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
Its axial cam pump, which utilizes a powerful 224cc engine, may deliver a pressure of up to 3100 PSI (almost 52 times more than a standard garden hose) and a flow of up to 2.2 GPM. Corresponding to these values is a cleaning power of 6820 Cleaning Units.
To initiate the Champion engine of this gas-powered pressure washer, a traditional pull-start mechanism is employed.
The pressure washer's tank has a maximum capacity of 0.9 gallon for storing gasoline.
Design & Handling
With its wheelbarrow design, the Champion 100780 delivers superior maneuverability and stability, facilitating easy transport and steady performance across various surfaces. The sturdy steel frame ensures the longevity of the assembly, offering stability and protection for internal components, even during rigorous use. The reversible handle offers further versatility, as its different positions make the unit less bulky when stored.
At 67.2 lbs, this unit is light enough for easy handling, yet substantial enough to provide stability during operation. This substantial weight can be partially attributed to the incorporation of the 224cc Champion engine and a resilient steel frame. Yet, its two 12" solid wheels ensure the 100780 remains effortlessly maneuverable.
Main Features
The Champion 100780 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 100780 features an automatic soap dilution mechanism that dilutes detergent according to a predefined ratio of 12:1. Attachment of a soap nozzle prompts the pressure washer to automatically introduce and blend the detergent with the water.
- Pressure hose: The unit comes equipped with an included 25 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: A side hook allows for an easy storage of the included classic ergonomic spray gun and its wand.
- Nozzles: Review the table below to learn about the 5 included nozzles and the surfaces they're recommended for.
