Zoom on the Simpson CM61083

In a nutshell, the Simpson CM61083 is a heavy duty, commercial pressure washer that allows:

  • spot cleaning of hard, unpainted surfaces or high reach areas
  • intense cleaning of hard, unpainted surfaces
  • cleaning of painted and frail surfaces
  • application of detergent and cleaning solutions

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

Power

Using a powerful 212 cc 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 Simpson engine of this gas-powered pressure washer relies on an old-school pull-start mechanism to get started.

Gasoline storage is facilitated by a fuel tank with a maximum capacity of 0.7 gallon.

Design & Handling

With its hand truck design and approximate dimensions of D13.5 x W22 x H29.3 in, the Simpson CM61083 provides great mobility. The robust steel frame guarantees longevity of the assembly. The handle adds to the CM61083 convenience of transport.

The majority of users will be able to maneuver this unit easily, it only weighs 63 lbs. One of the largest contributors to its weight are its 212 cc Simpson engine and its steel frame. Nethertheless, thanks to its two 10" pneumatic wheels, the CM61083 remains very easy to manipulate and maneuver.

Main Features

The Simpson CM61083's package includes a spray gun, a wand, a pressure hose, 4 nozzles and a detergent injection feature, with a more detailed description below.

  • Soap injection: Detergent is fed in through a siphon hose, since the device lacks a soap tank. The detergent is automatically added to the water when a soap nozzle is connected.
  • Pressure hose: The included 25 ft ⌀5/16" high-pressure hose can be neatly stored on the unit when idle thanks to a set of convenient hooks.
  • Spray gun and wand: A side hook enables you to easily store the included classic ergonomic spray gun and its wand.
  • Nozzles: The following table illustrates the 4 included nozzles, along with the surfaces which they are the most suitable for.
