Description

Zoom on the Simpson MS61084-S

The Simpson MS61084-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, paintless surfaces and reaching far-away areas
  • intense cleaning of hard, unpainted surfaces
  • cleaning of painted and frail 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 a 196 cc (6.5 hp) engine, its axial cam pump can deliver a pressure of 3400 PSI (around 57 times more than a standard garden hose) and a flow of up to 2.5 GPM (CETA-certified values). Combined, these values mean that the Simpson MS61084-S has a cleaning power of 8500 Cleaning Units.

The Kohler SH265 engine of this gas-powered pressure washer relies on an old-school pull-start mechanism to get started.

The fuel is stored in a steel tank, which can hold up to 3.4 gallons of gasoline.

Design & Handling

The wheelbarrow design of the Simpson MS61084-S grants mobility and stability to the unit. The strong welded steel frame assures assembly longevity. The reversible handle offers further versatility, as its different positions make the unit less bulky when stored.

Most users can maneuver this model easily, as it weighs just 64 lbs. One of the largest contributors to its weight are its 196 cc Kohler SH265 engine and its welded steel frame. Since the MS61084-S has a set of two 10" pneumatic wheels, it is still easily maneuvered and manipulated.

Main Features

Along with the Simpson MS61084-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 detergent will be added automatically to the water when a soap nozzle is attached.
  • Pressure hose: A neat storage for the included 25 ft ⌀5/16" high-pressure hose is facilitated by a set of convenient hooks.
  • Spray gun and wand: A side hook allows for an easy storage of the included classic ergonomic spray gun and its wand.
  • Nozzles: The table below shows you the 5 included nozzles, as well as the surfaces they're the most appropriate for.

If you’re after the highest rinsing efficiency, one of the units with the highest water flow in the current price range is the Predator 3100, that can deliver up to 2.8 GPM.
  • Reaching up to 8500 Cleaning Units (PSI x GPM), the MS61084-S is one of the more efficient amongst its similarly priced peers.
