Possible Causes

Dirty or old filters, Dust accumulation in cyclone, Use in damp environments, Organic debris in bin

How to Fix / Troubleshooting

Safety first: Turn the robot OFF before servicing. Do not use scented cleaners inside the machine.

  • Clean or replace filters: Wash washable filters as per Dyson instructions and allow to dry fully. Replace non‑washable filters with genuine Dyson parts.
  • Clean bin and cyclone: Wipe the bin with a dry or slightly damp cloth (if allowed by Dyson) and let it dry completely.
  • Dry environment: Avoid vacuuming wet debris or using the robot in very humid areas.

Persistent odors after thorough cleaning may require replacement of filters and, in severe cases, the bin/cyclone assembly.
