Description
Zoom on the Simpson MS61084-S
The Simpson MS61084-S, a heavy duty, commercial pressure washer, gives its user an all-around versatile cleaning experience, topped off by the following features:
- spot cleaning of hard, paint-free surfaces and out-of-reach areas
- intense cleaning of hard, unpainted surfaces
- cleaning of painted and fragile surfaces
- use 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
With a 196cc (6.5 hp) engine, its axial cam pump delivers a pressure of 3400 PSI (roughly 57 times more than a standard garden hose) and a flow of up to 2.5 GPM (CETA-certified values), resulting in the Simpson MS61084-S's cleaning power of 8500 Cleaning Units.
A classic pull-start mechanism is responsible for starting the gas-powered pressure washer’s Kohler SH265 engine.
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. Its 196cc Kohler SH265 engine and welded steel frame account for a good chunk of that weight. Since the MS61084-S has a set of two 10" pneumatic wheels, it is still easily maneuvered and manipulated.
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: While the device doesn't feature a soap tank, detergent supply is ensured by a siphon hose. When a soap nozzle is connected, the detergent will be added automatically to the water.
- Pressure hose: Using a set of convenient hooks, the included 25 ft ⌀5/16" high-pressure hose can be easily stored on the unit when it is not running.
- Spray gun and wand: The included classic ergonomic spray gun and its wand can be easily stored in a side hook.
- Nozzles: The following table illustrates the 5 included nozzles, along with the surfaces which they are the most suitable for.
