Description
Zoom on the Westinghouse WPX3800
The Westinghouse WPX3800 is a heavy duty, commercial pressure washer, that provides its users with an all-around versatile cleaning experience, and enables:
- targeted spot cleaning for hard, unpainted surfaces, reaching elevated areas, and thoroughly removing stubborn stains
- overall cleaning of hard surfaces, washing vehicles, and prepping surfaces for painting
- soft cleaning of delicate surfaces, and gentle cleaning for larger areas with low pressure
- applying detergents or chemicals, and rinsing surfaces afterward
The following sections will present you in detail its power characteristics and design, its main features and all the additional features it has to offer.
Power
The Westinghouse WPX3800
Powered by a powerful 274cc engine, its brass triplex pump can deliver a pressure of 3800 PSI (around 63 times more than a standard garden hose) and a flow of up to 3.6 GPM (values claimed by the manufacturer). With these values combined, the Westinghouse WPX3800 boasts a cleaning power of 13680 Cleaning Units.
For this gas-powered pressure washer, the engine is started using a time-tested pull-start mechanism.
Containing gasoline, the pressure washer's fuel tank can hold a maximum of 1.32 gallon.
Design & Handling
Featuring a wheelbarrow design, the Westinghouse WPX3800 prioritizes maneuverability and stability, ensuring smooth handling and reliable functionality in demanding cleaning applications. Guaranteeing longevity, the robust steel tubing frame offers stability and protects internal components, even when subjected to demanding tasks. The reversible handle offers further versatility, as its different positions make the unit less bulky when stored.
At 91 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. A key role in its final weight is played by its 274cc engine, the triplex pump and steel tubing frame. Despite this, the presence of two 10" never-flat wheels reduces the complexity of moving the WPX3800, even on rugged surfaces.
Main Features
Along with the Westinghouse WPX3800 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: Detergent storage is facilitated by the inclusion of a 0.8 gal tank. The Westinghouse WPX3800 includes an automatic soap dilution mechanism, allowing detergent to be diluted to the ratio of 12:1 with ease. The detergent is automatically mixed with the water flow by the pressure washer when a soap nozzle is connected.
- Pressure hose: The unit comes equipped with an included 35 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 classic ergonomic spray gun and its steel wand can be easily stored in a side hook.
- Nozzles: Refer to the table below for details on the 5 included nozzles and their recommended surface applications.

- Safety: Safety of operation is enhanced by a thermal relief valve (which helps to prevent internal pump damage) and a trigger lock mechanism (which prevents accidental operation).
- Accessories: Besides the usual owner's manual (opens in a new tab) and documentation to get you promptly started, the Westinghouse WPX3800 comes with funnel, spray gun, wand, oil, nozzle cleaner and pressure hose.
