Zoom on the Champion 100778

In summary, the Champion 100778 is a medium to heavy duty pressure washer, that offers an all-around versatile cleaning experience, and also:

  • spot cleaning of hard, unpainted surfaces and high-reach cleaning
  • intense cleaning of hard, unpainted surfaces
  • cleaning of painted and frail surfaces
  • applying detergent and cleaning solutions

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 100778 in use

The Champion 100778

Using a 196 cc engine, its axial cam pump delivers a pressure of up to 2800 PSI (roughly 47 times more than a standard garden hose) and a flow of up to 2.1 GPM (values claimed by the manufacturer). Together, the values result in a cleaning power of 5880 Cleaning Units.

The Champion engine of this gas-powered pressure washer gets started by a classic pull-start mechanism.

The fuel is stored in a tank, which can hold up to 0.9 gallon of gasoline.

Design & Handling

The wheelbarrow design of the Champion 100778 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.

Weighing 67.2 lbs, the unit is easy to maneuver by most people. Its 196 cc Champion engine and steel frame all add up to a substantial part of that weight. Nethertheless, thanks to its two 12" solid wheels, the 100778 remains very easy to manipulate and maneuver.

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 is stored in a 1 gal tank. The Champion 100778 includes an automatic soap dilution mechanism, which will dilute the detergent using a 12:1 ratio. The detergent will be added automatically to the water when a soap nozzle is attached.
  • Pressure hose: The included 25 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: A side hook allows for an easy storage of the included classic ergonomic spray gun and its wand.
  • Nozzles: The 5 included nozzles, and the respective surfaces they’re appropriate for, are listed in the table below.

Some of the included accessories

  • Onboard storage: The Champion 100778 features a handy storage area, which allows you to neatly store nozzles and accessories and be always prepared by having everything needed at hand.

  • Accessories: The Champion 100778 comes with an owner's manual (opens in a new tab) and some basic documentation to get you quickly started. On top of that, you also get soap hose, wand, oil, funnel, pressure hose and spray gun.
  • Emissions: The Champion 100778 is NOT CARB-compliant. Thus, it cannot be purchased or sold in California.

The Champion 100778's performance versus other pressure washers

The following charts are provided to give you an idea of how the key specs of the Champion 100778 compare to similarly priced pressure washers.

  • The Champion 100778, which can achieve a PSI of up to 2800, falls behind the other gas-powered pressure washers in the $300 to $400 price range. In case you are looking for a device with the highest possible power of its water stream, one of the top achievers in this price range is the Westinghouse WPX3400 with a PSI of 3400.
  • In the aforementioned price range, this washer, with 2.1 GPM (gallons per minute), is placed on the lower end of the GPM scale. If rinsing away debris most efficiently is your priority, one of the devices with the highest GPM in this price range is the Predator 3100, which can reach up to 2.8 GPM.
  • The 100778 has 5880 Cleaning Units (PSI x GPM), which can be considered low in comparison to other gas-powered devices of this price. If the highest overall cleaning power is your top priority, the Predator 3200, which can reach up to 8960 Cleaning Units, is one of the most efficient of the devices in the current price range.

Price comparison

As you can see from this interactive chart, when compared to other gas-powered washers between 5200 and 6300 Cleaning Units, the Champion 100778 is on the expensive side of the price range.

While certainly not the cheapest of its cleaning power range, purchasing it could most likely also mean enjoying the reliability of a high-end product.

WEAKNESSES:
