The Simpson MS60921-S in use

Using a 187cc (6 hp) engine, its axial cam pump delivers a pressure of up to 3300 PSI (roughly 55 times more than a standard garden hose) and a flow of up to 2.4 GPM (CETA-certified values). Together, the values result in a cleaning power of 7920 Cleaning Units.

A classic pull-start mechanism is responsible for starting the gas-powered pressure washer’s Honda GC190 engine.

Gasoline storage is facilitated by a fuel tank with a maximum capacity of 0.48 gallon.

Design & Handling
