Zoom on the Simpson MS60921-S

In a nutshell, the Simpson MS60921-S is a heavy duty, commercial pressure washer, which not only offers an all-around versatile cleaning experience, but that also allows:

  • spot cleaning of hard, paint-free surfaces and out-of-reach areas
  • intense cleaning of tough, paintless surfaces
  • cleaning of painted or delicate surfaces
  • applying detergent and cleaning solutions

Ahead are presented its power characteristics and design, its main features and any other additional features.

Power

The Simpson MS60921-S in use

The Simpson MS60921-S

Using a 187 cc (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 (values claimed by the manufacturer). 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.

A fuel tank with a maximum capacity of 0.48 gallon is used to store gasoline.

Design & Handling

The wheelbarrow design of the Simpson MS60921-S grants mobility and stability to the unit. The robust and sturdy welded steel frame offers longevity to the assembly. The handle adds to the MS60921-S convenience of transport.

The majority of users will be able to maneuver this unit easily, it only weighs 71 lbs. Its 187 cc Honda GC190 engine and welded steel frame all add up to a substantial part of that weight. However, the two 10" pneumatic wheels allow the MS60921-S to be easily manipulated and maneuvered.

Main Features

The Simpson MS60921-S in use

The Simpson MS60921-S

Along with the Simpson MS60921-S itself, the package also includes a spray gun, a wand, a pressure hose, 5 nozzles and a detergent injection feature, which are discussed in further detail below.

  • Soap injection: While the device doesn't feature a soap tank, detergent supply is ensured by a siphon hose. The Simpson MS60921-S features an automatic soap dilution mechanism, that will dilute your 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 25 ft ⌀1/4" high-pressure hose, which is included with the device, can be stored neatly on the unit itself when idle, using a set of convenient hooks.
  • Spray gun and wand: The included classic ergonomic spray gun and its steel wand can be easily stored in a side hook.
  • Nozzles: The table below shows you the 5 included nozzles, as well as the surfaces they're the most appropriate for.
