What PSI Pressure Washer Do I Need?

Not only the height in bar indicates the power of the high-pressure cleaner, but the power displayed in Watt also indicates the power.

The capabilities of pressure washers vary widely. The lightest models have a 1200 Watt motor and the heavier models can have a motor capacity of 400 Volt. A typical consumer pressure washer has a power between 1200 and 2500 Watts.
