Bah, my Roomba has started to do the circle dance (going round and round in very tight circles). While it's somewhat cute (as with anything involving a Roomba), it also likely means the tachos in the wheels are gunked up.

Time to dig out the support number for it. Apparently you can get a dongle from iRobot that reprograms the Roomba and somehow fixes this in software (probably by ignoring the tachos, but a software fix for a hardware problem is still impressive).
