Description
Zoom on the Stihl RB 800
In a nutshell, the Stihl RB 800 is a heavy duty, commercial pressure washer, which not only offers an all-around versatile cleaning experience, but that also allows:
- precise spot cleaning of hard, unpainted surfaces, reaching elevated areas, and effectively removing stubborn stains
- complete cleaning of hard surfaces, vehicle washing, and surface prep for painting
- mild cleaning for delicate surfaces, and low-pressure cleaning for broader areas
- applying detergents and cleaning agents, and rinsing off surfaces
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 800
With a powerful 429cc (14 hp) engine powering it, the brass triplex pump of this unit are capable of achieving a pressure of 4200 PSI (approximately 70 times greater than that of a standard garden hose) and a flow rate of up to 4 GPM (values claimed by the manufacturer). Corresponding to these values is a cleaning power of 16800 Cleaning Units.
The Kohler CH440 engine of this gas pressure washer is activated by pulling a starter cord, following a traditional approach.
The pressure washer's tank has a maximum capacity of 1.8 gallon for storing gasoline..
Design & Handling
The Stihl RB 800's mobility is greatly enhanced by its hand truck design. The robust steel tubing frame guarantees longevity of the assembly, providing stability and protection for internal components, even under demanding working conditions. The folding handle enhances its mobility, while allowing for a convenient storage.
At 168 lbs, we can't really say that the unit is lightweight, and manually lifting or transporting it could be a significant challenge for users, especially if they need to move it frequently or navigate over uneven terrain. A key role in its final weight is played by its 429cc Kohler CH440 engine, the triplex pump and steel tubing frame. Despite this, the presence of two 13" pneumatic wheels reduces the complexity of moving the RB 800, even on rugged surfaces.
Main Features
The Stihl RB 800
The Stihl RB 800's package includes a spray gun, a wand, a pressure hose, 5 nozzles and a detergent injection feature, with a more detailed description below.
- Soap injection: Even without a built-in soap tank, the device relies on a siphon hose to provide detergent. The Stihl RB 800 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. The detergent is automatically mixed with the water flow by the pressure washer when a soap nozzle is connected.
- Pressure hose: For easy organization, the included 50 ft ⌀3/8" high-pressure hose can be stored on the unit using a set of convenient hooks when it's not in use, ensuring a clutter-free workspace.
- 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 following table provides information on the 5 included nozzles and their recommended surface uses.
