Zoom on the Stihl RB 600
In summary, the Stihl RB 600 is a heavy duty, commercial pressure washer, that offers an all-around versatile cleaning experience, and also:
- spot cleaning of hard, paintless surfaces and reaching far-away areas
- intense cleaning of hard, unpainted surfaces
- cleaning of painted or delicate surfaces
- use of detergent and cleaning solutions
Ahead are presented its power characteristics and design, its main features and any other additional features.
Powered by an impressive 208 cc (7 hp) engine, its brass triplex pump can deliver a pressure of 3200 PSI (around 53 times more than a standard garden hose) and a flow of up to 3 GPM (values claimed by the manufacturer). Combined, these values mean that the Stihl RB 600 has a cleaning power of 9600 Cleaning Units.
A classic pull-start mechanism is responsible for starting the gas-powered pressure washer’s Kohler CH270 engine.
A fuel tank with a maximum capacity of 1 gallon is used to store gasoline.
Design & Handling
Thanks to its hand truck design and approximate dimensions of D32.8 x W29 x H42 in, the Stihl RB 600 offers great mobility. The robust and sturdy steel tubing frame offers longevity to the assembly. The folding handle enhances its mobility, while allowing for a convenient storage.
The unit's weight of 118 lbs renders its carrying and transportation challenging, as it is far from lightweight. Its 208 cc Kohler CH270 engine, the triplex pump and steel tubing frame are mainly responsible for its heavy weight. However, the device’s two 13" pneumatic wheels play a key role in its maneuverability, as they allow it to be manipulated smoothly.
The Stihl RB 600 comes with a spray gun, a wand, a pressure hose, 5 nozzles and a detergent injection feature, which are detailed below.
- Soap injection: Detergent is fed in through a siphon hose, since the device lacks a soap tank. As the Stihl RB 600 doesn’t include a soap dilution mechanism, the user must provide a correctly diluted detergent before proceeding to use it. When a soap nozzle is connected, the detergent will be added automatically to the water.
- Pressure hose: Using a set of convenient hooks, the included 40 ft ⌀3/8" high-pressure hose can be easily stored on the unit when it is not running.
- Spray gun and wand: The included classic ergonomic spray gun and its wand can be easily stored in a side hook. The gun features a rotating auxiliary side handle to further improve the comfort of both left and right-handed users.
- Nozzles: The table below shows you the 5 included nozzles, as well as the surfaces they're the most appropriate for.

Had to replace the injector 3 times and the unloaded valve once in 1 year, maybe 8 to 10 houses. Both parts have a spring loaded one way check valve that appears to be made from mild steel. The injector spring and ball corroded to the point that the spring broke. Also, the injector has no adjustment.
The unloaded valve also has a similar setup and it also corroded to the point of not working. This part only sees water,, no chemicals. The injector gets bleach and house wash soap diluted..
Totally unacceptable, I’ve been using washers for 30 years, and my last one was a mi t m who make these for stihl, same chemicals no issues.
