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, unpainted surfaces and high-reach cleaning
- intense cleaning of tough, paintless surfaces
- cleaning of painted or delicate surfaces
- use of detergent and cleaning solutions
Powered by an impressive 208 cc (5.7 hp) engine, its brass axial cam pump can deliver a pressure of 3100 PSI (around 52 times more than a standard garden hose) and a flow of up to 2.5 GPM (values claimed by the manufacturer). Combined, these values mean that the Westinghouse WPX3100 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. The strong steel tubing frame assures assembly longevity. The foam-padded fixed handle adds to the WPX3100 convenience of transport, while offering a comfortable grip.
The majority of users will be able to maneuver this unit easily, it only weighs 66 lbs. Its 208 cc Westinghouse engine and steel tubing frame account for a good chunk of that weight. Nethertheless, thanks to its two 12" never-flat wheels, the WPX3100 remains very easy to manipulate and maneuver.
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 storage is ensured by a 1 gal tank. The Westinghouse WPX3100 is not equipped with a soap dilution mechanism, and thus, it is up to the user to ensure the detergent’s correct dilution ratio when using it. If a soap nozzle is attached, the device will proceed to add the detergent to the water automatically.
- Pressure hose: The included 30 ft ⌀5/16" high-pressure hose (3100 PSI rating) can be neatly stored on the unit when idle thanks to a set of convenient hooks.
- Spray gun: A side hook allows for an easy storage of the included ergonomic EnduraGrasp spray gun.
- 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.

- With its 3100 PSI max pressure output, the Westinghouse WPX3100 is in the expected pressure range, for gas-powered units in the $300-400 price range. In case you are looking for a device with the highest possible power of its water stream, one of the top achievers in this price range is the Westinghouse WPX3400 with a PSI of 3400.
- In the aforementioned price range, the GPM (gallons per minute) of this washer, which can reach 2.5, can be considered in the average. If being able to rinse away debris as efficiently as possible is your priority, one of the products with the highest GPM in this price range is the Predator 3100, with 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. If you are after the highest overall cleaning power, the Westinghouse WPX3400 with its 8840 Cleaning Units is one of the products that can achieve the highest cleaning efficiency in this price range.
As you can see from this interactive chart, when compared to other gas-powered washers between 7500 and 8000 Cleaning Units, the Westinghouse WPX3100 is on the average side of the price range.
Therefore, this pressure washer nicely fits in the expected budget for this kind of cleaning power.
