Whether it’s greasy farm equipment, stained aluminum siding, or a dirty truck, the STIHL RB 600 is ready to rock. It features 3,200 psi of water pressure and 208 cc engine. Its pump components are made of premium commercial-grade Triplex to reinforce its durability. Plus, with the easy start pump system you can start the washer without difficulty or back pressure from the pump. (source: Stihl (opens in a new tab))

Zoom on the Stihl RB 600

In a nutshell, the Stihl RB 600 is a heavy duty, commercial pressure washer, which not only offers an all-around versatile cleaning experience, but that also allows:

  • spot cleaning of hard, unpainted surfaces or high reach areas
  • thorough cleaning of hard, paint-free surfaces
  • cleaning of painted or delicate surfaces
  • application of 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 in use

The Stihl RB 600

With an impressive 208 cc (7 hp) engine, its brass triplex pump delivers a pressure of 3200 PSI (roughly 53 times more than a standard garden hose) and a flow of up to 3 GPM (values claimed by the manufacturer), resulting in the Stihl RB 600's cleaning power of 9600 Cleaning Units.

This gas-powered pressure washer’s Kohler CH270 engine is started by a traditional pull-start mechanism.

Gasoline is stored in a fuel tank with a maximum capacity of 1 gallon.

Design & Handling

The Stihl RB 600 is very mobile, due to its hand truck design and approximate dimensions of D32.8 x W29 x H42 in. The strong steel tubing frame assures assembly longevity. 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. The main contributor to its weight are its 208 cc Kohler CH270 engine, the triplex pump and steel tubing frame. However, its two 13" pneumatic wheels play an important part in its maneuvrability, as they allow for a smooth 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: Even though the device doesn't have a soap tank, detergent is supplied by a siphon hose. It must be noted that the Stihl RB 600 doesn’t come with a soap dilution mechanism. Therefore, you must always make sure that your detergent is correctly diluted. The detergent will be added automatically to the water when a soap nozzle is attached.
  • 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. 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.

The following charts are provided to give you an idea of how the key specs of the Stihl RB 600 compare to similarly priced pressure washers.

  • The Stihl RB 600, a device which can produce up to 3200 PSI, is on the lower end of the pressure spectrum, among the gas-powered pressure washers in the $900-1000 price range. As for the device with the most powerful water stream, in this price range, one of the top products is the Lifan LFQ4515E-CA with 4500 PSI.
  • In comparison to other devices in the above-mentioned price range, this washer and its 3 GPM (gallons per minute), has one of the lower GPM values. If maximum rinsing efficiency is your top priority, one of the devices with the highest water flow in the same price range is the Predator 4400, with a GPM of 4.2.
  • Amongst similarly priced gas-powered devices, the 9600 Cleaning Units (PSI x GPM) of the RB 600 rank as low. When it comes to the highest overall cleaning power in the current price range, one of the products at the very top currently is the Predator 4400 and its 18480 Cleaning Units.
