The STIHL RB 400 DIRT BOSS® pressure washer is engineered for homeowners who demand professional-grade performance and durability for their toughest cleaning tasks. Powered by a robust 196 cc (6.5 hp) engine, this pressure washer delivers an impressive 2,700 PSI of water pressure at 2.7 gallons per minute, generating 7,290 cleaning units – powerful enough to tackle stubborn dirt, grime, and stains on driveways, decks, siding, and vehicles around your Grapevine property.

Built with longevity in mind, the RB 400 features premium components that distinguish it from typical consumer models. The brass manifold pump design, stainless steel valves, and ceramic-coated pistons provide exceptional resistance to wear and corrosion. The cast-iron engine liner adds durability, while the integrated low-oil shutdown feature protects your investment from damage during operation.

User convenience is prioritized with the Easy Start Pump System, which incorporates a pressure relief valve that eliminates back pressure from the pump during startup, ensuring quick and effortless pulls every time. The 25-foot no-kink flex hose provides excellent range and maneuverability, allowing you to clean larger areas without constantly repositioning the machine.

The RB 400 DIRT BOSS® also features a convenient detergent injector system that makes applying cleaning solutions simple and effective. The four-point anti-vibration system reduces operational fatigue and extends the unit’s service life by minimizing vibration during use.

Versatility is another hallmark of this pressure washer, with compatibility for numerous optional accessories including rotary surface cleaners, water brooms, specialized nozzles, hose extensions, gutter cleaners, and STIHL’s professional-grade cleaning agents. For Grapevine residents who need a reliable pressure washer that handles daily cleaning challenges with ease, the DIRT BOSS® delivers professional results with homeowner-friendly design.
