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, a heavy duty, commercial pressure washer, gives its user an all-around versatile cleaning experience, topped off by the following features:
- spot cleaning of hard, unpainted surfaces and high-reach cleaning
- intense cleaning of hard, unpainted surfaces
- cleaning of painted and fragile surfaces
- applying detergent and cleaning solutions
The WEN PW3100's axial cam pump, powered by a powerful 208 cc 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 WEN PW3100 thus has a cleaning power of 7750 Cleaning Units.
The engine of this gas-powered pressure washer gets started by a classic pull-start mechanism.
Gasoline is stored in a fuel tank with a maximum capacity of 0.9 gallon.
Design & Handling
The WEN PW3100 is very mobile, due to its hand truck design and approximate dimensions of D26 x W19.5 x H39.5 in. The strong steel frame assures assembly longevity. 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 account for a good chunk of that weight. The PW3100 can still be easily manipulated and maneuvered, thanks to its two 12" never-flat wheels.
The WEN PW3100 comes with a spray gun, a wand, a pressure hose, 5 nozzles and a detergent injection feature, which are detailed below.
- Soap injection: A safe detergent storage is facilitated by 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 30 ft ⌀5/16" high-pressure hose, which is included with the device, can be stored neatly on the unit itself when idle, using a set of convenient hooks.
- Spray gun and wand: The included classic ergonomic spray gun and its stainless steel wand can be easily stored in a side hook.
- Nozzles: The 5 included nozzles, and the respective surfaces they’re appropriate for, are listed in the table below.

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.
- With a maximum pressure output of 3100 PSI, the WEN PW3100 finds itself in the expected pressure range among gas-powered units that cost between $300 and $400. 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 its water flow, this washer, with a GPM (gallons per minute) of 2.5 is in the average compared to other devices in its price range. If maximum rinsing efficiency is your top priority, one of the devices with the highest water flow in the same price range is the Lifan LFQ3370, with a GPM of 3.
- With the PW3100's 7750 Cleaning Units (PSI x GPM), its cleaning efficiency range may be considered average, compared to gas-powered units of similar price. If the highest overall cleaning power is your top priority, the Lifan LFQ3370, which can reach up to 9900 Cleaning Units, is one of the most efficient of the devices in the current price range.
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.
