Afterward, with roomba upside down, (to reset the sensors) take the brushes out, hold down the wheels and cover the sensors (not completely) and turn roomba on,
I really don't think that that will reset the sensors, but if you want to, you could. It might make you feel better. If you do decide to do it, make sure that you hold the wheels down with by the edge (not the main part of the wheel that turns). That way, if the Roomba decides to run it's wheels, nobody will get hurt.
I still don't think that it will help, though.
Anyone tried it? Did it actually do anything?
