I got one of those. Thing's been a pain. Last time I let it run, it drove into the kitchen, did a small donut over a tiny spot immediately in front of the door, drove back out into the hallway, proudly announced that it had completed cleaning, started towards its charging station, made 2 attempts to park, missed both times, announced that its path was blocked, and just stopped. I absolutely do not trust that thing to be able to do anything unsupervised, at which point why even have a robot vacuum? I don't use it very often anymore.
