The Westinghouse WPX3600 in use

The Westinghouse WPX3600

Using a powerful 212cc engine, its brass triplex pump delivers a pressure of up to 3600 PSI (roughly 60 times more than a standard garden hose) and a flow of up to 2.7 GPM (values claimed by the manufacturer). When these values are taken together, they yield a cleaning power of 9720 Cleaning Units.

Initiating the engine of this gas pressure washer is achieved through a classic pull-start process.

Containing gasoline, the pressure washer's fuel tank can hold a maximum of 0.95 gallon..

Design & Handling

With its wheelbarrow design, the Westinghouse WPX3600 delivers superior maneuverability and stability, facilitating easy transport and steady performance across various surfaces. The sturdy steel tubing frame ensures the longevity of the assembly, offering stability and protection for internal components, even during rigorous use. The reversible handle offers further versatility, as its different positions make the unit less bulky when stored.

Tipping the scales at 79 lbs, this unit's weight presents a notable challenge for users, especially when it comes to lifting and moving it, particularly over uneven ground. Its 212cc engine, the triplex pump and steel tubing frame add up to a large chunk of the device's weight. Despite this, the presence of two 10" wheels reduces the complexity of moving the WPX3600, even on rugged surfaces.

The Westinghouse WPX3600

The Westinghouse WPX3600 comes with a spray gun, a wand, a pressure hose, 5 nozzles and a detergent injection feature, which are detailed below.

  • Soap injection: A 0.8 gal tank ensures storage for detergent within the pressure washer. The automatic soap dilution mechanism of the Westinghouse WPX3600 will dilute the detergent with a 12:1 ratio. Upon connecting a soap nozzle, the pressure washer takes over the task of seamlessly combining the detergent with 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: A side hook allows for an easy storage of the included classic ergonomic spray gun and its steel wand.
  • Nozzles: Refer to the table below for details on the 5 included nozzles and their recommended surface applications.
