Zoom on the Briggs & Stratton 20507
In summary, the Briggs & Stratton 20507 is a heavy duty, commercial pressure washer, that offers an all-around versatile cleaning experience, and also:
- focused spot cleaning on hard, unpainted surfaces, accessing high spots, and efficiently eliminating stubborn stains
- comprehensive cleaning of hard surfaces, vehicle washing, and readying surfaces for painting
- soft cleaning of delicate surfaces, and gentle cleaning for larger areas with low pressure
- applying detergent and cleaning solutions, and rinsing surfaces
Ahead are presented its power characteristics and design, its main features and any other additional features.
Power
Fueled by an impressive 420cc (13.5 hp) engine, its triplex pump can generate a forceful pressure of 4000 PSI (roughly 67 times that of a standard garden hose) and a flow rate of up to 4 GPM (values claimed by the manufacturer). When these values are taken together, they yield a cleaning power of 16000 Cleaning Units.
The Briggs & Stratton 2100 Series™ engine of this gas-powered pressure washer is initiated by a classic pull-start mechanism.
Containing gasoline, the pressure washer's fuel tank can hold a maximum of 1.75 gallon.
Design & Handling
Designed with a wheelbarrow configuration, the Briggs & Stratton 20507 ensures improved mobility and stability, allowing for effortless movement and reliable operation on challenging surfaces. The sturdy steel tubing frame ensures the longevity of the assembly, offering stability and protection for internal components, even during rigorous use. The handle adds to the 20507 convenience of transport.
Weighing in at 141 lbs, it's safe to say this unit isn't lightweight, which might pose difficulties for users when it comes to lifting and transporting, particularly over uneven surfaces. Its 420cc Briggs & Stratton 2100 Series™ engine, the triplex pump and steel tubing frame add up to a large chunk of the device's weight. However, the incorporation of two 12" never-flat wheels makes navigating the 20507 less cumbersome, even on uneven terrain.
Main Features
The Briggs & Stratton 20507 comes with a spray gun, a wand, a pressure hose, 5 nozzles and a detergent injection feature, which are detailed below.
- Soap injection: While not equipped with a soap tank, the device maintains detergent supply through a siphon hose. The pressure washer automatically dispenses and mixes the detergent with the water when a soap nozzle is attached.
- Pressure hose: With a set of convenient hooks, the unit offers a practical solution for maintaining workspace order, allowing the included 50 ft ⌀3/8" high-pressure hose to be neatly stored when idle.
- Spray gun and wand: A side hook enables you to easily store the included classic ergonomic spray gun and its wand.
- Nozzles: In the table below, you can see the 5 included nozzles alongside their respective recommended surface uses.
