I would like a robot vacuum cleaner, but my house it a bit tricky because there are steps up and down into the kitchen and utility etc. I think if I just get one that I can plug in to charge, rather than one that self docks, I could just set it to clean one area at a time. Would that work? I know it's not as efficient, but as long as I can just move it from one area to the next I'll be happy.
