Description

Zoom on the Simpson MS61084-S

In a nutshell, the Simpson MS61084-S is a heavy duty, commercial pressure washer, which not only offers an all-around versatile cleaning experience, but that also allows:

  • spot cleaning of hard, unpainted surfaces, reaching high areas, and removing stubborn stains
  • overall cleaning of hard surfaces, washing vehicles, and prepping surfaces for painting
  • mild cleaning for delicate surfaces, and low-pressure cleaning for broader areas
  • applying detergents and cleaning agents, and rinsing off surfaces

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

Power

Its axial cam pump, which utilizes a 196cc (6.5 hp) engine, may deliver a pressure of up to 3400 PSI (almost 57 times more than a standard garden hose) and a flow of up to 2.5 GPM. Corresponding to these values is a cleaning power of 8500 Cleaning Units.

To initiate the Kohler SH265 engine of this gas-powered pressure washer, a traditional pull-start mechanism is employed.

The pressure washer's steel tank has a maximum capacity of 3.4 gallons for storing gasoline.

Design & Handling

Featuring a wheelbarrow design, the Simpson MS61084-S prioritizes maneuverability and stability, ensuring smooth handling and reliable functionality in demanding cleaning applications. The welded steel frame's robustness ensures the assembly's longevity, maintaining stability and protecting internal components, even in the harshest environments. The reversible handle offers further versatility, as its different positions make the unit less bulky when stored.

This unit, weighing 64 lbs, strikes a comfortable balance between portability and stability, ensuring easy maneuvering for users of various strengths. This weight is largely influenced by the presence of the 196cc Kohler SH265 engine and a robust welded steel frame. Yet, its two 10" pneumatic wheels ensure the MS61084-S remains effortlessly maneuverable.

Main Features

The Simpson MS61084-S's package includes a spray gun, a wand, a pressure hose, 5 nozzles and a detergent injection feature, with a more detailed description below.

  • Soap injection: Even without a built-in soap tank, the device relies on a siphon hose to provide detergent. The pressure washer automatically dispenses and mixes the detergent with the water when a soap nozzle is attached.
  • Pressure hose: With a set of convenient hooks, the unit offers a practical solution for maintaining workspace order, allowing the included 25 ft ⌀5/16" high-pressure hose to be neatly stored when idle.
  • Spray gun and wand: A side hook enables you to easily store the included classic ergonomic spray gun and its wand.
  • Nozzles: In the table below, you can see the 5 included nozzles alongside their respective recommended surface uses.
