Zoom on the Champion 100784

The Champion 100784, a heavy duty, commercial pressure washer, gives its user an all-around versatile cleaning experience, topped off by the following features:

  • spot cleaning of hard, paint-free surfaces and out-of-reach areas
  • thorough cleaning of hard, paint-free surfaces
  • cleaning of painted and frail surfaces
  • application of detergent and cleaning solutions

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

Power

The Champion 100784 in use

The Champion 100784

Using a powerful 224 cc engine, its axial cam pump delivers a pressure of up to 3200 PSI (roughly 53 times more than a standard garden hose) and a flow of up to 2.5 GPM (values claimed by the manufacturer). Together, the values result in a cleaning power of 8000 Cleaning Units.

The Champion engine of this gas-powered pressure washer relies on an old-school pull-start mechanism to get started.

The fuel is stored in a tank, which can hold up to 0.9 gallon of gasoline.

Design & Handling

The wheelbarrow design of the Champion 100784 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.

Most users can maneuver this model easily, as it weighs just 68.8 lbs. One of the largest contributors to its weight are its 224 cc Champion engine and its steel frame. The 100784 can still be easily manipulated and maneuvered, thanks to its two 12" solid wheels.

Main Features

Along with the Champion 100784 itself, the package also includes a spray gun, a wand, a pressure hose, 5 nozzles and a detergent injection feature, which are discussed in further detail below.

  • Soap injection: A safe detergent storage is facilitated by a 1 gal tank. The automatic soap dilution mechanism of the Champion 100784 will dilute the 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 enables you to easily store 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.
