What are PSI and GPM and how do they relate to a pressure washer’s performance?
Joe's Assistant

  • A pressure washer’s cleaning efficiency is a combined measure of the PSI (pounds per square inch) and the GPM (gallons per minute).
  • PSI refers to the amount of cleaning pressure that the pressure washer can generate, the “dirt-scouring” action.
  • GPM refers to the amount of water that is flowing from the unit, the “rinsing” action.
  • The SPX3000® XTREAM is an ideal pressure washing system that achieves top-rated marks on both of these performance indicators to effectively scour away deep-seated dirt with 2200 PSI max  (at initial discharge per CSA internal pressure testing) and effectively rinse it away with up to 1.65 GPM max (with nozzle open at minimum pressure) of water flow.
