iRobot Roomba j7+
My robot vacuumed really well at the beginning. Now, after 2 years, it misses entire areas in corners or along the walls. I have already started a new mapping - but the suction result is still not the same as at the beginning. Should I try uninstalling the app or is there such a thing as resetting to factory settings?
