Hello,
We apologize for the inconvenience caused.

It is recommended that you re-map the whole area. After the device automatically recognizes most of the carpets, you can then manually add the carpet areas that were not identified. This method can reduce the need for manual carpet additions.

If the issue remains unresolved after completing the above steps, please contact support.na@dreame.tech for further investigation and assistance.

Kindly please provide a screenshot of the map and the error message. Thanks.
