This is a perfect option for homeowners, because it’s lightweight and easy to maneuver.

Zoom on the Simpson MS60850-S

In a nutshell, the Simpson MS60850-S is a heavy duty 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
  • use of detergent and cleaning solutions

Its power characteristics and design, its main features and all its additional features are presented ahead.

Power

Powered by an impressive 208 cc (6 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). Combined, these values mean that the Simpson MS60850-S has a cleaning power of 7200 Cleaning Units.

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

Design & Handling

The wheelbarrow design of the Simpson MS60850-S grants mobility and stability to the unit. The strong welded steel frame assures assembly longevity. The handle adds to the MS60850-S convenience of transport.

Most users can maneuver this model easily, as it weighs just 69 lbs. Its 208 cc Simpson engine and welded steel frame account for a good chunk of that weight. But, as the MS60850-S does have a set of two 12" never-flat wheels, it can be easily maneuvered and manipulated.

Main Features

Along with the Simpson MS60850-S itself, the package also includes a spray gun, a wand, a pressure hose, a 5-in-1 nozzle and a detergent injection feature, which are discussed in further detail below.

  • Soap injection: Detergent is fed in through a siphon hose, since the device lacks a soap tank. The Simpson MS60850-S features an automatic soap dilution mechanism, that will dilute your detergent with a 7:1 ratio. Detergent is automatically added to the water when "soap" is selected on the 5-in-1 nozzle.
  • 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: Both the classic ergonomic spray gun and its steel wand may be conveniently stored in a side hook.
  • Nozzle: a 5-in-1 nozzle is included.

    Simpson's 5-in-1 nozzle Simpson's 5-in-1 nozzle offers five spray pattern settings (0°, 15°, 25°, 40°, soap). Selection of a specific spray pattern is made by simply rotating the spray selector to the desired setting.
