Power

The Westinghouse WPX3400 in use

The Westinghouse WPX3400

Its brass axial cam pump, which utilizes an impressive 212 cc engine, may deliver a pressure of up to 3400 PSI (almost 57 times more than a standard garden hose) and a flow of up to 2.6 GPM. These values correspond to 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. Its sturdy steel tubing frame provides longevity to the assembly. The foam-padded fixed handle adds to the WPX3400 convenience of transport, while offering a comfortable grip.

The majority of users will be able to maneuver this unit easily, it only weighs 63 lbs. One of the largest contributors to its weight are its 212 cc engine and its steel tubing frame. Nethertheless, thanks to its two 12" never-flat wheels, the WPX3400 remains very easy to manipulate and maneuver.
