High Internal Humidity error
This alert appears when moisture builds up inside Matic, most commonly after a mopping session or in warm weather due to condensation. It usually clears quickly once you air it out.
Steps to resolve
- Open Matic's lid
- Remove the bag
- Wipe away any visible water in the bin
- Leave the lid open for 10 minutes
- Reinsert the bag and close Matic's lid

Note: While docked, Matic periodically runs its fan at higher speed to purge humidity from the system — this is normal and doesn't require any action.
