Which gas pressure washer is best
Top pick
Simpson PowerShot 3300 PSI Gas Pressure Washer
Of the gas washers here, the Simpson PowerShot PS3228 is the strongest for the long term. Its Honda GX200 and AAA triplex pump suit frequent, sustained cleaning better than value axial-pump packages do. The WPX3200 delivers excellent measured output with less demanding ownership, and the CM61118 comes bundled with a useful surface cleaner.
Why it suits this job
- Triplex or axial pump design
- PSI and GPM the job needs, sustained
- 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.
- Go with Westinghouse 3200 PSI Gas Pressure Washer if
- Gas value with high flow
More reasons we picked it
- Servicing the engine, storing fuel and winterizing

Westinghouse, WPX3200

Best forGas value with high flow
Key facts
- A 212cc four-stroke engine with a rating of 3200 PSI and 2.5 GPM
- A 1.6-liter detergent tank, 25-foot hose and maintenance-free axial-cam pump
The catch
Car and Driver measured about 95 dBA. Its 3000-PSI-class tested output is more aggressive than routine car paint needs.
Simpson, CM61118
Clean Machine 3500 PSI Gas Pressure Washer
This 50-state gas package pairs strong residential output with a 15-inch steel surface scrubber in the box, so you can start on concrete right away.

- Manufacturer rating of 3500 PSI and 2.5 GPM
- AAA AX300 Pro axial-cam pump, adjustable unloader and thermal relief, driven by a Kohler SH270 engine
The catch
Its AAA AX300 Pro pump is an upgraded axial-cam design. The PS3228 uses the serviceable triplex type.
Champion, 100778
2800 PSI Gas Pressure Washer
A mid-output gas washer that is easy enough to handle, with solid wheels, built-in detergent and the flow for bigger jobs around the house.
Best forMiddle-of-the-road gas power that is easy to move
Key facts
- A 196cc Champion engine producing 2800 PSI and 2.1 GPM
- An integrated detergent tank, 25-foot high-pressure hose and AR axial-cam pump
The catch
A triplex it is not, since it uses an AR axial pump. The roughly 67-pound gas chassis also still calls for fuel, oil and attention when it is put away for the season.
