Horrible coverage

Why is the cleaning pattern so bad on my robot these days it’s been going on for about two weeks. I’ve tried re-mapping the house. I’ve tried to reset the robot. Nothing has worked so far. It worked before. I don’t know why it’s behaving so odd.

If it were me. I would place the robot in a room , close the door, and pick up shoes , cords , basically any that would prevent the bot from cleaning 90 percent of the room. Delete you map, do a fresh scan, then vacuum the room. If you don’t get full cleaning coverage then reach out to support for help.

My L40 squeaks constantly? What should I do?
