Designed with high-quality, durable components, the DIRT BOSS® is a high-performance and easy-to-use pressure washer for tough cleaning jobs.
The STIHL RB 400 DIRT BOSS® brings serious cleaning power and lasting durability to the jobs that demand more from a pressure washer. Its 196 cc (6.5 hp) engine delivers 2,700 psi at 2.7 gallons per minute, giving you the muscle to cut through stubborn dirt and buildup. Built for regular use, the brass manifold pump, stainless steel valves, ceramic-coated pistons, and cast-iron engine liner provide durability where it counts. A STIHL-engineered four-point vibration isolation system helps reduce pump vibration for increased unit longevity, while low-oil shutdown helps protect the engine.
The Easy Start Pump System relieves pump pressure for quick, easy starting without hard cord pulls, while the detergent injector system makes it simple to add cleaning solution when the job calls for it. A 25-foot no-kink flex hose gives you room to move without constantly repositioning the machine, and the extended two-piece lance and gun assembly offers added accuracy when cleaning taller areas. A wide range of optional STIHL accessories lets you adapt the RB 400 to different cleaning projects, giving the DIRT BOSS® the versatility to take on tough cleanup day after day.
