Thus, the Champion 100778 achieves 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
Characterized by its wheelbarrow layout, the Champion 100778 provides improved mobility and stability, facilitating easy movement and steadfast operation for effective cleaning results. The robust steel frame guarantees longevity of the assembly, providing stability and protection for internal components, even under demanding working conditions. The reversible handle offers further versatility, as its different positions make the unit less bulky when stored.
Weighing 67.2 lbs, this unit offers a manageable weight that allows for easy handling by most individuals. This weight is largely influenced by the presence of the 196cc Champion engine and a robust steel frame. Yet, its two 12" solid wheels ensure the 100778 remains effortlessly maneuverable.
Main Features
Along with the Champion 100778 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: Detergent storage is facilitated by the inclusion of a 1 gal tank. The Champion 100778 has an automatic soap dilution mechanism, which dilutes the detergent using a 12:1 ratio. When a soap nozzle is connected, the pressure washer takes the initiative to mix the detergent with the water flow automatically.
- Pressure hose: For easy organization, the included 25 ft ⌀5/8" high-pressure hose can be stored on the unit using a set of easy-to-use straps when it's not in use, ensuring a clutter-free workspace.
- Spray gun and wand: The included classic ergonomic spray gun and its wand can be easily stored in a side hook.
- Nozzles: The following table provides information on the 5 included nozzles and their recommended surface uses.
