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 or delicate surfaces
- use of detergent and cleaning solutions
Using a 14.5 amp universal motor, its axial (wobble plate) pump delivers a pressure of up to 2030 PSI (roughly 34 times more than a standard garden hose) and a flow of up to 1.76 GPM (values claimed by the manufacturer). Together, the values result in a cleaning power of 3572.8 Cleaning Units.
Being an electric pressure washer, the WEN PW21's motor can be easily started by a convenient 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.
With a weight of only 28 lbs, the unit is very easy to carry around. It is lightweight, partly thanks to its plastic frame. A set of two 6" never-flat wheels also improves the ease of transport of the device.
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: A safe detergent storage is facilitated by a removable 0.32 gal tank. The detergent dilution ratio is selected manually, via a dedicated dial. The detergent is automatically added to the water when a soap nozzle is connected.
- Pressure hose: The 20 ft high-pressure hose, which is included with the device, can be stored neatly on the unit itself when idle, using a convenient hose reel, which also improves its lifespan.
- Spray gun and wand: A side hook enables you to easily store 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.
