A few sources mention hair or debris causing issues in the auto-empty evacuation path or channel, sometimes requiring cleaning or more frequent runs to prevent buildup. Overall it’s manageable but not immune to clogs in heavy hair environments.
Some commentary notes that certain newer Dyson rollers can allow hair to wrap around side gaps/axles even when brush-wrap is minimized, creating occasional cleanup at the ends. This is presented as a nuisance rather than a dealbreaker, especially compared with older “chunkier” rollers that behave differently.
