Description
Zoom on the Westinghouse WPX4400
The Westinghouse WPX4400, a commercial pressure washer, gives its user an all-around versatile cleaning experience, topped off by the following features:
- pinpoint spot cleaning of hard, unpainted surfaces, accessing high areas, and successfully 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 and cleaning agents, and rinsing off surfaces
Ahead are presented its power characteristics and design, its main features and any other additional features.
Power
The Westinghouse WPX4400
With an impressive 420cc engine, its brass triplex pump delivers a pressure of 4400 PSI (roughly 73 times more than a standard garden hose) and a flow of up to 4.2 GPM (values claimed by the manufacturer), resulting in the Westinghouse WPX4400's cleaning power of 18480 Cleaning Units.
To initiate the engine of this gas-powered pressure washer, a traditional pull-start mechanism is employed.
Containing gasoline, the pressure washer's fuel tank can hold a maximum of 1.72 gallon.
Design & Handling
The Westinghouse WPX4400's wheelbarrow-style design enhances both mobility and stability, enabling seamless navigation and consistent performance, even on rugged terrain. With its strong steel tubing frame, the assembly is built to last, providing stability and safeguarding internal components, even in challenging environments. The reversible handle offers further versatility, as its different positions make the unit less bulky when stored.
With its hefty 142 lbs, this unit isn't exactly easy to handle, making manual lifting and transport quite a daunting task, especially on uneven terrain. The main contributors to its 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
The Westinghouse WPX4400 comes with a spray gun, a wand, a pressure hose, 5 nozzles and a detergent injection feature, which are detailed below.
- Soap injection: Detergent is fed in through a siphon hose, since the device lacks a soap tank. The detergent is diluted with a 12:1 ratio by the Westinghouse WPX4400's automatic soap dilution mechanism. Once a soap nozzle is connected, the pressure washer automatically blends the detergent with the water flow.
- Pressure hose: The included 50 ft ⌀5/16" high-pressure hose can be neatly stored on the unit when not in use, utilizing a set of convenient hooks for convenient organization.
- Spray gun and wand: A side hook allows for an easy storage of the included ergonomic EnduraGrasp spray gun and its steel wand.
- Nozzles: Find details on the 5 included nozzles and their recommended surface applications in the table below.
