question for those of you with a roomba:
how durable are they?
seeing as how they move around on a floor, lets say i have one scheduled to vacuum the room while i sleep. lets also say that i wake up in the middle of the night, half asleep, and don't bother to look where it is. finally, lets say i step on it. is it broken now? or is it built tough enough to probably survive?
ps: they have one on sale now at shopping.yahoo.com (sellout.woot.com) that i just bought
