Zoom on the Simpson MS60773-S
In summary, the Simpson MS60773-S is a medium to heavy duty pressure washer, which provides:
- spot cleaning of hard, paint-free surfaces and out-of-reach areas
- intense cleaning of tough, paintless surfaces
- cleaning of painted and fragile surfaces
- use of detergent and cleaning solutions
Its axial cam pump, which utilizes a 160 cc (4.4 hp) engine, may deliver a pressure of up to 2800 PSI (almost 47 times more than a standard garden hose) and a flow of up to 2.3 GPM. These values correspond to a cleaning power of 6440 Cleaning Units.
This gas-powered pressure washer’s Honda GCV160 engine is started by a traditional pull-start mechanism.
The fuel is stored in a tank, which can hold up to 0.25 gallon of gasoline.
Design & Handling
The Simpson MS60773-S offers superb mobility, with a hand truck design and approximate dimensions of D26 x W18 x H35 in. The strong steel frame assures assembly longevity. 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 account for a good chunk of that weight. But, as the MS60773-S does have a set of two 12" never-flat wheels, it can be easily maneuvered and manipulated.
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 detergent is diluted with a 7:1 ratio by the Simpson MS60773-S's automatic soap dilution mechanism. 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 table below shows you the 4 included nozzles, as well as the surfaces they're the most appropriate for.

- Onboard storage: The Simpson MS60773-S features a handy storage area, which allows you to neatly store nozzles and accessories and be always prepared by having everything needed at hand.
- 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 trigger lock mechanism (which prevents accidental operation) and a thermal relief valve (which helps to prevent internal pump damage).
- Accessories: The Simpson MS60773-S comes with an owner's manual (opens in a new tab) and some basic documentation to get you quickly started. On top of that, you also get pressure regulator, spray gun, wand, oil, pressure hose and soap hose.

The Simpson MS60773-S's performance versus other pressure washers
The following charts are provided to give you an idea of how the key specs of the Simpson MS60773-S compare to similarly priced pressure washers.
- The Simpson MS60773-S and its 2800 PSI, ranks amongst gas-powered pressure washers with a comparably low pressure output, considering the units that cost between $275 and $400. If your priority is the highest possible power of the water stream, in this price range, we suggest checking out the Westinghouse WPX3400, which reaches up to 3400 PSI.
- This washer, with a GPM of 2.3 (gallons per minute) has a somewhat lower water flow value compared to devices in its price range. If being able to rinse away debris as efficiently as possible is your priority, one of the products with the highest GPM in this price range is the Predator 3100, with 2.8 GPM.
- Amongst similarly priced gas-powered devices, the 6440 Cleaning Units (PSI x GPM) of the MS60773-S rank as low. In case you are looking for the highest overall cleaning power, in this price range, one of the current champions is the Predator 3200 and its 8960 Cleaning Units.
As you can see from this interactive chart, when compared to other gas-powered washers between 6000 and 6500 Cleaning Units, the Simpson MS60773-S is on the expensive side of the price range.
While certainly not the cheapest of its cleaning power range, purchasing it could most likely also mean enjoying the reliability of a high-end product.
