Just setup and you are ready to clean. The Clean Machine features a 149cc SIMPSON OHV engine paired with an OEM Technologies axial cam pump.

Zoom on the Simpson CM60912

In a nutshell, the Simpson CM60912 is a medium duty pressure washer, which not only offers an all-around versatile cleaning experience, but that also allows:

  • spot cleaning of hard, paintless surfaces and reaching far-away areas
  • applying detergent and cleaning solutions

Its power characteristics and design, its main features and all its additional features are presented ahead.

Power

Its axial cam pump, which utilizes a 149 cc engine, may deliver a pressure of up to 2400 PSI (almost 40 times more than a standard garden hose) and a flow of up to 2 GPM. These values correspond to a cleaning power of 4800 Cleaning Units.

A classic pull-start mechanism is responsible for starting the gas-powered pressure washer’s Simpson engine.

Gasoline is stored in a fuel tank with a maximum capacity of 0.24 gallon.

Design & Handling

With its hand truck design and approximate dimensions of D16 x W12 x H32 in, the Simpson CM60912 provides great mobility. The robust steel frame guarantees longevity of the assembly. The folding handle enhances its mobility, while allowing for a convenient storage.

Standing at only 43 lbs, this model can be carried around very easily. On top of its light weight, the transportability and easy of use of this model is further improved by the addition of two 6" never-flat wheels.

Main Features

Along with the Simpson CM60912 itself, the package also includes a spray gun, a wand, a pressure hose, 3 nozzles and a detergent injection feature, which are discussed in further detail below.

  • Soap injection: Detergent storage is ensured by a 1 gal tank. The Simpson CM60912 includes an automatic soap dilution mechanism, which will dilute the detergent using 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 easy-to-use straps.
  • Spray gun and wand: The included classic ergonomic spray gun and its steel wand can be easily stored in a side hook.
  • Nozzles: The 3 nozzles included with the device, and the respective surfaces which they’re the most suitable for, are shown in the following table.

The Simpson CM60912's performance versus other pressure washers

The following charts are provided to give you an idea of how the key specs of the Simpson CM60912 compare to similarly priced pressure washers.

  • The Simpson CM60912, which can achieve a PSI of up to 2400, falls behind the other gas-powered pressure washers in the $165 to $285 price range. If your priority is the highest possible power of the water stream, in this price range, we suggest checking out the Westinghouse WPX3200, which reaches up to 3200 PSI.
  • In the aforementioned price range, this washer, with 2 GPM (gallons per minute), is placed on the lower end of the GPM scale. 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 Westinghouse WPX3200, with 2.5 GPM.
  • Amongst similarly priced gas-powered devices, the 4800 Cleaning Units (PSI x GPM) of the CM60912 rank as low. If you consider the highest overall cleaning power as a really important factor, the Westinghouse WPX3200 and its 8000 Cleaning Units has one of the highest cleaning efficiency of all the similarly priced units.

Price comparison

As you can see from this interactive chart, when compared to other gas-powered washers between 4300 and 5200 Cleaning Units, the Simpson CM60912 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.
