A high-pressure cleaner is a machine that uses a power unit to make the Electric Plunger Pump produce high-pressure water to wash the surface of the object. It can peel off and wash away the dirt to achieve the purpose of cleaning the surface of the object. Because it uses high-pressure water jets to clean up dirt, high-pressure cleaning is also recognized as one of the most scientific, economic, and environmentally friendly cleaning methods in the world.

It can be divided into cold water pressure washers, hot water pressure washers, Electric Pressure Washer, gasoline engine driven high-pressure washers, etc. The biggest difference between the two is that the hot water washing machine adds a heating device, which uses a combustion cylinder or an electric heating device to heat the water. However, the price of the hot water washing machine is high and the running cost is high (because diesel or electricity is used to heat the water), many professional customers will choose hot water washing machines.
