Zoom on the WEN PW21
The WEN PW21, a medium duty pressure washer, gives its user an all-around versatile cleaning experience, topped off by the following features:
- spot cleaning of hard, paint-free surfaces and out-of-reach areas
- intense cleaning of hard, unpainted surfaces
- cleaning of painted and frail surfaces
- use of detergent and cleaning solutions
Powered by a 14.5 amp universal motor, its axial (wobble plate) pump can deliver a pressure of 2030 PSI (around 34 times more than a standard garden hose) and a flow of up to 1.76 GPM (values claimed by the manufacturer). Combined, these values mean that the WEN PW21 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.
Because the device weighs just 28 lbs, carrying it around is very easy. This is, in part, thanks to its plastic frame, which allows it to remain as lightweight as possible. On top of its light weight, the transportability and ease of use of this model is further improved by the addition of two 6" never-flat wheels.
Along with the WEN PW21 itself, the package also includes a spray gun, a wand, a pressure hose, 5 nozzles and a detergent injection feature, which are discussed in further detail below.
- Soap injection: Detergent is stored in a removable 0.32 gal tank. The detergent dilution ratio is selected manually, via a dedicated dial. If a soap nozzle is attached, the device will proceed to add the detergent to the water automatically.
- Pressure hose: The included 20 ft high-pressure hose can be neatly stored on the unit when idle thanks to a convenient hose reel, which also improves its lifespan.
- Spray gun and wand: The included classic ergonomic spray gun and its wand can be easily 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.
