Roborock S6
Quick answer
Roborock S6 has manufacturer-confirmed compatibility with 5-Arm Side Brush (standard), Bristle+Rubber Combo Brush (S4/S5/S6 generation), and Washable HEPA Filter (S4/S5/S6 generation). Compatibility with Main / Roller Brush (S7 generation) is NOT confirmed — Roborock's own support site confirms the S7 generation main brush is a new design not shared with S4/S5/S6.
