Zoom on the Champion 100778

In a nutshell, the Champion 100778 is a medium to heavy duty pressure washer, which not only offers an all-around versatile cleaning experience, but that also allows:

  • spot cleaning of hard, paintless surfaces and reaching far-away areas
  • intense cleaning of tough, paintless surfaces
  • cleaning of painted or delicate surfaces
  • applying detergent and cleaning solutions

Ahead are presented its power characteristics and design, its main features and any other additional features.

Power

The Champion 100778 in use

The Champion 100778

Its axial cam pump, which utilizes a 196cc engine, may deliver a pressure of up to 2800 PSI (almost 47 times more than a standard garden hose) and a flow of up to 2.1 GPM. These values correspond to a cleaning power of 5880 Cleaning Units.

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

A fuel tank with a maximum capacity of 0.9 gallon is used to store gasoline.

Design & Handling

The wheelbarrow design of the Champion 100778 grants mobility and stability to the unit. Its sturdy steel frame provides longevity to the assembly. The reversible handle offers further versatility, as its different positions make the unit less bulky when stored.

Weighing 67.2 lbs, the unit is easy to maneuver by most people. A major component of its weight are its 196cc Champion engine and steel frame. Nethertheless, thanks to its two 12" solid wheels, the 100778 remains very easy to manipulate and maneuver.

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: A safe detergent storage is facilitated by a 1 gal tank. The Champion 100778 features an automatic soap dilution mechanism, that will dilute your detergent with a 12:1 ratio. When a soap nozzle is connected, the detergent will be added automatically to the water.
  • Pressure hose: A neat storage for the included 25 ft ⌀5/8" high-pressure hose is facilitated by a set of easy-to-use straps.
  • Spray gun and wand: A side hook allows for an easy storage of the included classic ergonomic spray gun and its wand.
  • Nozzles: The 5 included nozzles, and the respective surfaces they’re appropriate for, are listed in the table below.
