Dear Customer,
These marks are most likely caused by the robot vacuum wheels rubbing against the floor, which is a common minor issue during normal use. You can first gently wipe the robot wheels to remove any attached dust or hair; this will help restore a clean appearance and keep them rolling smoothly. If there are still any abnormalities after cleaning, please let us know at any time, and we will further check for you and provide appropriate solutions. We look forward to your feedback and wish you a pleasant experience using it.
Best regards,
Lin

Dear Customer,
Currently, the robot will perform edge scanning and mapping each time. You can check the current map anytime in the app. The system will automatically remap the next time you use it, so the robot can immediately recognize its surroundings after the environment changes. If you want more flexible cleaning, you can also switch to random mode, allowing the robot to freely cover the room. We recommend letting the robot complete a mapping once after changing rooms before turning on random mode, as this will improve cleaning results. We look forward to your experience and welcome your feedback at any time.
Best regards,
Lin
