  • spot cleaning of hard, unpainted surfaces, reaching high areas, and removing stubborn stains
  • complete cleaning of hard surfaces, vehicle washing, and surface prep for painting
  • delicate surface cleaning, andbroad area cleaning with reduced pressure
  • applying detergents or chemicals, and rinsing surfaces afterward

Its power characteristics and design, its main features and all its additional features are presented ahead.

Power

The Westinghouse WPX4400 in use

The Westinghouse WPX4400

Powered by a powerful 420cc engine, its brass triplex pump can deliver a pressure of 4400 PSI (around 73 times more than a standard garden hose) and a flow of up to 4.2 GPM (values claimed by the manufacturer). With these values combined, the Westinghouse WPX4400 boasts a cleaning power of 18480 Cleaning Units.

The engine of this gas-powered pressure washer is initiated by a classic pull-start mechanism.

Containing gasoline, the pressure washer's fuel tank can hold a maximum of 1.72 gallon.

Design & Handling

With its wheelbarrow design, the Westinghouse WPX4400 delivers superior maneuverability and stability, facilitating easy transport and steady performance across various surfaces. The durable steel tubing frame of the assembly ensures its longevity, providing stability and shielding internal components from damage, even in tough conditions. The reversible handle offers further versatility, as its different positions make the unit less bulky when stored.

At 142 lbs, this unit's substantial weight makes it quite a challenge for users to lift and maneuver, particularly on uneven surfaces where its heft can become even more apparent. The major reasons for its heavy weight are its 420cc engine, the triplex pump and steel tubing frame. However, the incorporation of two 12" never-flat wheels makes navigating the WPX4400 less cumbersome, even on uneven terrain.

Main Features

The Westinghouse WPX4400 in use

The Westinghouse WPX4400

The Westinghouse WPX4400'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: Even without a built-in soap tank, the device relies on a siphon hose to provide detergent. The detergent is diluted with a 12:1 ratio by the Westinghouse WPX4400's automatic soap dilution mechanism. When a soap nozzle is connected, the pressure washer takes the initiative to mix the detergent with the water flow automatically.
  • Pressure hose: The unit comes equipped with an included 50 ft ⌀5/16" high-pressure hose, which can be neatly stored on the unit when idle, thanks to a set of convenient hooks, ensuring easy access and organization.
  • Spray gun and wand: The included ergonomic EnduraGrasp spray gun and its steel wand can be easily stored in a side hook.
  • Nozzles: The following table provides information on the 5 included nozzles and their recommended surface uses.
