Zoom on the Westinghouse WPX3100
In summary, the Westinghouse WPX3100 is a heavy duty, commercial pressure washer, that offers an all-around versatile cleaning experience, and also:
- spot cleaning of hard, paint-free surfaces and out-of-reach areas
- intense cleaning of hard, unpainted surfaces
- cleaning of painted and fragile surfaces
- use of detergent and cleaning solutions
The Westinghouse WPX3100's brass axial cam pump, powered by a powerful 208 cc (5.7 hp) engine, can provide a pressure of up to 3100 PSI (approximately 52 times more than a standard garden hose) and a flow of up to 2.5 GPM (values claimed by the manufacturer). The Westinghouse WPX3100 thus has a cleaning power of 7750 Cleaning Units.
The Westinghouse engine of this gas-powered pressure washer relies on an old-school pull-start mechanism to get started.
The fuel is stored in a tank, which can hold up to 0.9 gallon of gasoline.
Design & Handling
The Westinghouse WPX3100 offers superb mobility, with a hand truck design and approximate dimensions of L24 x W19 x H42 in. Its sturdy steel tubing frame provides longevity to the assembly. The foam-padded fixed handle adds to the WPX3100 convenience of transport, while offering a comfortable grip.
Weighing 66 lbs, the unit is easy to maneuver by most people. One of the largest contributors to its weight are its 208 cc Westinghouse engine and its steel tubing frame. The WPX3100 can still be easily manipulated and maneuvered, thanks to its two 12" never-flat wheels.
The Westinghouse WPX3100's package includes a spray gun, a pressure hose, 5 nozzles and a detergent injection feature, with a more detailed description below.
- Soap injection: Detergent storage is ensured by a 1 gal tank. However, since the Westinghouse WPX3100 does not feature a soap dilution mechanism, you'll have to make sure your detergent is correctly diluted before use. If a soap nozzle is attached, the device will proceed to add the detergent to the water automatically.
- Pressure hose: Using a set of convenient hooks, the included 30 ft ⌀5/16" high-pressure hose (3100 PSI rating) can be easily stored on the unit when it is not running.
- Spray gun: The included ergonomic EnduraGrasp spray gun can be easily stored in a side hook.
- Nozzles: The 5 nozzles included with the device, and the respective surfaces which they’re the most suitable for, are shown in the following table.
