FlexiArm Design Side Brush
UnknownFlexiArm functionality does not establish a distinct replacement brush. Previously not_compatible (manufacturer_confirmed) on the strength of Roborock's support article (https://support.roborock.com/hc/en-us/articles/33954114436761-What-is-the-difference-among-of-S8-Pro-Ultra-S8-Max-Ultra-and-S8-MaxV-Ultra), which only says S8 Max Ultra and S8 MaxV Ultra "are equipped with the FlexiArm Design Side Brush" — a feature difference, not a statement about which replacement brush fits. No official FlexiArm-specific replacement brush product was found, and Roborock's standard side brush (SKU RR-BS5-Q85MaxPlus-M2) names S8 Max Ultra and S8 MaxV Ultra directly. Whether this is a real separate part is under audit.
Compatibility is not confirmed. The previously cited Roborock comparison article describes robot features, not replacement-part fit. The Edgewise accessory listing names S8 Max Ultra and S8 MaxV Ultra; omission of this model does not establish incompatibility.
