After last software looks like a complete idiot. 6 monts ago i would've recomend it; now if you have strong nerves and too much money, well...buy this motorized lemon. It got lost in a 12 square meters bedroom, crashed into the doking from which just left and told me it can't find the docking. If it goes under firnuture, it can't find the way out from under a chair. Almost ran out of battery while crushing in the chair. LE: erased maps, cleaned sensors, still tries to climb the docking.
