Westinghouse WPX3400 Gas Pressure Washer, 3400 PSI, 2.6 GPM, 212cc Engine, 5 Nozzles and 25 ft. Hose

Tackle demanding outdoor cleaning with the Westinghouse WPX3400 gas pressure washer. Its 212cc four-stroke OHV engine and axial-cam pump deliver up to 3400 PSI and 2.6 GPM for cleaning concrete, brick, stone, siding, fences, decks, garage floors, vehicles, and patio furniture.

The WPX3400 includes five quick-connect nozzles, a lightweight spray gun, 25 ft. abrasion-resistant hose, and onboard detergent tank. A rugged steel frame and 12" never-flat wheels support mobility across driveways, lawns, and work areas.

3400 PSI and 2.6 GPM Performance

The WPX3400 combines high pressure with substantial water flow to loosen and rinse away dirt, mud, mildew, grease, and other outdoor buildup.

Its output is suitable for heavy-duty residential cleaning, but pressure should always be matched to the surface. Delicate materials can be damaged by excessive pressure or an overly concentrated spray.

212cc Four-Stroke Engine

A Westinghouse 212cc OHV horizontal-shaft engine powers the pressure washer without requiring an electrical connection. Recoil starting and the included engine oil support initial setup according to the quick-start guide.

Because it uses gasoline, the engine must be operated outdoors only.

Five Quick-Connect Nozzles

Select the appropriate spray pattern for each project:

• 0° nozzle for a highly concentrated stream

• 15° nozzle for strong cleaning

• 25° nozzle for general-purpose washing

• 40° nozzle for wider, gentler rinsing

• Soap applicator nozzle for detergent use

Begin with the widest appropriate nozzle, maintain a safe distance, and test an inconspicuous area before cleaning.

Onboard Detergent Tank

The integrated soap tank holds approximately 0.5 gal. of compatible pressure-washer detergent. Use the included soap nozzle to apply detergent according to the equipment and cleaning-product instructions.

Do not use bleach, solvents, or unapproved chemicals unless specifically authorized in the manufacturer’s manual.

EndraGrasp Spray Gun and 25 ft. Hose

The lightweight EndraGrasp spray gun connects to a 25 ft. abrasion-resistant hose, providing working range around vehicles, patios, fences, and exterior surfaces.

M22 Accessory Compatibility

The pressure washer supports compatible M22 accessories, including certain:

• Surface cleaners

• Undercarriage cleaners

• Foam cannons

• Extension accessories

Optional accessories are sold separately and must meet the pressure washer’s connection and operating specifications.

Steel Frame and Never-Flat Wheels

A rugged steel frame protects and supports the engine and pump. Two 12" never-flat wheels improve movement across suitable outdoor surfaces without requiring air-pressure maintenance.

Why It Stands Out

The WPX3400 combines 3400 PSI, 2.6 GPM, a 212cc engine, five spray patterns, onboard detergent storage, and M22 accessory support. Its steel frame, long hose, and never-flat wheels make it suitable for demanding residential cleaning without relying on an electrical outlet.

Operation and Safety

Operate this gasoline-powered pressure washer outdoors only and at least 20 ft. from occupied buildings where practical, with the exhaust directed away from doors, windows, and vents. Never run it inside a home, garage, shed, trailer, or other enclosed or partially enclosed area, even with doors open. Carbon monoxide can be fatal.

Allow the engine to cool before refueling. Never direct high-pressure water toward people, animals, electrical equipment, windows, or fragile surfaces. Wear eye protection and closed-toe footwear.

For cars, painted surfaces, siding, and wood, begin with the 40° nozzle at a safe distance. Avoid direct spraying of seals, electrical connectors, tires at close range, loose paint, and damaged materials.

Factory Testing Notice

Westinghouse pressure washers are functionally tested at the factory. A new unit may contain a minimal amount of residual oil or have a slight fuel odor.
