Zoom on the Westinghouse WPX3800
In a nutshell, the Westinghouse WPX3800 is a heavy duty, commercial pressure washer, which not only offers an all-around versatile cleaning experience, but that also allows:
- spot cleaning of hard, unpainted surfaces and high-reach cleaning
- intense cleaning of tough, paintless surfaces
- cleaning of painted or delicate surfaces
- application of detergent and cleaning solutions
The Westinghouse WPX3800's brass triplex pump, powered by an impressive 274cc engine, can provide a pressure of up to 3800 PSI (approximately 63 times more than a standard garden hose) and a flow of up to 3.6 GPM (values claimed by the manufacturer). The Westinghouse WPX3800 thus has a cleaning power of 13680 Cleaning Units.
The engine of this gas-powered pressure washer gets started by a classic pull-start mechanism.
Gasoline is stored in a fuel tank with a maximum capacity of 1.32 gallon.
Design & Handling
The wheelbarrow design of the Westinghouse WPX3800 grants mobility and stability to the unit. Its sturdy steel tubing frame provides longevity to the assembly. The reversible handle offers further versatility, as its different positions make the unit less bulky when stored.
At 91 lbs, we can't really say that the unit is a lightweight, and manually lifting or transporting it could be a challenge. A key role in its final weight is played by its 274cc engine, the triplex pump and steel tubing frame. However, the device’s two 10" wheels play a key role in its maneuverability, as they allow it to be manipulated smoothly.
The Westinghouse WPX3800'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: Detergent is stored in a 0.8 gal tank. The detergent is diluted with a 12:1 ratio by the Westinghouse WPX3800's automatic soap dilution mechanism. The detergent will be added automatically to the water when a soap nozzle is attached.
- Pressure hose: A neat storage for the included 35 ft ⌀5/16" high-pressure hose is facilitated by 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 steel wand.
- Nozzles: The following table illustrates the 5 included nozzles, along with the surfaces which they are the most suitable for.
