Westinghouse WPX3400
Gas 212cc pressure washer, 3400 PSI at 2.6 GPM · Reviewed by Drew · amazon.com live, Sept 24 2026
Why it scored a 85
The WPX3400 is the WPX3200 with more push: 3400 PSI and 2.6 GPM from the same 212cc engine for $349.00, $30.00 under its $379.00 list price. Value lands at 88, features at 86 and satisfaction at 90 from a 4.5-star average across 4,468 ratings. The listing also calls out compatibility with M22 surface cleaners, undercarriage cleaners and foam cannons. It finishes a point behind its sibling because reliability sits at 84 on a smaller, slightly lower-rated review base, and the extra 200 PSI is hard to notice on a deck. It is still a Strong Buy.

Should you buy the Westinghouse WPX3400?
The Westinghouse WPX3400 suits a homeowner who plans to add a surface cleaner for concrete and wants extra pressure headroom. At $349.00 it ranks #2 of 10 in our Pressure Washers category, one point behind the Westinghouse WPX3200, which costs $20 less and has more than twice the ratings. If you want a Honda engine and a triplex pump for heavy weekly use, the Simpson PowerShot PS3228 is the step up.
Where it earns its score
- Most flow in the group. Its 2.6 GPM is the highest flow listed here, paired with 3400 PSI, for $349.00.
- Attachment-friendly. Westinghouse lists compatibility with M22 surface cleaners, undercarriage cleaners and foam cannons.
- Bigger fuel tank. A 1-gallon gas tank and a half-gallon soap tank mean fewer stops on a long driveway.
- Same 3-year coverage. Service, labor and parts are covered for 3 years, matching the Westinghouse WPX3200 and Westinghouse ePX3100.
What to know first
- Warranty is the lowest factor at 78. Three years is solid, but it falls short of the 5-year pump coverage on the Simpson PowerShot PS3228.
- More pressure than most homes need. The extra 200 PSI over the Westinghouse WPX3200 matters for stripping, not for washing a car, where you will use the 40-degree tip anyway.
- Carbon monoxide and spray safety. Run it outdoors only, never in a garage or shed, even with the door open. Never point the spray at people or pets.
Our verdict
The Westinghouse WPX3400 scores 85, a Strong Buy that ranks #2 in Pressure Washers on Satisfaction (90), Value (88) and Features (86). Buy it if you want the most flow in the group and plan to run a surface cleaner. If you do not need the extra pressure, the Westinghouse WPX3200 (86) is $20 cheaper and better reviewed.
