  • spot cleaning of hard, unpainted surfaces or high reach areas

  • cleaning of painted and fragile surfaces

The following sections will present you in detail its power characteristics and design, its main features and all the additional features it has to offer.

Power

The Briggs & Stratton 20505 in use

The Briggs & Stratton 20505

Powered by an impressive 250 cc engine, its axial cam pump can deliver a pressure of 3400 PSI (around 57 times more than a standard garden hose) and a flow of up to 2.8 GPM (values claimed by the manufacturer). Combined, these values mean that the Briggs & Stratton 20505 has a cleaning power of 9520 Cleaning Units.

The Briggs & Stratton 1150 Series™ engine of this gas-powered pressure washer gets started by a classic pull-start mechanism.

Gasoline storage is facilitated by a fuel tank with a maximum capacity of 0.75 gallon.

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 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. But, as the 20505 does have a set of two 10" never-flat wheels, it can be easily maneuvered and manipulated.

Main Features

The Briggs & Stratton 20505's performance versus other pressure washers

The following charts are provided to give you an idea of how the key specs of the Briggs & Stratton 20505 compare to similarly priced pressure washers.

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

  • The Briggs & Stratton 20505, with a max water pressure of 3400 PSI, has one of the higher PSI values of the gas-powered products in the $500-600 price range. If you're going after the highest possible power of the water stream, one of the best in this price range is the DeWalt DXPW3625 that can reach up to 3600 PSI.
  • With a water flow of up to 2.8 GPM (gallons per minute), this washer belongs to the upper end of the above-mentioned price range, as it can deliver a high volume of water. If rinsing away debris most efficiently is your priority, one of the devices with the highest GPM in this price range is the Lifan LFQ3370E, which can reach up to 3 GPM.
  • Reaching up to 9520 Cleaning Units (PSI X GPM), the 20505 is one of the more efficient amongst its similarly priced peers. If you consider the highest overall cleaning power as a really important factor, the Lifan LFQ3370E and its 9900 Cleaning Units has one of the highest cleaning efficiency of all the similarly priced units.
