Power

The Champion 100781 in use

The Champion 100781

Powered by a 160 cc engine, its axial cam pump can deliver a pressure of 3000 PSI (around 50 times more than a standard garden hose) and a flow of up to 2.3 GPM (values claimed by the manufacturer). Combined, these values mean that the Champion 100781 has a cleaning power of 6900 Cleaning Units.

A classic pull-start mechanism is responsible for starting the gas-powered pressure washer’s Honda GC160 engine.

Gasoline storage is facilitated by a steel fuel tank with a maximum capacity of 0.48 gallon.

Design & Handling

The wheelbarrow design of the Champion 100781 grants mobility and stability to the unit. The robust steel frame guarantees longevity of the assembly. The adds to the 100781 convenience of transport.

The device can be maneuvered with ease by most, since it only weighs 62 lbs. Its 160 cc Honda GC160 engine and steel frame all add up to a substantial part of that weight. The 100781 can still be easily manipulated and maneuvered, thanks to its two 12" solid wheels.

Main Features

The Champion 100781 comes with a spray gun, a wand, a pressure hose, 5 nozzles and a detergent injection feature, which are detailed below.

  • Soap injection: A safe detergent storage is facilitated by a 1 gal tank. The automatic soap dilution mechanism of the Champion 100781 will dilute the detergent with a 12:1 ratio. The detergent is automatically added to the water when a soap nozzle is connected.
  • Pressure hose: The included 25 ft ⌀5/8" high-pressure hose can be neatly stored on the unit when idle thanks to a set of easy-to-use straps.
  • Spray gun and wand: The included classic ergonomic spray gun and its wand can be easily stored in a side hook.
