When to replace brushes and bags

Brand intervals are a starting point, not a fit verdict.

1. Side brush: often 3–6 months if the tufts are bent.
2. Main brush: 6–12 months, sooner on long-hair floors.
3. Filter: rinse on the official cadence; replace when the frame or media collapses.
4. Dock bags: replace when the station says full — do not reuse torn bags.
