A pressure washer is a high pressure mechanical sprayer that can be used to remove loose paint, mold, grime, dust, mud, and dirt from surfaces and objects such as buildings, vehicles, concrete surfaces, etc. The volume of a pressure washer is expressed in either gallons or litres per minute, often designed into the pump and not variable.
