Zoom on the Briggs & Stratton 20505

In a nutshell, the Briggs & Stratton 20505 is a heavy duty, commercial pressure washer that allows:

  • spot cleaning of hard, unpainted surfaces or high reach areas
  • thorough cleaning of hard, paint-free surfaces
  • cleaning of painted and fragile surfaces
  • use of detergent and cleaning solutions

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

Power

The Briggs & Stratton 20505 in use

The Briggs & Stratton 20505

Using an impressive 250 cc engine, its axial cam pump delivers a pressure of up to 3400 PSI (roughly 57 times more than a standard garden hose) and a flow of up to 2.8 GPM (values claimed by the manufacturer). Together, the values result in 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 robust steel tubing frame guarantees longevity of the assembly. The handle adds to the 20505 convenience of transport.

The device can be maneuvered with ease by most, since it only weighs 68 lbs. Its 250 cc Briggs & Stratton 1150 Series™ engine and steel tubing frame all add up to a substantial part of that weight. The 20505 can still be easily manipulated and maneuvered, thanks to its two 10" never-flat wheels.

Main Features

The Briggs & Stratton 20505 in use

The Briggs & Stratton 20505

The Briggs & Stratton 20505 comes with a spray gun, a wand, a pressure hose, 4 nozzles and a detergent injection feature, which are detailed below.

  • Soap injection: Detergent is fed in through a siphon hose, since the device lacks a soap tank. When a soap nozzle is connected, the detergent will be added automatically to the water.
  • Pressure hose: The included 30 ft ⌀1/4" high-pressure hose can be neatly stored on the unit when idle thanks to a set of convenient hooks.
  • Spray gun and wand: Both the classic ergonomic spray gun and its wand may be conveniently stored in a side hook.
  • Nozzles: The 4 nozzles included with the device, and the respective surfaces which they’re the most suitable for, are shown in the following table.

Other Features

  • Accessories: Besides the usual owner's manual (opens in a new tab) and documentation to get you promptly started, the Briggs & Stratton 20505 comes with soap hose, oil, wand, spray gun and pressure hose.
  • Emissions: The Briggs & Stratton 20505 is EPA-approved and CARB-compliant. Thus, selling and purchasing this pressure washer is allowed in each of the 50 states, including California.

This unit is now discontinued, but used to be sold around $580.

  • Able to deliver a maximum pressure of 3400 PSI, the Briggs & Stratton 20505 is one of the gas-powered products that produce an above average water pressure, in the $475 to $625 price range.
