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, unpainted surfaces and high-reach cleaning
  • applying detergent and cleaning solutions

The following sections will present you in detail its power characteristics and design, its main features and all the additional features it has to offer.

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.

The fuel is stored in a tank, which can hold up to 0.24 gallon of gasoline.

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.

With a weight of only 43 lbs, the unit is very easy to carry around. A set of two 6" never-flat wheels also improves the ease of transport of the device.

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 is stored in a 1 gal tank. The Simpson CM60912 includes an automatic soap dilution mechanism, which will dilute the detergent using a 7:1 ratio. If a soap nozzle is attached, the device will proceed to add the detergent to the water automatically.
  • Pressure hose: Using a set of easy-to-use straps, 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: Both the classic ergonomic spray gun and its steel wand may be conveniently stored in a side hook.
  • Nozzles: The 3 included nozzles, and the respective surfaces they’re appropriate for, are listed in the table below.

  • The Simpson CM60912, which can achieve a PSI of up to 2400, falls behind the other gas-powered pressure washers in the $200 to $250 price range.

  • In the aforementioned price range, this washer, with 2 GPM (gallons per minute), is placed on the lower end of the GPM scale. If rinsing away debris most efficiently is your priority, one of the devices with the highest GPM in this price range is the Ryobi RY80544, which can reach up to 2.5 GPM.
  • With 4800 Cleaning Units (PSI x GPM), the CM60912 is on the low end when compared to other similarly priced gas-powered devices. If the highest overall cleaning power is your top priority, the Ryobi RY80544, which can reach up to 7750 Cleaning Units, is one of the most efficient of the devices in the current price range.
