Which pressure washer is best for frequent professional-style use

Top pick

Simpson PowerShot 3300 PSI Gas Pressure Washer

Simpson PowerShot 3300 PSI Gas Pressure Washer

Within this residential-market set, the Simpson PowerShot PS3228 is the closest fit, because its Honda GX200 and AAA triplex pump are designed for serviceability and repeated output. Confirm the warranty terms for paid use, and step up to a true commercial hot-water or belt-drive machine when the workload calls for it.

Why it suits this job

  • Triplex pump that is serviceable, plus parts access
  • Engine duty, service intervals and warranty
The catch
Weighing roughly 77 pounds and running a gas engine, it is louder, heavier and needs more upkeep than any of the corded electrics listed here.

More reasons we picked it
  • Sustained pressure and flow rather than a brief maximum
  • Compatibility with commercial hoses, guns and surface cleaners
