I just got my Powerbot R7040 back from being serviced because it wouldn't resume cleaning after recharge. Now that that's solved, I am having the issue where it wont produce a map of where it has cleaned after it is done. In the 8 days it has been cleaning the house, it has only produced five maps. There have been no errors, it has not been messed with during cleaning (like picked up), and it has successfully returned to its docking station each time. What is going on?
