Westinghouse WPX3400

In this westinghouse wpx3400 review, the Westinghouse WPX3400 is the number two pick of nine in our 2026 guide to the best gas pressure washers, and our label for it is simple: best for heavier home cleaning. The machine pairs 3,400 PSI with a 2.6 GPM flow rate, runs on a 212cc Westinghouse OHV four-stroke engine, and costs $349. It holds 4.5 stars from 4,469 Amazon ratings. This is a gas washer for homeowners with long driveways, wide patios, two-story siding, or fence lines that take an afternoon to spray down. The box includes engine oil, an oil funnel, five nozzle tips, a 25-foot hose, and a pro-style wand, backed by a three-year limited manufacturer warranty on service, labor, and parts.

On the performance side, the 2.6 GPM flow rate matters as much as the 3,400 PSI figure, because flow rinses dirt away instead of only blasting it loose. In practice, that combination pushes about two and a half gallons of water and soap through the pump every minute, so stained concrete and weathered deck boards clear faster than with lower-output machines. Five quick-connect nozzles cover the range: 0 degrees for a pinpoint stream, 15 and 25 degrees for concrete and siding, 40 degrees for a gentle rinse, and a soap tip fed by the half-gallon tank. Meanwhile, the 25-foot abrasion-resistant Super-Flex hose reaches most single-car driveways without moving the unit, and the 12-inch never-flat wheels roll over gravel and curbs. A recoil start fires the 212cc engine, and the axial cam pump needs no maintenance. At 28.6 kg (63 pounds), it is a two-hand lift.

Value is where the Westinghouse WPX3400 makes its case. At $349 it sits $20 above the WPX3200, and that small gap buys 200 extra PSI plus a 1-gallon fuel tank, so long fence lines and wide driveways finish without a mid-job refill. As a result, homeowners with real square footage to clean get more machine per dollar here than from either neighbor in the ranking. Even so, this is not a commercial tool: the axial cam pump suits homeowner duty, not eight-hour shifts, and the recoil start means no push-button convenience. It also ships after a factory functional test, so a faint oil or fuel smell is normal. If you clean a long driveway, a big deck, or two-story siding a few times a year, the WPX3400 is the one to buy. If you only rinse a small patio, keep your money and step down.
