The WEN PW3100 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 WEN PW3100
The WEN PW3100 is a heavy duty, commercial pressure washer, that provides its users with an all-around versatile cleaning experience, and enables:
- spot cleaning of hard, unpainted surfaces and high-reach cleaning
- intense cleaning of tough, paintless surfaces
- cleaning of painted and frail surfaces
- use of detergent and cleaning solutions
Its axial cam pump, which utilizes a powerful 208 cc engine, may deliver a pressure of up to 3100 PSI (almost 52 times more than a standard garden hose) and a flow of up to 2.5 GPM. These values correspond to a cleaning power of 7750 Cleaning Units.
A classic pull-start mechanism is responsible for starting the gas-powered pressure washer’s engine.
Gasoline is stored in a fuel tank with a maximum capacity of 0.9 gallon.
Design & Handling
The WEN PW3100 offers superb mobility, with a hand truck design and approximate dimensions of D26 x W19.5 x H39.5 in. Its sturdy steel frame provides longevity to the assembly. The rubber-padded handle adds to the PW3100 convenience of transport, while offering a comfortable grip.
Weighing 67 lbs, the unit is easy to maneuver by most people. Its 208 cc engine and steel frame all add up to a substantial part of that weight. However, the two 12" never-flat wheels allow the PW3100 to be easily manipulated and maneuvered.
The WEN PW3100's package includes a spray gun, a wand, a pressure hose, 5 nozzles and a detergent injection feature, with a more detailed description below.
- Soap injection: Detergent is stored in a 0.25 gal tank. The WEN PW3100 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. When a soap nozzle is connected, the detergent will be added automatically to the water.
- Pressure hose: The included 30 ft ⌀5/16" high-pressure hose can be neatly stored on the unit when idle thanks to a set of convenient hooks.
- Spray gun and wand: A side hook enables you to easily store the included classic ergonomic spray gun and its stainless steel wand.
- Nozzles: The table below shows you the 5 included nozzles, as well as the surfaces they're the most appropriate for.

The WEN PW3100's performance versus other pressure washers
The following charts are provided to give you an idea of how the key specs of the WEN PW3100 compare to similarly priced pressure washers.
- Reaching a 3100 PSI max pressure output, the WEN PW3100 has an expected pressure value, compared to the other gas-powered units in the $300 to $400 price range. If the highest possible power of the water stream is your priority, one of the champions in this price range is the Stanley SXPW3425 with 3400 PSI.
- Considering the above-mentioned price range, this washer's maximum water flow of 2.5 GPM (gallons per minute) is higher than the average. 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.
- As the PW3100 has a total of 7750 Cleaning Units (PSI x GPM), it finds itself in the average cleaning efficiency range for similarly priced gas-powered units. In case you are looking for the highest overall cleaning power, in this price range, one of the current champions is the Briggs & Stratton 20505 and its 9520 Cleaning Units.
As you can see from this interactive chart, when compared to other gas-powered washers between 7500 and 8000 Cleaning Units, the WEN PW3100 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.
