Description
Zoom on the Stihl RB 800
The Stihl RB 800 is a heavy duty, commercial pressure washer, that provides its users with an all-around versatile cleaning experience, and enables:
- spot cleaning of hard, paintless surfaces and reaching far-away areas
- intense cleaning of tough, paintless surfaces
- cleaning of painted or delicate surfaces
- use of detergent and cleaning solutions
Its power characteristics and design, its main features and all its additional features are presented ahead.
Power
The Stihl RB 800
Its brass triplex pump, which utilizes a powerful 429cc (14 hp) engine, may deliver a pressure of up to 4200 PSI (almost 70 times more than a standard garden hose) and a flow of up to 4 GPM. These values correspond to a cleaning power of 16800 Cleaning Units.
This gas-powered pressure washer’s Kohler CH440 engine is started by a traditional pull-start mechanism.
A fuel tank with a maximum capacity of 1.8 gallon is used to store gasoline.
Design & Handling
The Stihl RB 800 is very mobile, due to its hand truck design and approximate dimensions of D33.5 x W31 x H45.8 in. Its sturdy steel tubing frame provides longevity to the assembly. The folding handle enhances its mobility, while allowing for a convenient storage.
This model weighs 168 lbs. For this reason, it cannot be called lightweight and thus, carrying and transporting it might be somewhat challenging. Its 429cc Kohler CH440 engine, the triplex pump and steel tubing frame add up to a large chunk of the device's weight. However, the unit is mobile thanks to its two 13" pneumatic wheels, which add to its movability and allow it to be manipulated smoothly on the job.
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: Detergent is fed in through a siphon hose, since the device lacks a soap tank. 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 added to the water when a soap nozzle is connected.
- Pressure hose: A neat storage for the included 50 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 following table illustrates the 5 included nozzles, along with the surfaces which they are the most suitable for.
0° | 15° | 25° | 40° | Soap | |
|---|---|---|---|---|---|
| Concrete, brick, masonry | Use with caution | Suitable | Suitable | Suitable | Suitable |
