Water Flow (GPM)
”
Definition:
The unit for water flow is GPM (gallons per minute), which is the amount/quantity of water used in one minute. The volume of water determines how fast dirt can be removed from the surface once the bond between the debris and the surface has been broken. The unit with a higher GPM level will require less cleaning time; consequently, a washer with a lower GPM level will entail more time for the same job.
