Description
Zoom on the Simpson CM61081
The Simpson CM61081, a medium to heavy duty pressure washer, gives its user an all-around versatile cleaning experience, topped off by the following features:
- spot cleaning of hard, paint-free surfaces and out-of-reach areas
- use of 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
With a 159 cc engine, its axial cam pump delivers a pressure of 2800 PSI (roughly 47 times more than a standard garden hose) and a flow of up to 2.3 GPM (CETA-certified values), resulting in the Simpson CM61081's cleaning power of 6440 Cleaning Units.
The Simpson engine of this gas-powered pressure washer relies on an old-school pull-start mechanism to get started.
The fuel is stored in a tank, which can hold up to 0.3 gallon of gasoline.
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.
Weighing 56 lbs, the unit is easy to maneuver by most people. A major component of its weight are its 159 cc Simpson engine and steel tubing frame. However, the two 8" never-flat wheels allow the CM61081 to be easily manipulated and maneuvered.
