Zoom on the Champion 100781
In summary, the Champion 100781 is a heavy duty pressure washer, that offers an all-around versatile cleaning experience, and also:
- spot cleaning of hard, paint-free surfaces and out-of-reach areas
- intense cleaning of tough, paintless surfaces
- cleaning of painted and frail surfaces
- application of detergent and cleaning solutions
Using a 160 cc engine, its axial cam pump delivers a pressure of up to 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). Together, the values result in a 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.
Gasoline storage is facilitated by a steel fuel tank with a maximum capacity of 0.48 gallon.
Design & Handling

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. Since the 100781 has a set of two 12" solid wheels, it is still easily maneuvered and manipulated.

- The Champion 100781 and its 3000 PSI, ranks amongst gas-powered pressure washers with a comparably low pressure output, considering the units that cost between $400 and $500. If your priority is the highest possible power of the water stream, in this price range, we suggest checking out the DeWalt DXPW3625, which reaches up to 3600 PSI.
- This washer, with a GPM of 2.3 (gallons per minute) has a somewhat lower water flow value compared to devices in its price range. In case you are looking for a device which can most efficiently rinse away debris in the current price range, the Lifan LFQ3370E has the highest 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 you consider the highest overall cleaning power as a really important factor, the Lifan LFQ3370E and its 9900 Cleaning Units has one of the highest cleaning efficiency of all the similarly priced units.
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 average side of the price range.
