Power
The Westinghouse WPX3800
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). Thus, the Westinghouse WPX3800 achieves a cleaning power of 13680 Cleaning Units.
The engine of this gas pressure washer is activated by pulling a starter cord, following a traditional approach.
Fuel for the pressure washer is housed in a tank capable of holding up to 1.32 gallon of gasoline.
Design & Handling
Designed with a wheelbarrow configuration, the Westinghouse WPX3800 ensures improved mobility and stability, allowing for effortless movement and reliable operation on challenging surfaces. The robust steel tubing frame guarantees longevity of the assembly, providing stability and protection for internal components, even under demanding working conditions. The reversible handle offers further versatility, as its different positions make the unit less bulky when stored.
Weighing in at 91 lbs, it's safe to say this unit isn't lightweight, which might pose difficulties for users when it comes to lifting and transporting, particularly over uneven surfaces. Its 274cc engine, the triplex pump and steel tubing frame are mainly responsible for its heavy weight. Nonetheless, the addition of two 10" never-flat wheels simplifies maneuvering the WPX3800, even across rough ground.
Main Features
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: The pressure washer comes equipped with a 0.8 gal tank to store detergent. The Westinghouse WPX3800 features an automatic soap dilution mechanism that dilutes detergent according to a predefined ratio of 12:1. Upon attaching a soap nozzle, the pressure washer seamlessly integrates the detergent into the water flow.
- Pressure hose: Utilizing a set of convenient hooks, the unit offers a convenient solution for storing the included 35 ft ⌀5/16" high-pressure hose when it's not in use, keeping it neatly organized.
- Spray gun and wand: Both the classic ergonomic spray gun and its steel wand may be conveniently stored in a side hook.
- Nozzles: In the table below, you can see the 5 included nozzles alongside their respective recommended surface uses.
