iRobot Combo 2 Essential Robot Vacuum Black

So, it works. It runs every other day and the house looks pretty clean all the time, except for one area rug that clings to dog fur like iron filings to an electromagnetic crane—even our Dyson can never get that thing pristine. But, holy _crap_ is it painful to watch. This thing manages to trap itself in open areas constantly, where it'll bump into an obstacle, back up, turn around and go back a foot or two, turn back around, and run into the same spot on the same obstacle. It's even worse if there are two obstacles near each other. I would almost think that its map is strongly indicating there is supposed to be reachable area just around that obstacle, but the obstacle isn't on the map (a moved dog bed, a chair slightly out of place). Except, the maps it generates are incomprehensible. It doesn't even show its home on the maps, and the fact it frequently takes 30 minutes to find its home confirms it has no idea where it is or what the house looks like. It's painful to watch in the same way that it's painful to watch someone hunt-and-peck at 2 words per minute and repeatedly make typos. What's genuinely irritating, though, is knowing that this thing is wasting time and battery going over areas it's already visited, trapping itself in corners, and convincing itself that it's trapped in an imaginary corner. Oh, and that it'll report it cleaned 600sqft when I know for a fact that it got stuck in a closet for 45 minutes. Update: It got so lost trying to find its home that it ran out of battery and died (about six feet from home, btw, where it had been for twenty minutes). And I do mean it _died_. I put it on the charger and it hasn't charged after two days. I've tried holding the button to reboot it per the instructions, reseating the charger contacts, even opened the battery compartment to check the connection there. It's dead. Update 2: after sitting on the charger for four more days, it actually woke back up. I'd already ordered a replacement from Shark by then, though.
