A:Answer Hi,
Please note that Deebot T8AIVI comes with a rolling main brush, which helps clean debris and hair. If there is a lot of hair, it may cause the brushes to wind up. It is recommended to clean the brushes regularly to keep Deebot in good condition. Should you need any assistance please reach out to our Customer Service Support Center and we’ll be happy to help out with any questions you may have.
Best,
Ecovacs Customer Care
