Power washing is the act of using pressurized water to clean dirt, algae, and other contaminants from outdoor surfaces. A power washer, otherwise known as a pressure washer, is the powered machine that makes cleaning the surface possible. Methods can vary depending on the machine being used, the surface that’s being cleaned, and the person performing the work.
The terms pressure washing and power washing are used interchangeably in many scenarios, and there is some debate as to whether they are actually different processes.
A pressure washing surface cleaner is a tool consisting of two to four high-pressure jets on a rotating bar that swivels when water is flowing. This action creates a uniformed cleaning pattern that can clean flat surfaces at a rapid rate.
Hydro-jet cleaning is a more powerful form of power washing, employed to remove buildup and debris in tanks and lines.
