The Honda GCV160 engine of this gas-powered pressure washer gets started by a classic pull-start mechanism.
Gasoline storage is facilitated by a fuel tank with a maximum capacity of 0.25 gallon.
Design & Handling
The Simpson MS60773-S is very mobile, due to its hand truck design and approximate dimensions of D26 x W18 x H35 in. The robust steel frame guarantees longevity of the assembly. The handle adds to the MS60773-S convenience of transport.
The majority of users will be able to maneuver this unit easily, it only weighs 61 lbs. Its 160cc Honda GCV160 engine and steel frame account for a good chunk of that weight. Since the MS60773-S has a set of two 12" never-flat wheels, it is still easily maneuvered and manipulated.
Along with the Simpson MS60773-S itself, the package also includes a spray gun, a wand, a pressure hose, 4 nozzles and a detergent injection feature, which are discussed in further detail 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. If a soap nozzle is attached, the device will proceed to add the detergent to the water automatically.
- 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: Both the classic ergonomic spray gun and its steel wand may be conveniently stored in a side hook.
- Nozzles: The following table illustrates the 4 included nozzles, along with the surfaces which they are the most suitable for.

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, a device which can produce up to 2800 PSI, is on the lower end of the pressure spectrum, among the gas-powered pressure washers in the $300-400 price range. As for the device with the most powerful water stream, in this price range, one of the top products is the Westinghouse WPX3400 with 3400 PSI.
- The achievable water flow of this washer, which reaches 2.3 GPM (gallons per minute) can be described as low, compared to other 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 Lifan LFQ3370, with 3 GPM.
- The MS60773-S ranks as below average in terms of Cleaning Units, compared to gas-powered devices in its price range, reaching only a value of 6440 CU (PSI X GPM). If you consider the highest overall cleaning power as a really important factor, the Lifan LFQ3370 and its 9900 Cleaning Units has one of the highest cleaning efficiency of all the similarly priced 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.
