Description
Zoom on the Champion 100790
In a nutshell, the Champion 100790 is a heavy duty, commercial pressure washer, which not only offers an all-around versatile cleaning experience, but that also allows:
- spot cleaning of hard, unpainted surfaces and high-reach cleaning
- intense cleaning of hard, unpainted surfaces
- cleaning of painted or delicate surfaces
- application of detergent and cleaning solutions
Ahead are presented its power characteristics and design, its main features and any other additional features.
Power
Powered by a powerful 389 cc engine, its brass triplex pump can deliver a pressure of 4200 PSI (around 70 times more than a standard garden hose) and a flow of up to 4 GPM (values claimed by the manufacturer). Combined, these values mean that the Champion 100790 has a cleaning power of 16800 Cleaning Units.
This gas-powered pressure washer’s Champion engine is started by a traditional pull-start mechanism.
Gasoline storage is facilitated by a steel fuel tank with a maximum capacity of 1.6 gallon.
Design & Handling
The wheelbarrow design of the Champion 100790 grants mobility and stability to the unit. The strong steel frame assures assembly longevity. The reversible handle offers further versatility, as its different positions make the unit less bulky when stored.
With a weight of 124.6 lbs, the model is not lightweight. Therefore, it may be challenging to manually carry it around and transport it. The main contributors to its weight are its 389 cc Champion engine, the triplex pump and steel frame. However, the unit is mobile thanks to its two 10" never-flat wheels, which add to its movability and allow it to be manipulated smoothly on the job.
Main Features
Along with the Champion 100790 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 is stored in a 1 gal tank. The automatic soap dilution mechanism of the Champion 100790 will dilute the detergent with a 12:1 ratio. The detergent will be added automatically to the water when a soap nozzle is attached.
- Pressure hose: The included 50 ft ⌀5/8" high-pressure hose can be neatly stored on the unit when idle thanks to 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.
0° | 15° | 25° | 40° | Soap | |

Other Features
- Onboard storage: The Champion 100790 features a handy storage area, which allows you to neatly store nozzles and accessories and be always prepared by having everything needed at hand.
- Safety: Safety of operation is enhanced by a trigger lock mechanism (which prevents accidental operation), a low oil protection and a thermal relief valve (which helps to prevent internal pump damage).
- Accessories: Included with the Champion 100790 are also the owner's manual (opens in a new tab) and some basic documentation to get you promptly started, along with several accessories, such as spray gun, funnel, soap hose, oil, pressure hose and wand.
- Emissions: The Champion 100790 is NOT CARB-compliant and so you cannot buy it nor sell it in California.
