Oldturkey03, your "If there is uneven resistance between the wheels, hold down Roomba’s SPOT and DOCK buttons for 10 seconds to reset the robot and try again." worked a charm for a few seconds. After a short straight spell, my roomba went right under the bed (nothing on the floor) and did its circles. I have tried reboot, removed and cleaned wheels and vacuumed the roomba. Am at a loss.
