- spot cleaning of hard, unpainted surfaces or high reach areas
- intense cleaning of hard, unpainted surfaces

The Simpson engine of this gas-powered pressure washer relies on an old-school pull-start mechanism to get started.
Gasoline storage is facilitated by a fuel tank with a maximum capacity of 0.7 gallon.
