What are PSI and GPM?
PSI stands for Pounds per Square Inch. This refers to the amount of pressure that the pressure washer can produce. PSI is what provides the power to penetrate what you are trying to remove and clean from the surface.
When a pressure washer has a high PSI, you can count on it to remove the most stubborn gunk. The PSI of effective commercial pressure washers typically ranges from about 2,000 to 3,000.
GPM stands for Gallons per Minute and is the amount of water flow that comes out of the water gun on the pressure washer. GPM refers to the ability of the machine to break down and clean dirt and stains.
The higher the GPM is in a pressure washer, the quicker you can wash a surface. Typically the most effective GPM for a commercial pressure washer ranges from 2.2 to 10.
