Roomba is a lot like having a toddler or a puppy. You have to Roomba-proof the room before you just let it fly. Pick up cat toys, raise electrical cords off the floor, shut doors to rooms you don't want it to go into. Once that's done however, Roomba just does its own thing, scooting around, following a pattern only it knows. So far, I've "vacuumed" the living room twice with it, and the bedroom once. It hasn't gotten stuck in the corner yet, or trapped under anything, or eaten anything it wasn't supposed to. It's been perfectly behaved the whole time. It did stop and beep at me to change its
The boys were always horribly freaked out whenever the upright vac came out, but the Roomba is quiet enough and small enough that they don't pay it any attention. Both cats made a point of ignoring it from the safety of the bed while it zipped around below.
True, I've only had it for two days, but the Discovery seems to have addressed all the complaints about previous models, so cleaning power, maneuverability, and battery life has all been improved. Plus, it's just too cute! It really seems to have a cheerful personality for such a little robot, and it has picked up enough cat hair to knit a cat hair sweater for every member of my extended family. (Hmmm. Christmas present idea for next year?) I have a feeling that the Roomba and I will be playing together daily. I'll have it do a different room each day (plus the living room every other day), so that no matter where you are, you'll have that just vacuumed feeling.
