Zoom on the Simpson CM61083

- targeted spot cleaning for hard, unpainted surfaces, reaching elevated areas, and thoroughly removing stubborn stains
- complete cleaning of hard surfaces, vehicle washing, and surface prep for painting
- mild cleaning for delicate surfaces, and low-pressure cleaning for broader areas

Ahead are presented its power characteristics and design, its main features and any other additional features.
Power
Powered by an impressive 210cc engine, its axial cam pump can deliver a pressure of 3400 PSI (around 57 times more than a standard garden hose) and a flow of up to 2.5 GPM (CETA-certified values). With these values combined, the Simpson CM61083 boasts a cleaning power of 8500 Cleaning Units.
To start the CRX 210 engine of this gas-powered washer, users employ the familiar pull-start technique.
Gasoline is stored in a fuel tank with a maximum capacity of 0.7 gallon.
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. The sturdy steel frame ensures the longevity of the assembly, offering stability and protection for internal components, even during rigorous use. The handle adds to the CM61083 convenience of transport.
Weighing 63 lbs, this unit offers a manageable weight that allows for easy handling by most individuals. This weight is largely influenced by the presence of the 210cc CRX 210 engine and a robust steel frame. Nevertheless, the CM61083's two 10" pneumatic wheels ensure it remains easy to maneuver.
Main Features
The Simpson CM61083 comes with a spray gun, a wand, a pressure hose, 4 nozzles and a detergent injection feature, which are detailed below.
- Soap injection: Despite the absence of a soap tank, detergent supply is facilitated through the use of a siphon hose. When a soap nozzle is connected, the pressure washer takes the initiative to mix the detergent with the water flow automatically.
- Pressure hose: The included 25 ft ⌀5/16" high-pressure hose can be neatly stored on the unit when not in use, utilizing a set of convenient hooks for convenient organization.
- Spray gun and wand: A side hook enables you to easily store the included classic ergonomic spray gun and its wand.
- Nozzles: In the table below, you can see the 4 included nozzles alongside their respective recommended surface uses.
