The Simpson MegaShot MS60805-S is a gas-powered pressure washer offering a maximum water pressure of 3000 PSI and flow of 2.4 GPM. (Read full specs)
Zoom on the Simpson MS60805-S
In a nutshell, the Simpson MS60805-S is a heavy duty pressure washer that allows:
- spot cleaning of hard, paint-free surfaces and out-of-reach areas
- intense cleaning of tough, paintless surfaces
- cleaning of painted and fragile surfaces
- applying detergent and cleaning solutions
Using a 160 cc (4.4 hp) engine, its axial cam pump delivers a pressure of up to 3000 PSI (roughly 50 times more than a standard garden hose) and a flow of up to 2.4 GPM (values claimed by the manufacturer). Together, the values result in a cleaning power of 7200 Cleaning Units.
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
With its hand truck design and approximate dimensions of D26 x W18 x H35 in, the Simpson MS60805-S provides great mobility. Its sturdy steel frame provides longevity to the assembly. The handle adds to the MS60805-S convenience of transport.
With a weight of 56 lbs, the unit can be easily maneuvered by most users. Its 160 cc Honda GCV160 engine and steel frame account for a good chunk of that weight. However, the two 12" never-flat wheels allow the MS60805-S to be easily manipulated and maneuvered.
Along with the Simpson MS60805-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: Detergent storage is ensured by a dedicated tank. The Simpson MS60805-S includes an automatic soap dilution mechanism, which will dilute the detergent using a 7:1 ratio. Whenever a soap nozzle is connected, the detergent is automatically added to the water.
- Pressure hose: Using a set of convenient hooks, the included 25 ft ⌀1/4" high-pressure hose can be easily stored on the unit when it is not running.
- Spray gun and wand: A side hook allows for an easy storage of the included classic ergonomic spray gun and its steel wand.
- Nozzles: The 4 included nozzles, and the respective surfaces they’re appropriate for, are listed in the table below.

The Simpson MS60805-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 MS60805-S compare to similarly priced pressure washers.
- With a maximum pressure output of 3000 PSI, the Simpson MS60805-S finds itself in the expected pressure range among gas-powered units that cost between $300 and $400. If your priority is the highest possible power of the water stream, in this price range, we suggest checking out the Stanley SXPW3425, which reaches up to 3400 PSI.
- As this washer can produce a flow of water of 2.4 GPM (gallons per minute), it is average in terms of water volume for the above-mentioned 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.
- The 7200 Cleaning Units (PSI x GPM), of the MS60805-S sit at an average, in reference to other gas-powered units of similar price. If the highest overall cleaning power is your top priority, the Westinghouse WPX3400, which can reach up to 8840 Cleaning Units, is one of the most efficient of the devices in the current price range.
As you can see from this interactive chart, when compared to other gas-powered washers between 7000 and 7500 Cleaning Units, the Simpson MS60805-S is on the average side of the price range.
Therefore, this pressure washer nicely fits in the expected budget for this kind of cleaning power.
