Zoom on the Westinghouse WPX3400
The Westinghouse WPX3400 is a heavy duty, commercial pressure washer, that provides its users with an all-around versatile cleaning experience, and enables:
- spot cleaning of hard, unpainted surfaces and high-reach cleaning
- intense cleaning of hard, unpainted surfaces
- cleaning of painted or delicate surfaces
- use of detergent and cleaning solutions
With an impressive 212cc engine, its axial cam pump delivers a pressure of 3400 PSI (roughly 57 times more than a standard garden hose) and a flow of up to 2.6 GPM (values claimed by the manufacturer), resulting in the Westinghouse WPX3400's cleaning power of 8840 Cleaning Units.
This gas-powered pressure washer’s engine is started by a traditional pull-start mechanism.
Gasoline storage is facilitated by a fuel tank with a maximum capacity of 0.9 gallon.
Design & Handling
The Westinghouse WPX3400 is very mobile, due to its hand truck design and approximate dimensions of D21 x W19.5 x H39 in. The strong steel tubing frame assures assembly longevity. The foam-padded fixed handle adds to the WPX3400 convenience of transport, while offering a comfortable grip.
With a weight of 63 lbs, the unit can be easily maneuvered by most users. A major component of its weight are its 212cc engine and steel tubing frame. However, the two 12" never-flat wheels allow the WPX3400 to be easily manipulated and maneuvered.
The Westinghouse WPX3400 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 0.5 gal tank. The Westinghouse WPX3400 features an automatic soap dilution mechanism, that will dilute your detergent with a 12:1 ratio. The detergent is automatically added to the water when a soap nozzle is connected.
- Pressure hose: The included 25 ft ⌀5/16" high-pressure hose can be neatly stored on the unit when idle thanks to a set of convenient hooks.
- Spray gun and wand: A side hook enables you to easily store the included classic ergonomic spray gun and its wand.
