Details

The STIHL RB 800 Petrol Water Blaster is the most powerful in the STIHL range, designed for intensive, everyday commercial use. Built with premium components, it’s ideal for tackling the toughest cleaning jobs with ease.

Maximum Power: A high-performance 10.5 kW (14 hp) petrol engine delivers up to 290 bar of pressure, making it suitable for heavy-duty cleaning across large, heavily soiled surfaces. A robust frame protects the engine and pump in demanding conditions.

Control & Efficiency: Pressure can be easily adjusted at the pump to suit different surfaces, helping avoid damage while maintaining strong cleaning performance. The integrated detergent injector draws cleaning agents from external containers for added efficiency.

Comfort & Practicality: The spray lance features a second handle for better control and comfort during longer jobs, along with a convenient holder for easy pauses. The machine is easy to start and designed to be manoeuvred without hassle.

Storage & Flexibility: Onboard storage keeps nozzles and the spray lance organised, while the foldable guide bar supports compact transport and storage. Quick-release couplings make swapping accessories fast, with a wide range of compatible tools available to suit different cleaning tasks.
