Charging Stuck

Hello Dreame Support Team,
I am experiencing an issue with my Dreame L40s Pro Ultra. During charging, the robot occasionally stops charging and remains stuck at a specific battery percentage (e.g., 40–70%). This issue occurs intermittently and prevents the battery from reaching full charge reliably.
I have tried ensuring proper docking alignment and cleaning the charging contacts, but the problem persists. Restarting it once fix the issue but not anymore, Could you please advise on troubleshooting steps or potential solutions?


Thank you for your assistance.

Hello,

Thank you for your detailed description of the device's condition. Regarding the issue of the L40s Pro Ultra getting stuck at a certain battery percentage during charging and unable to continue charging, this is usually related to abnormal charging contact, system recognition, or battery status. We suggest you troubleshoot using the following steps:

1. Check the charging contact between the base station and the robot.

Please clean the metal contacts on the bottom of the robot and the base station again, ensuring there is no dust, water stains, or dirt affecting conductivity.

When placing the robot in the base station, confirm it is backed up in place, without wobbling, and properly aligned.

2. Restart the base station and robot.

Power off the base station for 1 minute and then power it back on.

Press and hold the robot's power button to restart the device and allow the system to reinitialize.

(You mentioned a brief recovery before restarting, but this is currently ineffective. We still recommend performing this step again to rule out temporary system abnormalities.)

3. Check environmental factors.

Avoid movement, collisions, or human interruption during robot charging.

If you have tried all the above troubleshooting methods, there may be an internal hardware fault in the device. You can contact our after-sales team for further assistance.
