Description
Zoom on the Stihl RB 600
The Stihl RB 600, a heavy duty, commercial pressure washer, gives its user an all-around versatile cleaning experience, topped off by the following features:
- spot cleaning of hard, paint-free surfaces and out-of-reach areas
- intense cleaning of hard, unpainted surfaces
- cleaning of painted and fragile surfaces
- applying detergent and cleaning solutions
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
The Stihl RB 600
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.
The Kohler CH270 engine of this gas-powered pressure washer relies on an old-school pull-start mechanism to get started.
Gasoline is stored in a fuel tank with a maximum capacity of 1 gallon.
Design & Handling
The Stihl RB 600 offers superb mobility, with a hand truck design and approximate dimensions of D32.8 x W29 x H42 in. 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 maneuverability, since they provide a smooth method of manipulation on the job.
Main Features
The Stihl RB 600
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. The Stihl RB 600 is not equipped with a soap dilution mechanism, and thus, it is up to the user to ensure the detergent’s correct dilution ratio when using it. Whenever a soap nozzle is connected, the detergent is automatically added to the water.
- Pressure hose: The 40 ft ⌀3/8" high-pressure hose, which is included with the device, can be stored neatly on the unit itself when idle, using 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. The gun features a rotating auxiliary side handle to further improve the comfort of both left and right-handed users.
- Nozzles: The 5 included nozzles, and the respective surfaces they’re appropriate for, are listed in the table below.
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.
