Power

The Champion 100781 in use

The Champion 100781

With a 160 cc engine, its axial cam pump delivers a pressure of 3000 PSI (roughly 50 times more than a standard garden hose) and a flow of up to 2.3 GPM (values claimed by the manufacturer), resulting in the Champion 100781's cleaning power of 6900 Cleaning Units.

The Honda GC160 engine of this gas-powered pressure washer relies on an old-school pull-start mechanism to get started.

The fuel is stored in a steel tank, which can hold up to 0.48 gallon of gasoline.

Design & Handling

The wheelbarrow design of the Champion 100781 grants mobility and stability to the unit. The robust steel frame guarantees longevity of the assembly. The adds to the 100781 convenience of transport.

With a weight of 62 lbs, the unit can be easily maneuvered by most users. Its 160 cc Honda GC160 engine and steel frame all add up to a substantial part of that weight. However, the two 12" solid wheels allow the 100781 to be easily manipulated and maneuvered.

Main Features

Along with the Champion 100781 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: A safe detergent storage is facilitated by a 1 gal tank. The Champion 100781 has an automatic soap dilution mechanism, which dilutes the detergent using a 12:1 ratio. The detergent is automatically added to the water when a soap nozzle is connected.
  • 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 enables you to easily store the included classic ergonomic spray gun and its wand.
  • Nozzles: The following table illustrates the 5 included nozzles, along with the surfaces which they are the most suitable for.

The Champion 100781's performance versus other pressure washers

The following charts are provided to give you an idea of how the key specs of the Champion 100781 compare to similarly priced pressure washers.

  • The Champion 100781 with its 3000 PSI achieves a lower pressure value, compared to other gas-powered pressure washers in the $400-500 price range. If your priority is the highest possible power of the water stream, in this price range, we suggest checking out the Champion 100786, which reaches up to 3500 PSI.
  • In comparison to other devices in the above-mentioned price range, this washer and its 2.3 GPM (gallons per minute), has one of the lower GPM values. If maximum rinsing efficiency is your top priority, one of the devices with the highest water flow in the same price range is the Lifan LFQ3370E, with a GPM of 3.
  • The 100781 ranks as below average in terms of Cleaning Units, compared to gas-powered devices in its price range, reaching only a value of 6900 CU (PSI x GPM). If the highest overall cleaning power is your top priority, the Lifan LFQ3370E, which can reach up to 9900 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 6500 and 7000 Cleaning Units, the Champion 100781 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.
