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
In a nutshell, the Westinghouse WPX3100 is a heavy duty, commercial pressure washer, which not only offers an all-around versatile cleaning experience, but that also allows:
- spot cleaning of hard, paint-free surfaces and out-of-reach areas
- 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.
Gasoline is stored in a fuel tank with a maximum capacity of 0.9 gallon.
Design & Handling
The Westinghouse WPX3100 is very mobile, due to its hand truck design and approximate dimensions of L24 x W19 x H42 in. The robust and sturdy steel tubing frame offers longevity to the assembly. The foam-padded fixed handle adds to the WPX3100 convenience of transport, while offering a comfortable grip.
With a weight of 66 lbs, the unit can be easily maneuvered by most users. A major component of its weight are its 208 cc Westinghouse engine and steel tubing frame. But, as the WPX3100 does have a set of two 12" never-flat wheels, it can be easily maneuvered and manipulated.
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. The detergent is automatically added to the water when a soap nozzle is connected.
- Pressure hose: A neat storage for the included 30 ft ⌀5/16" high-pressure hose (3100 PSI rating) is facilitated by 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 included nozzles, and the respective surfaces they’re appropriate for, are listed in the table below.

- Onboard storage: The Westinghouse WPX3100's handy storage area lets you store nozzles and accessories, and thus, you’ll be always prepared and have everything necessary for the job at hand.
- Safety: Safety of operation is enhanced by a thermal relief valve (which helps to prevent internal pump damage) and a trigger lock mechanism (which prevents accidental operation).
- Accessories: Besides the usual owner's manual (opens in a new tab) and documentation to get you promptly started, the Westinghouse WPX3100 comes with tool kit, spray gun, nozzle cleaner, funnel, pressure hose and oil.
- Emissions: The Westinghouse WPX3100 is EPA-approved and CARB-compliant. And so, this pressure washer is available for sale and purchase in any of the 50 states, including California.
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.
- The Westinghouse WPX3100, with a maximum pressure output of 3100 PSI, has an average pressure output, when considering gas-powered units in $300 to $400 price range. If your priority is the highest possible power of the water stream, in this price range, we suggest checking out the Stanley SXPW3425, which reaches up to 3400 PSI.
- In its respective price range, the water flow of this washer, 2.5 GPM (gallons per minute), ranks as average. If rinsing away debris most efficiently is your priority, one of the devices with the highest GPM in this price range is the Lifan LFQ3370, which can reach up to 3 GPM.
- With the WPX3100's 7750 Cleaning Units (PSI x GPM), its cleaning efficiency range may be considered average, compared to gas-powered units of similar price. If you consider the highest overall cleaning power as a really important factor, the Lifan LFQ3370 and its 9900 Cleaning Units has one of the highest cleaning efficiency of all the similarly priced units.
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.
