Zoom on the Simpson CM61083
In summary, the Simpson CM61083 is a heavy duty pressure washer, which provides:
- focused spot cleaning on hard, unpainted surfaces, accessing high spots, and efficiently eliminating stubborn stains
- overall cleaning of hard surfaces, washing vehicles, and prepping surfaces for painting
- gentle cleaning of delicate surfaces, and low pressure cleaning of larger areas
- applying detergents or chemicals, and rinsing surfaces afterward
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
Utilizing an impressive 210cc engine, this machine's axial cam pump can deliver a pressure of 3400 PSI (around 57 times stronger than a standard garden hose) and a flow rate of up to 2.5 GPM (CETA-certified values). Thus, the Simpson CM61083 achieves a cleaning power of 8500 Cleaning Units.
The CRX 210 engine of this gas pressure washer is activated by pulling a starter cord, following a traditional approach.
Gasoline is stored in 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 durable steel frame of the assembly ensures its longevity, providing stability and shielding internal components from damage, even in tough conditions. The handle adds to the CM61083 convenience of transport.
At 63 lbs, this unit is light enough for easy handling, yet substantial enough to provide stability during operation. This substantial weight can be partially attributed to the incorporation of the 210cc CRX 210 engine and a resilient steel frame. Even so, the CM61083's two 10" pneumatic wheels maintain easy maneuverability.
Main Features
Along with the Simpson CM61083 itself, the package also includes a spray gun, a wand, a pressure hose, 4 nozzles and a detergent injection feature, which are discussed in further detail below.
- Soap injection: Even without a built-in soap tank, the device relies on a siphon hose to provide detergent. Connection of a soap nozzle triggers the pressure washer to automatically incorporate the detergent into the water stream.
- Pressure hose: The unit comes equipped with an included 25 ft ⌀5/16" high-pressure hose, which can be neatly stored on the unit when idle, thanks to a set of convenient hooks, ensuring easy access and organization.
- Spray gun and wand: Both the classic ergonomic spray gun and its wand may be conveniently stored in a side hook.
- Nozzles: Refer to the table below for details on the 4 included nozzles and their recommended surface applications.

Other Features

- Safety: Safety of operation is enhanced by a trigger lock mechanism (which prevents accidental operation) and a thermal relief valve (which helps to prevent internal pump damage).
- Accessories: Included with the Simpson CM61083 are also the owner's manual (opens in a new tab) and some basic documentation to get you promptly started, along with several accessories, such as soap hose, pressure hose, oil, spray gun and wand.
