  • spot cleaning of hard, paint-free surfaces and out-of-reach areas

The following sections will present you in detail its power characteristics and design, its main features and all the additional features it has to offer.

Power

The Simpson MS60805-S in use

The Simpson MS60805-S

With a 160 cc (4.4 hp) 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 2.4 GPM (values claimed by the manufacturer), resulting in the Simpson MS60805-S's cleaning power of 7200 Cleaning Units.

The Honda GCV160 engine of this gas-powered pressure washer gets started by a classic pull-start mechanism.

Gasoline is stored in a fuel tank with a maximum capacity of 0.25 gallon.

Design & Handling

The Simpson MS60805-S is very mobile, due to its hand truck design and approximate dimensions of D26 x W18 x H35 in. The robust and sturdy steel frame offers longevity to the assembly. The handle adds to the MS60805-S convenience of transport.

The majority of users will be able to maneuver this unit easily, it only weighs 56 lbs. One of the largest contributors to its weight are its 160 cc Honda GCV160 engine and its steel frame. Nethertheless, thanks to its two 12" never-flat wheels, the MS60805-S remains very easy to manipulate and maneuver.
