Our test notes in full
The Westinghouse WPX3400 is a gas-powered pressure washer designed for homeowners who need serious cleaning muscle without stepping up to commercial-grade equipment. Powered by a reliable Westinghouse 209cc engine, this unit generates up to 3400 PSI and 2.6 GPM of water flow, giving it enough combined cleaning power to strip grime, mildew, and years of built-up dirt from driveways, siding, decks, fences, and outdoor furniture. The engine features a recoil start system that fires up quickly without the hassle of priming bulbs or choke adjustments common in older gas models, making it approachable even for users who have never operated a pressure washer before.
Built with durability and versatility in mind, the WPX3400 includes a set of five quick-connect nozzle tips—0, 15, 25, 40 degrees, and a soap applicator—allowing users to switch spray patterns instantly depending on the task at hand, from blasting caked-on mud to gently rinsing a car's finish. The onboard detergent tank simplifies soap application for jobs that require degreasing or extended dwell time, eliminating the need for a separate siphon hose. Westinghouse also equipped this model with a 25-foot high-pressure hose and never-flat wheels, giving it the mobility and reach needed to tackle large driveways or multi-story exteriors without constantly repositioning the unit.
From a practical standpoint, the WPX3400 balances power with user comfort, featuring an ergonomic spray gun with a comfortable trigger and an onboard storage system for nozzles, hose, and the power cord-free design inherent to gas models, keeping the unit tidy between uses. The low-oil shutdown sensor protects the engine from damage by automatically powering down when oil levels run low, extending the washer's lifespan with minimal maintenance effort required from the owner. Backed by Westinghouse's reputation for dependable outdoor power equipment, the WPX3400 stands out in the gas pressure washer market as a well-rounded choice for homeowners who want commercial-level cleaning performance in a machine sized and priced for residential use.

Cleans like a beast but it's definitely loud, as expected with a gas engine. The quick-connect tips make switching tasks super easy. Overall very happy with the purchase.
Solid machine for the price2023-05-20
Assembly took about 30 minutes but once set up, it's been dependable. Used it on my deck, siding, and patio furniture with excellent results. Just remember to keep up with basic engine maintenance.
Exceeded expectations2023-08-10
I was worried about handling a gas pressure washer for the first time, but this was surprisingly user-friendly. The wheels make it easy to move around the yard, and the soap tank is a nice touch.
