Pressure washers rated from 6 to 10 GPM or Higher
Pressure washers with the highest GPM ratings of 6 - 10 or higher are used in large-scale commercial applications. The main advantage of these machines is their ability to complete jobs faster. When two pressure washers have equal PSI output, the machine with higher GPM will complete the same job in less time. High GPM power washers are sometimes used with multiple hoses for even greater productivity.

Choosing The Right PSI For Your High GPM Pressure Washer
GPM is a great metric for determining the efficiency of a pressure washer. When it comes to specific use cases, however, PSI is a more important measure. Choosing a power washer with a PSI that’s too low may not get stains out, and a PSI that’s too high can damage or break underlying surfaces. For most lighter to medium-duty tasks like cleaning sidewalks or patio furniture, a PSI rating of 1,300 to 2,400 is normally enough. Heavy-duty tasks like cleaning garage floors and driveways will require a higher PSI of 3,000 to 3,500. Stripping paint, stains or other coatings will likely require a PSI rating of 4,000 or higher.
