Mustiness can travel from pads, roller cavities, dirty-water tanks or a neglected tray. Identify the damp component instead of treating the floor with more fragrance.

Start with these checks
- Remove and inspect the washable mop components permitted by the manual.
- Empty wastewater and clean the accessible tray.
- Dry the appropriate parts fully and run a fresh approved-water routine.
What this looks like at home
If the smell starts as soon as the mop touches the floor, the pad or roller deserves attention before the vacuum filter.
Keep clean water, dirty water and dry dust separate
| Check | What matters |
|---|---|
| Clean-water side | Use the permitted water and solution method. |
| Dirty-water side | Empty and clean the removable tank as directed. |
| Pads, roller and tray | Inspect, clean and dry only as the manual allows. |
A mistake to avoid
Do not add bleach, essential oils or mixed detergents to the robot tank.
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
Check whether the smell begins at the dock, appears only when mopping starts or remains on the pad afterwards. Cleaning the confirmed damp source is more useful than changing unrelated dry-vacuum components.
