I'm surprised at the good reviews of the Roomba here. I got one a few years, and found it basically worthless. Everyday I'd come home and find the inventive way my Roomba had discovered to fail. Somedays it would get stuck on a chair leg, other times it would get trapped behind doors, or I'd just discover it dead somewhere without a clear explanation. I had been hoping the Roomba would make my apartment and sweep it intelligently, but as near as I could tell, the Roomba just moved at random. I also found the power of the Roomba was weak. Inspecting my floor afterwards, I'd frequently find the same kind of lint, or detritus that made me want a Roomba in the first place. Maybe I was just unlucky, or had a bad living space for a Roomba, but in my experience they aren't worth it at all.
