This doesn't seem normal. Please try to reboot your device, see if that helps: press and hold the power button to turn on or off the robot vacuum.

Is this something that can be reproduced consistently? Can you share some screenshots of the cleaning report from when the problem occurred?

Do you have a report photo taken after the cleaning task finished (manually ended)?

Can you confirm if this is an issue that can be reproduced consistently? For example, you can try to do some tests yourself -- place something like a box in the middle of the room and then send the robot in to clean. Then watch what it does: does it just go around the box and clean normally, or does it hit the box and immediately give an error and go back to the dock?
