Why can't DEEBOT recognize carpet completely or recognize a carpet as floor sometimes?

Currently, some special materials and specifications of carpets may disturb the robot's recognition. Such as:

• Carpets with extremely hardness (similar to wooden floor hardness)
• Carpets with hair length less than 2mm
• PVC or other special materials

Additionally, you can open the app, tap Map Management-Map Edit-Add Carpet to make relevant settings.
