The Briggs & Stratton 20505 in use

The Briggs & Stratton 20505

Its axial cam pump, which utilizes a powerful 250 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 2.8 GPM. These values correspond to a cleaning power of 9520 Cleaning Units.

This gas-powered pressure washer’s Briggs & Stratton 1150 Series™ engine is started by a traditional pull-start mechanism.

The fuel is stored in a tank, which can hold up to 0.75 gallon of gasoline.

Design & Handling

The wheelbarrow design of the Briggs & Stratton 20505 grants mobility and stability to the unit. The strong steel tubing frame assures assembly longevity. The handle adds to the 20505 convenience of transport.

The majority of users will be able to maneuver this unit easily, it only weighs 68 lbs. One of the largest contributors to its weight are its 250 cc Briggs & Stratton 1150 Series™ engine and its steel tubing frame. Nethertheless, thanks to its two 10" never-flat wheels, the 20505 remains very easy to manipulate and maneuver.

Beginning in the early 2000's, Briggs & Stratton began to acquire other companies such as Generac Portable Power Systems and Simplicity, thereby expanding into the ownership of manufacturing not just engines, but portable outdoor power equipment such as generators, pressure washers, and other home products.
