The following sections will present you in detail its power characteristics and design, its main features and all the additional features it has to offer.

Power

The Champion 100786 in use

The Champion 100786

Fueled by a powerful 224cc engine, its brass triplex pump can generate a forceful pressure of 3500 PSI (roughly 58 times that of a standard garden hose) and a flow rate of up to 2.5 GPM (values claimed by the manufacturer). When these values are taken together, they yield a cleaning power of 8750 Cleaning Units.

The Champion engine of this gas pressure washer is activated by pulling a starter cord, following a traditional approach.

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

Design & Handling

Featuring a wheelbarrow design, the Champion 100786 prioritizes maneuverability and stability, ensuring smooth handling and reliable functionality in demanding cleaning applications. The durable steel frame of the assembly ensures its longevity, providing stability and shielding internal components from damage, even in tough conditions. The reversible handle offers further versatility, as its different positions make the unit less bulky when stored.

Weighing in at 87 lbs, it's safe to say this unit isn't lightweight, which might pose difficulties for users when it comes to lifting and transporting, particularly over uneven surfaces. The main contributors to its weight are its 224cc Champion engine, the triplex pump and steel frame. Despite this, the presence of two 10" solid wheels reduces the complexity of moving the 100786, even on rugged surfaces.

Main Features

The Champion 100786 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 100786 includes an automatic soap dilution mechanism, which will dilute the detergent using a 12:1 ratio. The pressure washer automatically dispenses and mixes the detergent with the water when a soap nozzle is attached.
  • Pressure hose: The unit comes equipped with an included 50 ft ⌀5/8" high-pressure hose, which can be neatly stored on the unit when idle, thanks to a set of easy-to-use straps, ensuring easy access and organization.
  • Spray gun and wand: The included classic ergonomic spray gun and its wand can be easily stored in a side hook.
  • Nozzles: In the table below, you can see the 5 included nozzles alongside their respective recommended surface uses.
