Zoom on the Simpson CM61083

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

  • spot cleaning of hard, paintless surfaces and reaching far-away areas
  • intense cleaning of tough, paintless surfaces
  • cleaning of painted or delicate surfaces
  • use of detergent and cleaning solutions

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

Power

Using an impressive 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 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

With its hand truck design and approximate dimensions of D13.5 x W22 x H29.3 in, the Simpson CM61083 provides great mobility. Its sturdy steel frame provides longevity to 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. A major component of its weight are its 212 cc Simpson engine and steel frame. But, as the CM61083 does have a set of two 10" pneumatic wheels, it can be easily maneuvered and manipulated.

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: Detergent is fed in through a siphon hose, since the device lacks a soap tank. The detergent will be added automatically to the water when a soap nozzle is attached.
  • 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: Both the classic ergonomic spray gun and its wand may be conveniently stored in a side hook.
  • 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.

The Simpson CM61083's performance versus other pressure washers

The following charts are provided to give you an idea of how the key specs of the Simpson CM61083 compare to similarly priced pressure washers.

  • With 3400 PSI, the Simpson CM61083 ranks as one that can reach the highest pressure, amongst the gas-powered products that cost between $300 and $400.
  • In the aforementioned price range, the GPM (gallons per minute) of this washer, which can reach 2.5, can be considered in the average. If rinsing away debris most efficiently is your priority, one of the devices with the highest GPM in this price range is the Lifan LFQ3370, which can reach up to 3 GPM.
  • With a rather impressive value of 8500 Cleaning Units (PSI x GPM), the CM61083 has a higher cleaning efficiency compared to similarly priced devices. If you are after the highest overall cleaning power, the Lifan LFQ3370 with its 9900 Cleaning Units is one of the products that can achieve the highest cleaning efficiency in this price range.
