• Robot not starting/charging: Ensure the robot is properly docked on the charging station and the power cable is securely connected. Check for any obstructions preventing proper contact.
• Poor cleaning performance: Clean the main brush, side brushes, and filters. Ensure the dustbin is not full. Check if the mop pads are clean and properly attached.
