Zoom on the Simpson CM61083

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

  • spot cleaning of hard, paint-free surfaces and out-of-reach areas
  • intense cleaning of hard, unpainted surfaces
  • cleaning of painted and fragile surfaces
  • application 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

Its axial cam pump, which utilizes an impressive 212 cc engine, may deliver a pressure of up to 3400 PSI (almost 57 times more than a standard garden hose) and a flow of up to 2.5 GPM. These values correspond to a cleaning power of 8500 Cleaning Units.

The Simpson engine of this gas-powered pressure washer gets started by a classic pull-start mechanism.

A fuel tank with a maximum capacity of 0.7 gallon is used to store gasoline.

Design & Handling

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

Most users can maneuver this model easily, as it weighs just 63 lbs. A major component of its weight are its 212 cc Simpson engine and steel frame. However, the two 10" pneumatic wheels allow the CM61083 to be easily manipulated and maneuvered.

Main Features

The Simpson CM61083 in use

The Simpson CM61083

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. When a soap nozzle is connected, the detergent will be added automatically to the water.
  • 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 allows for an easy storage of the included classic ergonomic spray gun and its wand.
  • Nozzles: The 4 nozzles included with the device, and the respective surfaces which they’re the most suitable for, are shown in the following table.
