Zoom on the Westinghouse WPX3400

In summary, the Westinghouse WPX3400 is a heavy duty, commercial pressure washer, that offers an all-around versatile cleaning experience, and also:

  • spot cleaning of hard, unpainted surfaces and high-reach cleaning
  • intense cleaning of hard, unpainted surfaces

Ahead are presented its power characteristics and design, its main features and any other additional features.

Power

The Westinghouse WPX3400 in use

The Westinghouse WPX3400

Powered by a powerful 212 cc engine, its axial cam pump can deliver a pressure of 3400 PSI (around 57 times more than a standard garden hose) and a flow of up to 2.6 GPM (values claimed by the manufacturer). Combined, these values mean that the Westinghouse WPX3400 has a cleaning power of 8840 Cleaning Units.

This gas-powered pressure washer’s engine is started by a traditional pull-start mechanism.

The fuel is stored in a tank, which can hold up to 0.9 gallon of gasoline.

Design & Handling

Thanks to its hand truck design and approximate dimensions of D21 x W19.5 x H39 in, the Westinghouse WPX3400 offers great mobility. Its sturdy steel tubing frame provides longevity to the assembly. 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. Its 212 cc engine and steel tubing frame all add up to a substantial part of that weight. However, the two 12" never-flat wheels allow the WPX3400 to be easily manipulated and maneuvered.

Main Features

The Westinghouse WPX3400

The Westinghouse WPX3400'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 0.5 gal tank. The Westinghouse WPX3400 includes an automatic soap dilution mechanism, which will dilute the detergent using a 12:1 ratio. Whenever a soap nozzle is connected, the detergent is automatically added to the water.
  • Pressure hose: The 25 ft ⌀5/16" high-pressure hose, which is included with the device, can be stored neatly on the unit itself when idle, using a set of convenient hooks.
  • Spray gun and wand: The included classic ergonomic spray gun and its steel wand can be easily stored in a side hook.
  • 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.
