelieferten Düsen: Around- or flat jet (for general cleaning work), Rotationsdüse (for particularly stubborn dirt), low pressure jet (for spraying with and without detergent), Vario nozzles for jet types, which are set at the nozzle.
■ Eine Waschbürste ist für schonendes Reinigen von Lackflächen erforderlich.
