Hi there, please check whether the mop pads and mop pad holders are installed correctly. If the mop pads have been used for a long time, try replacing them with new genuine Dreame mop pads. You can also swap the left and right mop pads to check whether the issue follows a specific holder, which may indicate a problem with the magnet on the mop pad holder. If the issue persists, remove the mop pad holders, restart the robot, and then reinstall them. Should the problem continue, please contact support.na@dreame.tech for further assistance.
