Zoom on the Simpson MS60920-S

The Simpson MS60920-S is a heavy duty, commercial pressure washer, and enables:

  • spot cleaning of hard, unpainted surfaces or high reach areas
  • thorough cleaning of hard, paint-free surfaces
  • cleaning of painted and frail surfaces
  • application of detergent and cleaning solutions

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

Power

Using a 187 cc (6 hp) engine, its axial cam pump delivers a pressure of up to 3200 PSI (roughly 53 times more than a standard garden hose) and a flow of up to 2.5 GPM (values claimed by the manufacturer). Together, the values result in a cleaning power of 8000 Cleaning Units.

This gas-powered pressure washer’s Honda GC190 engine is started by a traditional pull-start mechanism.

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

Design & Handling

The Simpson MS60920-S offers superb mobility, with a hand truck design and approximate dimensions of D23.2 x W21 x H34.8 in. The strong welded steel frame assures assembly longevity. The folding handle enhances its mobility, while allowing for a convenient storage.

Most users can maneuver this model easily, as it weighs just 65 lbs. One of the largest contributors to its weight are its 187 cc Honda GC190 engine and its welded steel frame. The MS60920-S can still be easily manipulated and maneuvered, thanks to its two never-flat wheels.

Main Features

The Simpson MS60920-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 is stored in a dedicated tank. The automatic soap dilution mechanism of the Simpson MS60920-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 50 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 easy-to-use straps.
  • Spray gun and wand: Both the classic ergonomic spray gun and its steel wand may be conveniently stored in a side hook.
  • Nozzles: The table below shows you the 4 included nozzles, as well as the surfaces they're the most appropriate for.
