The Champion 100778 in use

The Champion 100778

With a 196cc engine powering it, the axial cam pump of this unit are capable of achieving a pressure of 2800 PSI (approximately 47 times greater than that of a standard garden hose) and a flow rate of up to 2.1 GPM (values claimed by the manufacturer). Corresponding to these values is a cleaning power of 5880 Cleaning Units.

Starting the Champion engine of this gas pressure washer involves using a conventional pull-start method.

Gasoline is stored in a fuel tank with a maximum capacity of 0.9 gallon.

Design & Handling

Designed with a wheelbarrow configuration, the Champion 100778 ensures improved mobility and stability, allowing for effortless movement and reliable operation on challenging surfaces. Guaranteeing longevity, the robust steel frame offers stability and protects internal components, even when subjected to demanding tasks. The reversible handle offers further versatility, as its different positions make the unit less bulky when stored.

With a weight of 67.2 lbs, the unit is comfortably maneuverable for most users, allowing for efficient handling during cleaning tasks. That weight is mainly due to the inclusion of the 196cc Champion engine and a solid steel frame. Still, the 100778's two 12" solid wheels ensure easy handling and maneuverability.

Main Features

The Champion 100778 comes with a spray gun, a wand, a pressure hose, 5 nozzles and a detergent injection feature, which are detailed below.

  • Soap injection: Detergent storage is ensured by a 1 gal tank. Featuring an automatic soap dilution mechanism, the Champion 100778 ensures detergent is mixed to the specified ratio of 12:1 for optimal cleaning results. When a soap nozzle is connected, the pressure washer takes the initiative to mix the detergent with the water flow automatically.
