Description
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, unpainted surfaces or high reach areas
- intense cleaning of hard, unpainted surfaces
- cleaning of painted or delicate surfaces
- applying detergent and cleaning solutions
Ahead are presented its power characteristics and design, its main features and any other additional features.
Power
The Stihl RB 600
The Stihl RB 600's brass triplex pump, powered by an impressive 208 cc (7 hp) engine, can provide a pressure of up to 3200 PSI (approximately 53 times more than a standard garden hose) and a flow of up to 3 GPM (values claimed by the manufacturer). The Stihl RB 600 thus 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.
Gasoline storage is facilitated by a fuel tank with a maximum capacity of 1 gallon.
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 steel tubing frame guarantees longevity of the assembly. The folding handle enhances its mobility, while allowing for a convenient storage.
The device weighs 118 lbs and thus, is far from lightweight. Transporting and manually lifting it may therefore pose a challenge. A key role in its final weight is played by its 208 cc Kohler CH270 engine, the triplex pump and steel tubing frame. However, the unit’s two 13" pneumatic wheels are crucial to its maneuvrability, since they provide a smooth method of manipulation on the job.
Main Features
The Stihl RB 600
Along with the Stihl RB 600 itself, the package also includes a spray gun, a wand, a pressure hose, 5 nozzles and a detergent injection feature, which are discussed in further detail below.
- Soap injection: While the device doesn't feature a soap tank, detergent supply is ensured by a siphon hose. 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. If a soap nozzle is attached, the device will proceed to add the detergent to the water automatically.
- Pressure hose: A neat storage for the included 40 ft ⌀3/8" high-pressure hose is facilitated by a set of convenient hooks.
- Spray gun and wand: A side hook enables you to easily store the included classic ergonomic spray gun and its wand. A rotating auxiliary side handle further improves both left-handed and right-handed users' comfort.
- Nozzles: The 5 nozzles included with the device, and the respective surfaces which they’re the most suitable for, are shown in the following table.
0° | 15° | 25° | 40° | Soap |

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.
