Zoom on the Simpson CM61081

In a nutshell, the Simpson CM61081 is a medium to heavy 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
  • use of detergent and cleaning solutions

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

Power

Powered by a 159 cc engine, its axial cam pump can deliver a pressure of 2800 PSI (around 47 times more than a standard garden hose) and a flow of up to 2.3 GPM (CETA-certified values). Combined, these values mean that the Simpson CM61081 has a cleaning power of 6440 Cleaning Units.

The Simpson 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 0.3 gallon.

Design & Handling

Thanks to its hand truck design and approximate dimensions of D16.5 x W13 x H33.3 in, the Simpson CM61081 offers great mobility. The robust steel tubing frame guarantees longevity of the assembly. The handle adds to the CM61081 convenience of transport.

With a weight of 56 lbs, the unit can be easily maneuvered by most users. Its 159 cc Simpson engine and steel tubing frame all add up to a substantial part of that weight. Nethertheless, thanks to its two 8" never-flat wheels, the CM61081 remains very easy to manipulate and maneuver.

Main Features

The Simpson CM61081 comes with a spray gun, a wand, a pressure hose, 3 nozzles and a detergent injection feature, which are detailed below.

  • Soap injection: While the device doesn't feature a soap tank, detergent supply is ensured by a siphon hose. The detergent will be added automatically to the water when a soap nozzle is attached.
  • Pressure hose: A neat storage for the included 25 ft ⌀1/4" high-pressure hose is facilitated by a set of easy-to-use straps.
  • Spray gun and wand: A side hook enables you to easily store the included classic ergonomic spray gun and its wand.
  • Nozzles: The 3 included nozzles, and the respective surfaces they’re appropriate for, are listed in the table below.
