Zoom on the WEN PW21
In a nutshell, the WEN PW21 is a medium duty 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 and frail surfaces
- applying 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.
As it is an electric pressure washer, the motor of the PW21 gets easily started by a simple 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.
Standing at only 28 lbs, this model can be carried around very easily. Among other factors, the plastic frame plays a role in this light weight. As if this lightweight wasn't enough, the device also features two 6" never-flat wheels to further improve its ease of use and of transport.
The WEN PW21'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: 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. The detergent is automatically added to the water when a soap nozzle is connected.
- 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: Both the classic ergonomic spray gun and its wand may be conveniently stored in a side hook.
- Nozzles: The table below shows you the 5 included nozzles, as well as the surfaces they're the most appropriate for.

- 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 $210 price range. As for the device with the most powerful water stream, in this price range, one of the top products is the Sun Joe SPX3000-MAX with 2800 PSI.
- The water flow of this washer, which reaches up to 1.76 GPM (gallons per minute) is one of the highest values found in the above-mentioned price range.
- The PW21, with its 3572.8 Cleaning Units (PSI x GPM) sits at the high end of the cleaning efficiency spectrum, when compared to other devices of similar price. If the highest overall cleaning power is your top priority, the Realm BY02-BIMK, which can reach up to 4550 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 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.
