 Correct IncorrectPSI breaks the dirt bond, but GPM provides the water volume to wash away and flush loosened debris. Higher GPM allows operators to use wide surface cleaner attachments at much faster walking speeds.

In professional pressure washing, why is Gallons Per Minute (GPM) considered more important than PSI for surface cleaning speed?

• Water volume (GPM) flushes away loosened dirt, enabling faster cleaning passes over wide areas
• High GPM allows cold water to turn into boiling steam
• GPM makes the gas engine run quieter
• GPM decreases the weight of the spray wand
