Our pick

The Simpson PowerShot PS3228 leads large-area work because its 2.5 GPM rating, triplex pump and surface-cleaner compatibility support repeated wide passes. The WPX3200 is the value gas alternative. Use the Greenworks GPW3002A when lower noise and maintenance outweigh the longer cleaning time.
Machines for broad patios and long driveways, where flow, surface-cleaner support, hose logistics and pump duty determine job time.

Simpson, PS3228-S / PS3228
A serious residential gas washer built around a Honda GX200 engine and serviceable AAA triplex pump for repeated large-area work.
Winner whenHeavy concrete and frequent exterior cleaning
At roughly 77 pounds with a gas engine, it is louder, heavier and more maintenance-intensive than any corded electric here.

Westinghouse, WPX3200
A high-flow gas value that delivered near its claims in independent testing and moves dirt quickly from broad concrete and masonry.
Best forHigh-flow gas value
Car and Driver measured about 95 dBA, and its 3000-PSI-class tested output is unnecessarily aggressive for routine car paint.

Simpson, CM61118
A 50-state gas package pairing strong residential output with an included 15-inch steel surface scrubber for ready-to-go concrete cleaning.
Best forGas package with surface cleaner included
The AAA AX300 Pro is an enhanced axial-cam pump, not the serviceable triplex design used by the PS3228.

Greenworks, GPW3002A Gen 2
A high-output corded model with a stable wheeled frame, brushless motor and enough operating pressure for most residential hard-surface work.
Best forBest all-round electric pressure washer
Its headline 3000 PSI and 2.0 GPM are separate operating points: Greenworks specifies 1.1 GPM at 3000 PSI and 2.0 GPM at 100 PSI.
