Westinghouse WPX2700 Gas Pressure Washer
The Westinghouse WPX2700 delivers up to 2700 PSI and 2.3 GPM, making it a strong option for demanding outdoor cleaning tasks. It features onboard soap tank capability, a spray gun and wand, and a five-nozzle set (including a soap nozzle) for versatile applications on decks, driveways, siding, and vehicles. The pump is brass and the system emphasizes portability with a compact footprint and included wheels for maneuverability. Users benefit from a robust cleaning punch from a gas-powered unit, suitable for larger areas or stubborn grime.
Westinghouse ePX3050 Electric Pressure Washer
The ePX3050 provides 2100 max PSI with 1.76 max GPM, making it a balanced electric option for homeowners. It includes a foam cannon and a turbo nozzle for enhanced cleaning of patios, fencing, and siding. The unit is designed to be user-friendly and compact, with an axial pump and a 26-inch profile for easy storage. Its included accessories and onboard design support versatile cleaning tasks while remaining relatively easy to transport and set up.
Westinghouse ePX3100 Electric Pressure Washer
The ePX3100 shares a similar electric platform with the ePX3050, offering 1.76 GPM at lower pressures suitable for lighter-duty jobs. It emphasizes portability with a compact 16.5- to 26-inch profile and easy maneuverability via its wheels. The onboard soap tank and included nozzle set expand its utility for general cleaning around homes, vehicles, and outdoor spaces, while ensuring a straightforward setup for casual users.
JEGS 5-Gallon Portable Parts Washer
The JEGS parts washer is designed for small parts cleaning and degreasing, with a max pump output of 3.96 GPM. Its compact steel construction and removable tray enhance usability for hobbyist shops and light industrial setups. While not a traditional pressure washer for exterior surfaces, it delivers high flow for flushing and cleaning intricate components, radiators, bearings, and other small parts. The unit’s portability supports easy relocation within a workshop or garage.
Kärcher Multi-Purpose Pressure Washer Detergent
While not a washer by itself, this highly concentrated detergent from Kärcher is designed to work with compatible pressure washers and can yield up to 20 gallons of cleaner from a single gallon of concentrate. It supports efficient cleaning on concrete, pavement, driveways, patios, siding, and other surfaces when paired with an appropriate GPM-rated washer. For users prioritizing detergent efficiency and wide compatibility, it offers a practical option to complement high-GPM machines.
Westinghouse WPX2700 Onboard-Suds Ready
This entry highlights soap compatibility in a high-GPM context. The unit’s onboard soap tank supports efficient cleaning with included foam and detergent options, enabling thorough cleaning of furniture, fences, and outdoor surfaces without frequent trips for detergents. Soap integration is particularly useful for tackling grease and grime in outdoor spaces, vehicles, and painted surfaces when paired with appropriate pressure settings.
Buying Guide
- GPM vs. PSI: For faster cleaning of large surfaces, prioritize higher GPM, but ensure your pressure rating (PSI) matches the job. A balance between PSI and GPM yields best overall performance for decks, siding, and driveways.
- Power source: Gas-powered washers typically offer higher GPM and rugged performance for frequent, heavy-duty use, while electric models are quieter, lighter, and easier to maintain for home use.
- Portability and storage: Consider unit dimensions, weight, wheels, and handle design. Smaller profiles with wheels are easier to store and move around a garage or yard.
- Detergent compatibility: If you plan to use cleaning solutions, ensure the soap tank integration or compatible detergents work with your washer’s design and spray patterns.
- Maintenance and parts availability: Look for models with readily available replacement parts (nozzles, pumps, seals) and clear maintenance guidelines to maximize lifespan.
- Intended surfaces: Heavy-duty concrete and brick surfaces demand higher PSI and robust pumps, while delicate surfaces like vinyl siding or cars require gentler settings and appropriate nozzles.
- Accessory compatibility: A broad nozzle set, foam cannons, and onboard soap tanks enhance versatility. Ensure compatibility with existing hoses and fittings you already own.
