SIMPSON Cleaning FAQ

Who is SIMPSON Cleaning best for?

Industry leader in welded-steel gas pressure washers powered by CRX165 and Honda GX200 engines with axial and AAA triplex pumps, plus 15-inch steel surface cleaners. Best for: MegaShot homeowner & PowerShot commercial gas.

Is HydroWashers.com affiliated with SIMPSON Cleaning?

No. HydroWashers.com is independent, SIMPSON Cleaning doesn’t pay for placement, and all brand names and trademarks belong to their owners.

What is more important on a pressure washer: PSI or GPM?

Both matter together—multiply PSI × GPM to get Cleaning Units (CU). PSI (pounds per square inch) is the stripping force that breaks grime loose, while GPM (gallons per minute) is the water volume that flushes dirt away. For washing cars, you actually want moderate pressure (1,500–2,100 PSI) and higher GPM (1.5–1.76+ GPM) so you don't damage paint.
