Zoom on the Simpson MS60921-S

The Simpson MS60921-S is a heavy duty, commercial pressure washer, that provides its users with an all-around versatile cleaning experience, and enables:

  • spot cleaning of hard, unpainted surfaces and high-reach cleaning
  • intense cleaning of tough, paintless surfaces
  • cleaning of painted and fragile surfaces
  • application of detergent and cleaning solutions

The following sections will present you in detail its power characteristics and design, its main features and all the additional features it has to offer.

Power

The Simpson MS60921-S in use

The Simpson MS60921-S

Its axial cam pump, which utilizes a 187 cc (6 hp) engine, may deliver a pressure of up to 3300 PSI (almost 55 times more than a standard garden hose) and a flow of up to 2.4 GPM. These values correspond to a cleaning power of 7920 Cleaning Units.

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

Gasoline is stored in a fuel tank with a maximum capacity of 0.48 gallon.

Design & Handling

The wheelbarrow design of the Simpson MS60921-S grants mobility and stability to the unit. The strong welded steel frame assures assembly longevity. 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 account for a good chunk of that weight. The MS60921-S can still be easily manipulated and maneuvered, thanks to its two 10" pneumatic wheels.

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: Detergent is fed in through a siphon hose, since the device lacks a soap tank. The Simpson MS60921-S includes an automatic soap dilution mechanism, which will dilute the detergent using 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 5 nozzles included with the device, and the respective surfaces which they’re the most suitable for, are shown in the following table.
