Design & Handling
Thanks to its hand truck design and approximate dimensions of D26 x W18 x H35 in, the Simpson MS60773-S offers great mobility. Its sturdy steel frame provides longevity to the assembly. The handle adds to the MS60773-S convenience of transport.
Most users can maneuver this model easily, as it weighs just 61 lbs. Its 160 cc Honda GCV160 engine and steel frame all add up to a substantial part of that weight. However, the two 12" never-flat wheels allow the MS60773-S to be easily manipulated and maneuvered.
The Simpson MS60773-S comes with a spray gun, a wand, a pressure hose, 4 nozzles and a detergent injection feature, which are detailed below.
- Soap injection: Even though the device doesn't have a soap tank, detergent is supplied by a siphon hose. The Simpson MS60773-S features an automatic soap dilution mechanism, that will dilute your detergent with a 7:1 ratio. The detergent is automatically added to the water when a soap nozzle is connected.
- Pressure hose: The included 25 ft ⌀1/4" high-pressure hose can be neatly stored on the unit when idle thanks to a set of convenient hooks.
- Spray gun and wand: The included classic ergonomic spray gun and its steel wand can be easily stored in a side hook.
- Nozzles: The 4 nozzles included with the device, and the respective surfaces which they’re the most suitable for, are shown in the following table.

- Dial-N-Wash®: Simpson’s Dial-N-Wash® is an adjustable pressure regulator that allows you to choose a desired pressure for your specific cleaning application. High, medium and low pressure settings can be switched between easily by a simple twist. Its design assures its compatibility with most pressure washer standard spray wands and standard guns with threaded fittings.
- Onboard storage: The Simpson MS60773-S allows you to be always fully prepared, as it features a handy storage area, where nozzles and accessories can be stored.
- Pressure control: Simpson’s Dial-N-Wash® is an adjustable pressure regulator that allows you to select the correct pressure for the desired cleaning application. You can easily change between a higher pressure, medium pressure or lower pressure setting, with a simple twist. It is designed to fit most pressure washer standard spray wands and standard guns with threaded fittings.
- Safety: Safety of operation is enhanced by a thermal relief valve (which helps to prevent internal pump damage) and a trigger lock mechanism (which prevents accidental operation).
- Accessories: Besides the usual owner's manual (opens in a new tab) and documentation to get you promptly started, the Simpson MS60773-S comes with oil, spray gun, pressure regulator, pressure hose, wand and soap hose.
