Description
Zoom on the Simpson MS61114
In a nutshell, the Simpson MS61114 is a heavy duty pressure washer that allows:
- spot cleaning of hard, unpainted surfaces, reaching high areas, and removing stubborn stains
- comprehensive cleaning of hard surfaces, vehicle washing, and readying surfaces for painting
- mild cleaning for delicate surfaces, and low-pressure cleaning for broader areas
- applying detergent and cleaning solutions, and rinsing surfaces
Ahead are presented its power characteristics and design, its main features and any other additional features.
Power
Powered by a 149cc engine, its axial cam pump can deliver a pressure of 2800 PSI (around 47 times more than a standard garden hose) and a flow of up to 2.3 GPM (CETA-certified values). With these values combined, the Simpson MS61114 boasts a cleaning power of 6440 Cleaning Units.
Starting the KOHLER XTX675 engine of this gas pressure washer involves using a conventional pull-start method.
Containing gasoline, the pressure washer's steel fuel tank can hold a maximum of 0.3 gallon.
Design & Handling
The Simpson MS61114's mobility is greatly enhanced by its hand truck design. The welded steel frame's robustness ensures the assembly's longevity, maintaining stability and protecting internal components, even in the harshest environments. The handle adds to the MS61114 convenience of transport.
At 55 lbs, this unit strikes a balance between portability and stability, making it easy for most users to handle. The incorporation of the 149cc KOHLER XTX675 engine and a durable welded steel frame contribute considerably to its overall weight. Even so, the MS61114's two 12" never-flat wheels maintain easy maneuverability.
Main Features
The Simpson MS61114's package includes a spray gun, a wand, a pressure hose, 4 nozzles and a detergent injection feature, with a more detailed description below.
- Soap injection: Detergent is stored in a dedicated tank. Utilizing an automatic soap dilution mechanism, the Simpson MS61114 accurately mixes detergent to the defined ratio of 7:1, enhancing cleaning efficiency. Once a soap nozzle is connected, the pressure washer automatically blends the detergent with the water flow.
- Pressure hose: Utilizing a set of easy-to-use straps, the unit offers a convenient solution for storing the included 25 ft ⌀1/4" high-pressure hose when it's not in use, keeping it neatly organized.
- Spray gun and wand: A side hook allows for an easy storage of the included classic ergonomic spray gun and its wand.
- Nozzles: Review the table below to learn about the 4 included nozzles and the surfaces they're recommended for.
