  • 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
  • gentle cleaning for sensitive surfaces, and wide coverage cleaning with low pressure
  • utilizing cleaning solutions, and rinsing surfaces clean

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

Power

Utilizing a 196cc (6.5 hp) engine, this machine's axial cam pump can deliver a pressure of 3400 PSI (around 57 times stronger than a standard garden hose) and a flow rate of up to 2.5 GPM (CETA-certified values). Thus, the Simpson MS61084-S achieves a cleaning power of 8500 Cleaning Units.

The Kohler SH265 engine of this gas pressure washer is activated by pulling a starter cord, following a traditional approach.

Containing gasoline, the pressure washer's steel fuel tank can hold a maximum of 3.4 gallons..

Design & Handling

The wheelbarrow design of the Simpson MS61084-S offers enhanced mobility and stability, making it ideal for navigating uneven terrain and ensuring steady operation during heavy-duty cleaning tasks. Guaranteeing longevity, the robust welded steel frame offers stability and protects internal components, even when subjected to demanding tasks. The reversible handle offers further versatility, as its different positions make the unit less bulky when stored.

With a weight of 64 lbs, the unit is comfortably maneuverable for most users, allowing for efficient handling during cleaning tasks. 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

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: Even though the device doesn't have a soap tank, detergent is supplied by a siphon hose. 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 provides a convenient way to store the included 25 ft ⌀5/16" high-pressure hose when not in use, keeping it organized and readily accessible.
  • Spray gun and wand: Both the classic ergonomic spray gun and its wand may be conveniently stored in a side hook.
  • Nozzles: Find details on the 5 included nozzles and their recommended surface applications in the table below.
