Zoom on the Westinghouse WPX4400
In summary, the Westinghouse WPX4400 is a heavy duty, commercial pressure washer, that offers an all-around versatile cleaning experience, and also:
- spot cleaning of hard, paintless surfaces and reaching far-away areas
- thorough cleaning of hard, paint-free surfaces
- cleaning of painted and frail surfaces
- use of detergent and cleaning solutions
The Westinghouse WPX4400's brass triplex pump, powered by an impressive 420cc engine, can provide a pressure of up to 4400 PSI (approximately 73 times more than a standard garden hose) and a flow of up to 4.2 GPM (values claimed by the manufacturer). The Westinghouse WPX4400 thus has a cleaning power of 18480 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 1.72 gallon.
Design & Handling
The wheelbarrow design of the Westinghouse WPX4400 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.
With a weight of 142 lbs, the model is not lightweight. Therefore, it may be challenging to manually carry it around and transport it. A key role in its final weight is played by its 420cc engine, the triplex pump and steel tubing frame. However, the unit is mobile thanks to its two 12" wheels, which add to its movability and allow it to be manipulated smoothly on the job.
The Westinghouse WPX4400'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: Even though the device doesn't have a soap tank, detergent is supplied by a siphon hose. The detergent is diluted with a 12:1 ratio by the Westinghouse WPX4400's automatic soap dilution mechanism. When a soap nozzle is connected, the detergent will be added automatically to the water.
- Pressure hose: A neat storage for the included 50 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 ergonomic EnduraGrasp 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.
