Description

Designed to handle frequent, demanding outdoor cleaning tasks, this gas pressure washer delivers strong water pressure and consistent flow for removing stubborn dirt from driveways, decks, siding, fencing, and equipment. With rugged components and user‑friendly features, the RB 400 bridges the gap between residential and professional‑grade performance.

Key Features

  • Gas‑powered 196cc engine delivers up to 2700 PSI for heavy‑duty cleaning
  • 2.7 GPM water flow provides faster, more efficient surface coverage
  • Easy Start pump system reduces starting effort and pull resistance
  • Brass manifold pump with ceramic‑coated pistons for enhanced durability
  • Low‑oil shutdown helps protect the engine during operation
  • 25ft no‑kink high‑pressure hose allows extended reach without moving the unit
  • Two‑piece lance and spray gun assembly improves control and accuracy
  • Detergent injector system supports deeper cleaning on tough surfaces

Why It’s a Smart Pick

The STIHL® RB 400 DIRT BOSS® stands out as a powerful step‑up option for users who want more durability and cleaning strength than entry‑level pressure washers. Its robust pump construction, higher PSI and GPM output, and protective engine features make it a reliable choice for frequent residential use where performance and longevity matter.
