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, unpainted surfaces or high reach areas
  • thorough cleaning of hard, paint-free 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

Its axial cam pump, which utilizes an impressive 208 cc (6 hp) engine, may deliver a pressure of up to 3000 PSI (almost 50 times more than a standard garden hose) and a flow of up to 2.4 GPM. These values correspond to a cleaning power of 7200 Cleaning Units.

The Simpson engine of this gas-powered pressure washer relies on an old-school pull-start mechanism to get started.

Design & Handling

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

Weighing 69 lbs, the unit is easy to maneuver by most people. Its 208 cc Simpson engine and welded steel frame account for a good chunk of that weight. Since the MS60850-S has a set of two 12" never-flat wheels, it is still 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 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.
  • 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.
