Zoom on the Simpson CM61083

The Simpson CM61083 is a heavy duty, commercial pressure washer, and enables:

  • spot cleaning of hard, paintless surfaces and reaching far-away areas
  • intense cleaning of hard, unpainted surfaces
  • cleaning of painted and frail surfaces
  • 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

The Simpson CM61083 in use

The Simpson CM61083

Using a powerful 210cc engine, its axial cam pump delivers a pressure of up to 3400 PSI (roughly 57 times more than a standard garden hose) and a flow of up to 2.5 GPM (CETA-certified values). Together, the values result in a cleaning power of 8500 Cleaning Units.

The CRX 210 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 0.7 gallon.

Design & Handling

The Simpson CM61083 is very mobile, due to its hand truck design and approximate dimensions of D13.5 x W22 x H29.3 in. The strong steel frame assures assembly longevity. The handle adds to the CM61083 convenience of transport.

With a weight of 63 lbs, the unit can be easily maneuvered by most users. Its 210cc CRX 210 engine and steel frame account for a good chunk of that weight. Nethertheless, thanks to its two 10" pneumatic wheels, the CM61083 remains very easy to manipulate and maneuver.
