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, paint-free surfaces and out-of-reach areas
- intense cleaning of hard, unpainted surfaces
- cleaning of painted and fragile surfaces
- application of detergent and cleaning solutions
Ahead are presented its power characteristics and design, its main features and any other additional features.
Power
Using a 196 cc (6.5 hp) engine, its axial cam pump delivers a pressure of up to 3400 PSI (roughly 57 times more than a standard garden hose) and a flow of up to 2.5 GPM (CETA-certified values). Together, the values result in a cleaning power of 8500 Cleaning Units.
The Kohler SH265 engine of this gas-powered pressure washer gets started by a classic pull-start mechanism.
Gasoline is stored in a steel fuel tank with a maximum capacity of 3.4 gallons.
Design & Handling
The wheelbarrow design of the Simpson MS61084-S grants mobility and stability to the unit. The robust welded steel frame guarantees longevity of the assembly. 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 can be easily maneuvered by most users. 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
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 though the device doesn't have a soap tank, detergent is supplied by a siphon hose. Whenever a soap nozzle is connected, the detergent is automatically added to the water.
- Pressure hose: The 25 ft ⌀5/16" 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: Both the classic ergonomic spray gun and its wand may be conveniently stored in a side hook.
- Nozzles: The table below shows you the 5 included nozzles, as well as the surfaces they're the most appropriate for.
