Westinghouse WPX3400 Gas Pressure Washer
The Westinghouse WPX3400 Gas model offers 3400 PSI with 2.6 GPM for deep cleaning on tough outdoor surfaces. It includes a 1 gallon gas tank and a 0.5 gallon onboard soap tank, plus a 25-foot abrasion-resistant hose and a 5-nozzle set. The setup supports compatible accessories like surface cleaners and foam cannons with M22 fittings. Best for homeowners who frequently tackle stubborn grime on driveways, siding, and patios. A limitation is that gas models require fuel management and more maintenance than electric units.
Westinghouse WPX3400e Electric Pressure Washer
The WPX3400e provides 3400 max PSI and 2.0 max GPM with a brushless motor for quieter operation and lower maintenance. It includes an onboard soap tank, a 25-foot hose, and five quick-connect nozzles similar to the gas model, enabling versatile cleaning from tough to delicate surfaces. This option is best for households seeking strong cleaning power without fuel handling or exhaust, but note the electric units can have limitations in hotter climates or for extended, heavy-duty use without a dedicated outlet.

The Simpson CM61083Clean Machine offers 3400 PSI at 2.5 GPM with a CRX engine and an OEM Technologies axial cam pump. It ships with a 25-foot MorFlex hose that resists kinks and is non-marring, aiding gentle surface protection. This model is well-suited for homeowners needing robust cleaning for decks, driveways, and siding, with a focus on reliability and ease of maintenance. A limitation is that it is not California-compliant, which may affect availability in certain areas.
MUTAOMAY 3500 PSI Gas Pressure Washer

It includes four quick-connect nozzles (0°, 25°, 40°, and soap) and a 25-foot hose, with the nozzle set designed for a range of tasks from deep cleaning to gentle soap applications. This model is best for those needing higher PSI capacity with a compact footprint and accessible maintenance. A potential drawback is that data highlights emphasize performance rather than long-term warranty details.

The DEWALT DXPW3300-S provides 3300 PSI with 2.4 GPM and a robust welded steel frame. It features a reliable 208cc engine and a thermal relief valve to help prevent overheating during extended use.

Choose this if you want a portable, durable option for decks, patios, and exterior cleaning, but be mindful that it sits slightly below 3400 PSI on the high end.
Buying Guide
What should you consider when choosing a 3400 psi washer?
- Power source: Gas engines offer maximum cleaning power and portability but require fueling and more maintenance. Electric models run quietly with fewer emissions and lower ongoing maintenance, ideal for smaller homes or shared spaces.
- PSI and GPM needs: Higher PSI helps remove stubborn stains; higher GPM helps complete larger jobs faster. Match your typical tasks to the right balance of PSI and GPM.
- Nozzle variety: A five-nozzle set (0°, 15°, 25°, 40°, and soap) covers most tasks. Quick-connect nozzles speed setup and reduce downtime.
- Hose length and durability: A longer hose improves reach but can add weight. Look for abrasion-resistant, non-marring hoses for delicate surfaces.
- Maintenance and durability: Look for axial cam pumps and thermal relief valves, which improve long-term reliability. A solid frame and wheels aid portability on uneven terrain.
- Accessories compatibility: Check for compatibility with surface cleaners, undercarriage cleaners, and foam cannons to expand capabilities.
