Rolling / Main BrushUnknown

Downgraded per Phase 9 exact-model-scope re-audit: eufy's own Amazon listing title ("eufy Replacement Roller Brush | for 11S series, 15C, ... G20") uses "11S series" as a generic, unqualified grouping — it does not name "11S Plus" specifically, and this project has repeatedly found that Plus/Hybrid-suffixed eufy models use different parts than their base model. Absence of an explicit name isn't compatibility evidence for this variant. May still be compatible in practice — just not confirmed from this source.
