Westinghouse WPX3400 Gas Pressure Washer, 3400 PSI and 2.6 GPM, Onboard Soap Tank, Spray Gun and Wand, 5 Nozzle Set, for Cars/Fences/Driveways/Homes/Patios/Furniture

The Westinghouse WPX3400 is a gas-powered pressure washer designed to handle demanding cleaning projects around the home. Powered by a 212cc 4-stroke OHV engine, it delivers 3400 PSI of water pressure at a flow rate of 2.6 gallons per minute. This makes it a practical option for homeowners who need to clear dirt and grime from driveways, decks, house siding, fences, railings, garage floors, cars, and patio furniture.

Operating the unit is straightforward, featuring a manual recoil start engine and an axial cam pump that requires no routine maintenance. It comes equipped with a 25-foot abrasion-resistant hose, a lightweight spray gun, and five quick-connect nozzles ranging from 0 degrees for intense spot cleaning to 40 degrees for wider coverage, along with a dedicated soap nozzle. The machine incorporates a one-gallon gas tank alongside a half-gallon onboard soap tank, allowing you to feed soap directly through the spray system.

Built on a heavy-duty steel frame, the pressure washer relies on 12-inch high-profile never-flat wheels to move across rough yard terrain easily. Its standard M22 fittings mean you can attach compatible accessories like surface cleaners, undercarriage sprayers, or foam cannons. Everything needed to start working comes in the package, including engine oil, basic assembly tools, and a quick start guide.

As a gas-powered model with a recoil pull start, operating it requires keeping gasoline on hand and manually pulling a cord to ignite the engine. Factory testing means the unit may arrive with a slight residual oil or fuel odor right out of the box. Additionally, while the 25-foot hose provides good reach, larger properties may require rolling the frame along with you as you work.

Verdict: The Westinghouse WPX3400 is a solid choice for homeowners seeking strong water pressure for regular outdoor maintenance like washing driveways, fences, and siding. Its onboard soap tank, included oil, and sturdy wheel design make it ready for heavy cleaning right out of the box.
