Its power characteristics and design, its main features and all its additional features are presented ahead.

Power

The Westinghouse WPX3400 in use

The Westinghouse WPX3400

The Westinghouse WPX3400's axial cam pump, powered by a powerful 212 cc engine, can provide a pressure of up to 3400 PSI (approximately 57 times more than a standard garden hose) and a flow of up to 2.6 GPM (values claimed by the manufacturer). The Westinghouse WPX3400 thus has a cleaning power of 8840 Cleaning Units.

The engine of this gas-powered pressure washer relies on an old-school pull-start mechanism to get started.

Gasoline is stored in a fuel tank with a maximum capacity of 0.9 gallon.

Design & Handling

Thanks to its hand truck design and approximate dimensions of D21 x W19.5 x H39 in, the Westinghouse WPX3400 offers great mobility. The robust steel tubing frame guarantees longevity of the assembly. The foam-padded fixed handle adds to the WPX3400 convenience of transport, while offering a comfortable grip.

With a weight of 63 lbs, the unit can be easily maneuvered by most users. Its 212 cc engine and steel tubing frame account for a good chunk of that weight. Since the WPX3400 has a set of two 12" never-flat wheels, it is still easily maneuvered and manipulated.

Main Features

The Westinghouse WPX3400 in use

The Westinghouse WPX3400

The Westinghouse WPX3400 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 stored in a 0.5 gal tank. The Westinghouse WPX3400 has an automatic soap dilution mechanism, which dilutes the detergent using a 12:1 ratio. When a soap nozzle is connected, the detergent will be added automatically to the water.
  • Pressure hose: Using a set of convenient hooks, the included 25 ft ⌀5/16" high-pressure hose can be easily stored on the unit when it is not running.
  • Spray gun and wand: The included classic ergonomic spray gun and its steel wand can be easily stored in a side hook.
  • Nozzles: The table below shows you the 5 included nozzles, as well as the surfaces they're the most appropriate for.

The Westinghouse WPX3400's performance versus other pressure washers

The following charts are provided to give you an idea of how the key specs of the Westinghouse WPX3400 compare to similarly priced pressure washers.

  • The Westinghouse WPX3400, which can reach up to 3400 PSI, has one of the highest pressure outputs of the gas-powered units that cost between $300 and $400.
  • In the aforementioned price range, the 2.6 GPM (gallons per minute) of this washer makes it one of the better performing units in terms of the delivered volume of water. If maximum rinsing efficiency is your top priority, one of the devices with the highest water flow in the same price range is the Predator 3100, with a GPM of 2.8.
  • Reaching up to 8840 Cleaning Units (PSI x GPM), the WPX3400 is one of the more efficient amongst its similarly priced peers. In case you are looking for the highest overall cleaning power, in this price range, one of the current champions is the Predator 3200 and its 8960 Cleaning Units.
