Maximum Cleaning Power for Professional Applications

The STIHL RB 800 Gasoline Pressure Washer is designed for professionals who demand uncompromising cleaning performance every day. As the flagship pressure washer in the STIHL lineup, the RB 800 combines industrial-grade construction with exceptional water pressure to tackle the most challenging cleaning tasks in construction, agriculture, transportation, municipal maintenance, and commercial property care.

Powered by a high-output 429cc gasoline engine, the RB 800 generates an impressive 4,200 PSI of water pressure, providing the power needed to remove stubborn mud, grease, oil, paint residue, mildew, heavy dirt, and industrial grime from virtually any surface. Whether cleaning heavy machinery, commercial vehicles, sidewalks, warehouses, loading docks, or large outdoor spaces, this pressure washer delivers professional results with outstanding efficiency.

Built to withstand years of demanding use, the RB 800 features a commercial-grade pump with premium internal components, a cast-iron cylinder liner, corrosion-resistant stainless steel valves, and a rugged frame engineered for harsh working environments. STIHL’s Easy Start Pump System relieves pump pressure during startup, making engine starts effortless while reducing wear on the recoil starter.

Operator comfort is equally impressive. The four-point vibration isolation system minimizes pump vibration to reduce fatigue during extended operation, while the ergonomic spray gun includes a secondary support handle that offers increased control during high-pressure cleaning. The included steel-braided high-pressure hose resists kinks, abrasion, and bursting, ensuring dependable performance under demanding conditions.

The RB 800 also features premium stainless steel quick-connect spray nozzles, a dedicated brass detergent nozzle, convenient detergent injection, easy-access water connections, and compatibility with a wide range of STIHL accessories, including rotary surface cleaners, water brooms, extension wands, turbo nozzles, and hose extensions.

When maximum cleaning power, long-term durability, and commercial reliability are essential, the STIHL RB 800 stands at the top of its class.
