By Brittany Rowland<\/a><\/strong> Another common term used to describe pressure washers is GPM. This stands for gallons per minute, the amount of water shooting out of the pressure washer every minute. A high GPM ensures that the pressure washer shoots out enough water to wash away the grime on the surfaces you\u2019re cleaning.<\/p>\n You can multiply the PSI and the GPM to get the cleaning power rating. A high number guarantees that your pressure washer can handle tough cleaning tasks. <\/p>\n <\/p>\n

\nAs you research pressure washers, it\u2019s important to understand the measures used to gauge their power. PSI stands for pounds per square inch. This measures the water pressure coming out of the wand. To give you a reference point, know that a regular garden hose shoots out water at 30 to 40 PSI. In comparison, a pressure washer usually has a PSI of several thousands. It\u2019s what allows the pressure washer to break through layers of dirt and grime.<\/p>\n
