Hello,
We recommend checking if there is any hair tangled or obstructing the side brush. Please disassemble and clean it. Alternatively, you can try replacing the side brush with a new one to see if that resolves the issue.
If cleaning does not help, it is likely a hardware failure. We suggest contacting our after-sales service department for further assistance.
