Start with these checks
- Stop collecting damp debris and remove the dock bag as directed.
- Inspect accessible dry-debris passages and the robot bin for contamination.
- Clean permitted parts, let them dry fully and fit a suitable fresh bag.
What this looks like at home
Food crumbs left damp inside a bag can smell well before the bag reaches its volume limit.
Dust automation still needs an open path
| Check | What matters |
|---|---|
| Robot bin | Check the outlet and closure. |
| Station path | Inspect permitted openings for dry blockages. |
| Bag and timing | Confirm correct seating and model-specific emptying rules. |
A mistake to avoid
Do not add essential oils or powders to the station unless the manufacturer permits them.
Buy a part only after identifying the cause
Check the exact model and part reference before buying. If cleaning resolves the problem, a replacement may be unnecessary.

What the result tells you
If a fresh correct bag and clean permitted passages remove the smell, identify how damp debris entered the system before resuming the old routine. Otherwise, the next bag may develop the same odour quickly.
