My d10s is not working

I had bought this vaccuum around an year ago, and it worked perfectly fine. But recently we had shifted. After I set up the dock, the robot wouldn't connect and showed offline. I removed it from list of devices in hopes of resetting but it doesn't turn on so I can't connect to it now. Please help!

Hi, Please send us a DM with a few pictures of the charging contact point of the robot and station. It can be that the contact is not established properly due to damage or carbon layer formation

My charging station is not getting on
