Description
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:
- focused spot cleaning on hard, unpainted surfaces, accessing high spots, and efficiently eliminating stubborn stains
- complete cleaning of hard surfaces, vehicle washing, and surface prep for painting
- mild cleaning for delicate surfaces, and low-pressure cleaning for broader areas
- applying detergent and cleaning solutions, and rinsing surfaces
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
The Westinghouse WPX3800's brass triplex pump, powered by a powerful 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). Thus, the Westinghouse WPX3800 achieves 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
With its wheelbarrow design, the Westinghouse WPX3800 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.
With its hefty 91 lbs, this unit isn't exactly easy to handle, making manual lifting and transport quite a daunting task, especially on uneven terrain. The major reasons for its heavy weight are its 274cc engine, the triplex pump and steel tubing frame. Despite this, the presence of two 10" 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 ensured by a 0.8 gal tank. The detergent is diluted with a 12:1 ratio by the Westinghouse WPX3800's automatic soap dilution mechanism. Upon attaching a soap nozzle, the pressure washer seamlessly integrates the detergent into the water flow.
- Pressure hose: With a set of convenient hooks, the unit offers a practical solution for maintaining workspace order, allowing the included 35 ft ⌀5/16" high-pressure hose to be neatly stored when idle.
- Spray gun and wand: Both the classic ergonomic spray gun and its steel wand may be conveniently stored in a side hook.
- Nozzles: Below, you'll find a table outlining the 5 included nozzles and their recommended surfaces.
