Zoom on the WEN PW21
The WEN PW21 is a medium duty pressure washer, that provides its users with an all-around versatile cleaning experience, and enables:
- spot cleaning of hard, paint-free surfaces and out-of-reach areas
- intense cleaning of tough, paintless surfaces
- cleaning of painted or delicate surfaces
- application of detergent and cleaning solutions
The WEN PW21's axial (wobble plate) pump, powered by a 14.5 amp motor, can provide a pressure of up to 2030 PSI (approximately 34 times more than a standard garden hose) and a flow of up to 1.76 GPM (values claimed by the manufacturer). The WEN PW21 thus has a cleaning power of 3572.8 Cleaning Units.
The PW21 is an electric pressure washer and thus, can be easily started by an ON/OFF switch. The unit is ready-to-use with peace of mind, thanks to the included 36 ft GFCI cord.
Design & Handling
With its portable design and approximate dimensions of D15.4 x W13.9 x H35.5 in, the WEN PW21 makes mobility one of its core strengths. The handle adds to the PW21 convenience of transport.
Because the device weighs just 28 lbs, carrying it around is very easy. It is lightweight, partly thanks to its plastic frame. On top of its light weight, the transportability and easy of use of this model is further improved by the addition of two 6" never-flat wheels.
The WEN PW21 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 removable 0.32 gal tank. The unit features a dial to allow you to manually choose the detergent dilution ratio. Whenever a soap nozzle is connected, the detergent is automatically added to the water.
- Pressure hose: Using a convenient hose reel, which also improves its lifespan, the included 20 ft high-pressure hose can be easily stored on the unit when it is not running.
- Spray gun and wand: A side hook enables you to easily store the included classic ergonomic spray gun and its wand.
- Nozzles: The following table illustrates the 5 included nozzles, along with the surfaces which they are the most suitable for.

The WEN PW21's performance versus other pressure washers
The following charts are provided to give you an idea of how the key specs of the WEN PW21 compare to similarly priced pressure washers.
- Reaching a 2030 PSI max pressure output, the WEN PW21 has an expected pressure value, compared to the other electric units in the $150 to $200 price range. If you're going after the highest possible power of the water stream, one of the best in this price range is the Realm BY02-BIMK that can reach up to 2600 PSI.
- In the aforementioned price range, the 1.76 GPM (gallons per minute) of this washer makes it one of the best performing units in terms of the delivered volume of water.
- Boasting with 3572.8 Cleaning Units (PSI x GPM), the PW21 is one of the more efficient devices in its respective price range. If you consider the highest overall cleaning power as a really important factor, the Realm BY02-BIMK and its 4550 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 electric washers between 3500 and 4000 Cleaning Units, the WEN PW21 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.
