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
  • intense cleaning of tough, paintless surfaces
  • cleaning of painted and fragile surfaces
  • use 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 an impressive 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.

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

Gasoline storage is facilitated by a fuel tank with a maximum capacity of 0.9 gallon.

Design & Handling

The wheelbarrow design of the Champion 100784 grants mobility and stability to the unit. The robust steel frame guarantees longevity of the assembly. The reversible handle offers further versatility, as its different positions make the unit less bulky when stored.

With a weight of 68.8 lbs, the unit can be easily maneuvered by most users. Its 224 cc Champion engine and steel frame account for a good chunk of that weight. But, as the 100784 does have a set of two 12" solid wheels, it can be easily maneuvered and manipulated.

Main Features

The Champion 100784 comes with a spray gun, a wand, a pressure hose, 5 nozzles and a detergent injection feature, which are detailed below.

  • Soap injection: Detergent is stored in a 1 gal tank. The Champion 100784 includes an automatic soap dilution mechanism, which will dilute the detergent using a 12:1 ratio. The detergent is automatically added to the water when a soap nozzle is connected.
  • 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: The included classic ergonomic spray gun and its wand can be easily stored in a side hook.
  • Nozzles: The 5 nozzles included with the device, and the respective surfaces which they’re the most suitable for, are shown in the following table.
