How the Water Gets to the Washer

Pressure washers are part garden hose and part air compressor. A typical pressure washer has a motor that is either powered by gasoline or electricity. This motor powers the air intake system, which builds air pressure in an accompanying tank. A garden hose hooked up to the washer provides water to a separate tank.

At the end of each spray gun is a detachable nozzle. The nozzles are graded by the angle in which they spray. For instance, a zero-degree nozzle is a narrow, straight stream. This is the most powerful, as the water is concentrated and not spread out. As the degree increases, the pressure decreases.
