Westinghouse ePX3500 Electric Pressure Washer
The Westinghouse ePX3500 delivers 2500 max PSI with a 1.76 GPM flow at the base setting, and 2000 PSI / 1.2 GPM rated flow for lighter tasks. Its pro-style steel wand with quick-connect nozzles (0°, 15°, 25°, turbo, soap) supports a versatile cleaning kit for decks, fences, and vehicles. A compact footprint with four quick-lock wheels and an anti-tipping design improves stability during use, and the onboard 20-ounce soap tank enables easier detergent applications. Ideal for homeowners who require strong electric performance with straightforward maintenance.
Key features include a 25′ easy-coil nylon braided hose and a lightweight build at 19 pounds. While it excels on lighter heavy-duty tasks, it remains a practical entry point for urban spaces and smaller exteriors where noise and emissions are considerations.
Westinghouse WPX3400 Gas Pressure Washer
The WPX3400 is a robust gas-powered unit with 3400 PSI and 2.6 GPM, designed for deeper cleaning on concrete, siding, and large exterior surfaces. It includes a convenient onboard soap tank, a 25-foot abrasion-resistant hose, and a 5-nozzle spray set (0°, 15°, 25°, 40°, Soap). The system supports compatible pressure-washer accessories such as surface cleaners and foam cannons, expanding its versatility for contractors and serious homeowners alike. Gas engines provide mobility without a power outlet, enabling extended cleaning sessions away from electrical sources.
Simpson Cleaning 3600 PSI Gas Pressure Washer
The Simpson 3600 PSI unit targets professional and contractor workloads with a Honda GX200 engine and a AAA industrial triplex pump delivering 3600 PSI at 2.5 GPM. The PowerBoost technology provides higher nozzle pressure, while a 10-inch pneumatic tire setup supports maneuverability on varied terrains. It ships with a robust 35-foot MorFlex hose and five quick-connect nozzles (0°, 15°, 25°, 40°, Soap), making it a strong choice for wood restoration, deck cleaning, and other demanding tasks. This model emphasizes durability and reliability for long-term professional use.
Westinghouse WPX3000e Electric Pressure Washer
The WPX3000e combines 3000 max PSI with 1.76 max GPM flow, paired with a long-lasting induction motor. It features a compact onboard soap tank and a 25′ hose with five quick-connect nozzles (0°, 15°, 25°, soap, turbo). The unit is designed for elevated reliability and consistent performance across residential applications like decks, sidewalks, and garage floors. Its electric design reduces noise and emissions while offering straightforward maintenance and storage convenience for smaller to mid-size cleaning jobs.
Simpson Cleaning 3400 PSI Gas Pressure Washer
The Simpson 3400 PSI residential gas washer is built for homeowners needing solid power without commercial-scale equipment. It uses a CRX engine and an OEM axial cam pump delivering 3400 PSI at 2.5 GPM, with a 25-foot MorFlex hose that resists kinks. The set includes a non-marring hose and quick-connect fittings for rapid setup. It’s 49-state compliant (not sold in California), offering dependable cleaning for decks, driveways, and siding with practical portability for typical home projects.
Buying Guide
Power Source: Electric models are quieter and suitable for HOA-compliant neighborhoods and limited spaces, while gas units deliver more continuous cleaning power for larger or tougher jobs away from outlets.
PSI and GPM: Higher PSI and GPM translate to faster cleaning, especially on tough surfaces. For wood restoration, aim for 3000+ PSI with 2.5+ GPM; for lighter tasks, 2000–2500 PSI with 1.2–1.8 GPM can suffice.
Portability and Stability: Look for anti-tipping features, wheels, and a balanced design. A longer hose increases reach but adds weight; consider storage footprint if space is limited.
Nozzle Variety: A five-nozzle set with a turbo and soap nozzle provides versatility across surfaces from soft wood to concrete. Quick-connect nozzles reduce downtime during job transitions.
Onboard Soap and Detergent: Built-in tanks simplify applying cleaners to driveways and fences. Ensure capacity fits your typical workload and that the detergent is compatible with your surfaces.
Durability and Maintenance: Engine quality (Honda for gas models, induction motors for electric), pump type (triplex vs. axial cam), and build materials influence longevity. Regular maintenance reduces downtime and extends service life.
Warranty and Support: Check manufacturer warranties and accessible service centers in your area. A strong warranty can offset higher upfront costs for heavy-use scenarios.
Intended Use: For occasional residential cleaning, electric models often suffice. For contractor-grade workloads, gas-powered units with robust pumps and larger hoses are typically preferred for durability and continuous performance.
