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, paintless surfaces and reaching far-away areas
- thorough cleaning of hard, paint-free surfaces
- cleaning of painted and frail surfaces
- application 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.
Since it is an electric pressure washer, the motor of the PW21 is started simply 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.
Since the unit weighs only 28 lbs, it is very easily carried around. 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 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: Detergent is stored in 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: A neat storage for the included 20 ft high-pressure hose is facilitated by a convenient hose reel, which also improves its lifespan.
- Spray gun and wand: A side hook allows for an easy storage of the included classic ergonomic spray gun and its wand.
- Nozzles: The 5 nozzles included with the device, and the respective surfaces which they’re the most suitable for, are shown in the following table.
