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

Power

The Simpson CM61083 in use

The Simpson CM61083

The Simpson CM61083's axial cam pump, powered by an impressive 212 cc engine, can provide a pressure of up to 3400 PSI (approximately 57 times more than a standard garden hose) and a flow of up to 2.5 GPM (CETA-certified values). The Simpson CM61083 thus has a cleaning power of 8500 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 0.7 gallon.

Design & Handling

The Simpson CM61083 offers superb mobility, with a hand truck design and approximate dimensions of D13.5 x W22 x H29.3 in. The robust and sturdy steel frame offers longevity to the assembly. The handle adds to the CM61083 convenience of transport.

Weighing 63 lbs, the unit is easy to maneuver by most people. Its 212 cc Simpson engine and steel frame all add up to a substantial part of that weight. However, the two 10" pneumatic wheels allow the CM61083 to be easily manipulated and maneuvered.

Main Features

The Simpson CM61083

Along with the Simpson CM61083 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. If a soap nozzle is attached, the device will proceed to add the detergent to the water automatically.
  • Pressure hose: The 25 ft ⌀5/16" high-pressure hose, which is included with the device, can be stored neatly on the unit itself when idle, using a set of convenient hooks.
  • Spray gun and wand: The included classic ergonomic spray gun and its wand can be easily stored in a side hook.
  • Nozzles: The 4 included nozzles, and the respective surfaces they’re appropriate for, are listed in the table below.

The Simpson CM61083's performance versus other pressure washers

The following charts are provided to give you an idea of how the key specs of the Simpson CM61083 compare to similarly priced pressure washers.

  • The Simpson CM61083, with a max water pressure of 3400 PSI, has one of the highest PSI values of the gas-powered products in the $300-400 price range.
  • In the aforementioned price range, the 2.5 GPM (gallons per minute) of this washer makes it one of the better performing units in terms of the delivered volume of water. 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 3200, with 2.8 GPM.
  • Boasting with 8500 Cleaning Units (PSI X GPM), the CM61083 is one of the more efficient devices in its respective price range. If you consider the highest overall cleaning power as a really important factor, the Predator 3200 and its 8960 Cleaning Units has one of the highest cleaning efficiency of all the similarly priced units.

It can therefore be a really good buy if you're looking to acquire a budget pressure washer.
