The Westinghouse WPX3100 is a gas-powered pressure washer offering a maximum water pressure of 3100 PSI and flow of 2.5 GPM. (Read full specs)
Zoom on the Westinghouse WPX3100
The Westinghouse WPX3100 is a heavy duty, commercial pressure washer, that provides its users with an all-around versatile cleaning experience, and enables:
- spot cleaning of hard, paintless surfaces and reaching far-away areas
- intense cleaning of tough, paintless surfaces
- cleaning of painted and fragile surfaces
- applying detergent and cleaning solutions
With an impressive 208 cc (5.7 hp) engine, its brass axial cam pump delivers a pressure of 3100 PSI (roughly 52 times more than a standard garden hose) and a flow of up to 2.5 GPM (values claimed by the manufacturer), resulting in the Westinghouse WPX3100's cleaning power of 7750 Cleaning Units.
A classic pull-start mechanism is responsible for starting the gas-powered pressure washer’s Westinghouse engine.
The fuel is stored in a tank, which can hold up to 0.9 gallon of gasoline.
Design & Handling
Thanks to its hand truck design and approximate dimensions of L24 x W19 x H42 in, the Westinghouse WPX3100 offers great mobility. 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.
Most users can maneuver this model easily, as it weighs just 66 lbs. A major component of its weight are its 208 cc Westinghouse engine and steel tubing frame. The WPX3100 can still be easily manipulated and maneuvered, thanks to its two 12" never-flat wheels.
Along with the Westinghouse WPX3100 itself, the package also includes a spray gun, a pressure hose, 5 nozzles and a detergent injection feature, which are discussed in further detail below.
- Soap injection: Detergent is stored in 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. The detergent will be added automatically to the water when a soap nozzle is attached.
- Pressure hose: The 30 ft ⌀5/16" high-pressure hose (3100 PSI rating), which is included with the device, can be stored neatly on the unit itself when idle, using a set of convenient hooks.
- Spray gun: A side hook allows for an easy storage of the included ergonomic EnduraGrasp spray gun.
- Nozzles: The following table illustrates the 5 included nozzles, along with the surfaces which they are the most suitable for.

The Westinghouse WPX3100's performance versus other pressure washers
The following charts are provided to give you an idea of how the key specs of the Westinghouse WPX3100 compare to similarly priced pressure washers.
- With a maximum pressure output of 3100 PSI, the Westinghouse WPX3100 finds itself in the expected pressure range among gas-powered units that cost between $300 and $400. If you're going after the highest possible power of the water stream, one of the best in this price range is the Westinghouse WPX3400 that can reach up to 3400 PSI.
- The water flow of this washer, which reaches up to 2.5 GPM (gallons per minute) is one of the higher values found in the above-mentioned price range. If you’re after the highest rinsing efficiency, one of the units with the highest water flow in the current price range is the Predator 3100, that can deliver up to 2.8 GPM.
- Reaching up to 7750 Cleaning Units (PSI x GPM), the WPX3100 is one of the more efficient amongst its similarly priced peers. When it comes to the highest overall cleaning power in the current price range, one of the products at the very top currently is the Predator 3200 and its 8960 Cleaning Units.
