Westinghouse WPX3400 Gas Pressure vs Simpson 3400 PSI Gas Pressure Washer,

Design and Build Quality

Both units feature robust steel frame constructions designed to withstand regular outdoor use. The Westinghouse WPX3400 Gas Pressure utilizes a welded steel frame with a powder-coated finish that resists corrosion, measuring 37 inches in length, 30 inches in width, and 21 inches in height. The Simpson 3400 PSI Gas Pressure Washer also boasts a tough steel frame construction, emphasizing durability for long-term ownership. Both machines are built to handle the vibrations and stresses associated with gas-powered cleaning equipment, ensuring stability during operation.

Cleaning Performance

When examining raw cleaning capability, both pressure washers deliver identical maximum pressure ratings. The Westinghouse WPX3400 Gas Pressure generates 3400 PSI, which is sufficient for stripping paint, cleaning driveways, and removing grime from siding. The Simpson 3400 PSI Gas Pressure Washer matches this with 3400 PSI of powerful, deep-cleaning water pressure. However, water volume differs slightly. The Westinghouse WPX3400 Gas Pressure provides 2.5 GPM, while the Simpson 3400 PSI Gas Pressure Washer offers 2.6 GPM. This slight increase in flow rate allows the Simpson model to cover surface area marginally faster.

Engine Specifications

The power source is a critical differentiator between these two models. The Westinghouse WPX3400 Gas Pressure is equipped with a 208 cc CRX engine that starts easily and includes a low-oil shutdown feature for protection. In comparison, the Simpson 3400 PSI Gas Pressure Washer houses a Heavy Duty Gas Powered 212cc 4-Stroke Westinghouse OHV Horizontal Shaft Engine with Recoil Start. The larger displacement in the Simpson model suggests potentially more torque and longevity under heavy loads, though both engines are designed for reliable homeowner use.

Hose and Reach

Reach and flexibility are vital for maneuvering around obstacles without moving the unit constantly. The Westinghouse WPX3400 Gas Pressure includes a Simpson MorFlex series 25 foot high-pressure hose that resists kinks and abrasion. It features non-marring properties to help protect finished surfaces. The Simpson 3400 PSI Gas Pressure Washer comes with a 25 foot Abrasion Resistant Super-Flex Hose. Both units provide the same length, ensuring users can clean areas up to 25 feet away from the power source without extension cords or additional hoses.

Mobility and Transport

Transporting a gas pressure washer across uneven terrain requires capable wheels. The Westinghouse WPX3400 Gas Pressure features 10 inch premium pneumatic tires that roll smoothly over gravel, grass, and curbs. The balanced layout improves transport, and the unit weighs 64 lb. The Simpson 3400 PSI Gas Pressure Washer is equipped with 12 inch High Profile, Never-Flat Wheels. While the Simpson model has larger diameter wheels which can help over obstacles, the pneumatic tires on the Westinghouse WPX3400 Gas Pressure may offer better shock absorption on rough ground.

Nozzles and Accessories

Versatility is determined by the variety of spray patterns available. The Westinghouse WPX3400 Gas Pressure includes four quick-connect pressure washer tips covering 0°, 15°, 40°, and soap nozzle configurations. The Simpson 3400 PSI Gas Pressure Washer provides 5 Quick Connect Nozzles including 0°, 15°, 25°, 40° and Soap. The additional 25° nozzle on the Simpson model offers a middle-ground spray pattern for general cleaning tasks that might be too aggressive for 40° but too narrow for 15°. Both are compatible with accessories like surface cleaners and foam cannons with M22 fittings.

Price and Value

Cost is often the deciding factor for homeowners. The Westinghouse WPX3400 Gas Pressure is listed at $329.00, making it the more budget-friendly option. The Simpson 3400 PSI Gas Pressure Washer is priced at $349.00. While the price difference is only $20, the Westinghouse WPX3400 Gas Pressure offers a lower entry point for users who do not require the extra flow rate or engine displacement. Both units represent solid value in the gas pressure washer category, with the choice depending on whether the user prioritizes initial cost or marginal performance gains.

Final Verdict

Choosing between these two models depends on specific cleaning needs and budget constraints. The Simpson 3400 PSI Gas Pressure Washer wins on performance metrics with a larger engine, higher GPM, and an extra nozzle option, justifying its slightly higher price for users tackling demanding jobs. However, the Westinghouse WPX3400 Gas Pressure remains a strong contender for standard homeowners who value cost savings and lighter weight. Both units are 49-State Compliant and feature maintenance-free axial cam pumps, ensuring reliable operation for decks, driveways, and vehicles.
