⚠ Common mistakes to avoid
- Confirm the part matches your exact model number before buying — Dyson reuses parts across lines.
- Never wash a filter unless it's marked washable, and dry it fully (24h) before refitting.
- Don't force the part — if it resists, check alignment before applying pressure.
- Always disconnect power (or remove the battery) before any internal work.
The Dyson V8 side brush should be replaced Every 3-6 months under normal use — sooner with pets or daily heavy use. Signs it's due: Poor edge cleaning, brush not spinning.
