The best gas pressure washer
Our pick
Simpson PowerShot 3300 PSI Gas Pressure Washer
The Simpson PowerShot PS3228 is the strongest long-term gas choice here because its Honda GX200 and AAA triplex pump are better aligned with frequent, sustained cleaning than value axial-pump packages. The WPX3200 offers excellent measured output for less demanding ownership, while the CM61118 bundles a useful surface cleaner.
Why it fits this need
- Triplex versus axial pump architecture
- Sustained PSI and GPM for the job
- Main trade-off
- At roughly 77 pounds with a gas engine, it is louder, heavier and more maintenance-intensive than any corded electric here.
- Choose Westinghouse 3200 PSI Gas Pressure Washer instead when
- High-flow gas value
More reasons behind this pick
- Engine service, fuel storage and winterizing
- Noise, emissions and state availability
Gas models separated by pump class, engine, sustained flow, state availability and the maintenance their output requires.

Our pick and alternatives
Simpson, PS3228-S / PS3228
PowerShot 3300 PSI Gas Pressure Washer
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
Decisive facts
- 3300 PSI and 2.5 GPM manufacturer rating
- Honda GX200 engine paired with an AAA industrial triplex plunger pump
Trade-off
At roughly 77 pounds with a gas engine, it is louder, heavier and more maintenance-intensive than any corded electric here.
Westinghouse, WPX3200
3200 PSI Gas Pressure Washer
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
Decisive facts
- 3200 PSI and 2.5 GPM rating from a 212cc four-stroke engine
- Maintenance-free axial-cam pump, 25-foot hose and 1.6-liter detergent tank
Trade-off
Car and Driver measured about 95 dBA, and its 3000-PSI-class tested output is unnecessarily aggressive for routine car paint.
Simpson, CM61118
Clean Machine 3500 PSI Gas Pressure Washer
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
Decisive facts
- 3500 PSI and 2.5 GPM manufacturer rating
- Kohler SH270 engine with AAA AX300 Pro axial-cam pump, adjustable unloader and thermal relief
Trade-off
The AAA AX300 Pro is an enhanced axial-cam pump, not the serviceable triplex design used by the PS3228.
Champion, 100778
2800 PSI Gas Pressure Washer
A manageable mid-output gas washer with solid wheels, integrated detergent and enough flow for larger residential jobs.
Best forModerate gas power with simple mobility
Decisive facts
- 2800 PSI and 2.1 GPM from a 196cc Champion engine
- AR axial-cam pump, 25-foot high-pressure hose and integrated detergent tank
Trade-off
It uses an AR axial pump rather than a triplex unit, and its roughly 67-pound gas chassis still needs fuel, oil and seasonal storage care.
