Power

The Simpson MS60805-S in use

The Simpson MS60805-S

Powered by a 160cc (4.4 hp) engine, its axial cam pump can deliver a pressure of 3000 PSI (around 50 times more than a standard garden hose) and a flow of up to 2.4 GPM (CETA-certified values). With these values combined, the Simpson MS60805-S boasts a cleaning power of 7200 Cleaning Units.

To initiate the Honda GCV160 engine of this gas-powered pressure washer, a traditional pull-start mechanism is employed.

Containing gasoline, the pressure washer's fuel tank can hold a maximum of 0.25 gallon..

Design & Handling

The Simpson MS60805-S's mobility is greatly enhanced by its hand truck design. The robust welded steel frame guarantees longevity of the assembly, providing stability and protection for internal components, even under demanding working conditions. The handle adds to the MS60805-S convenience of transport.

At 56 lbs, this unit is light enough for easy handling, yet substantial enough to provide stability during operation. This substantial weight can be partially attributed to the incorporation of the 160cc Honda GCV160 engine and a resilient welded steel frame. Nevertheless, the MS60805-S's two 12" never-flat wheels ensure it remains easy to maneuver.

Main Features

The Simpson MS60805-S

The Simpson MS60805-S comes with a spray gun, a wand, a pressure hose, 4 nozzles and a detergent injection feature, which are detailed below.
