Zoom on the Simpson MS60805-S
In summary, the Simpson MS60805-S is a heavy duty pressure washer, which provides:
- spot cleaning of hard, paintless surfaces and reaching far-away areas
- intense cleaning of tough, paintless surfaces
- cleaning of painted and fragile surfaces
- applying detergent and cleaning solutions
Powered by a 160 cc (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 (values claimed by the manufacturer). Combined, these values mean that the Simpson MS60805-S has a cleaning power of 7200 Cleaning Units.
A classic pull-start mechanism is responsible for starting the gas-powered pressure washer’s Honda GCV160 engine.
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 steel frame guarantees longevity of the assembly. The handle adds to the MS60805-S convenience of transport.
Weighing 56 lbs, the unit is easy to maneuver by most people. A major component of its weight are its 160 cc Honda GCV160 engine and steel frame. But, as the MS60805-S does have a set of two 12" never-flat wheels, it can be easily maneuvered and manipulated.
The Simpson MS60805-S's package includes a spray gun, a wand, a pressure hose, 4 nozzles and a detergent injection feature, with a more detailed description below.
- Soap injection: Detergent storage is ensured by a dedicated tank. The automatic soap dilution mechanism of the Simpson MS60805-S will dilute the detergent with a 7:1 ratio. If a soap nozzle is attached, the device will proceed to add the detergent to the water automatically.
- Pressure hose: The included 25 ft ⌀1/4" high-pressure hose can be neatly stored on the unit when idle thanks to a set of convenient hooks.
- Spray gun and wand: A side hook enables you to easily store the included classic ergonomic spray gun and its steel wand.
