Bests & Worsts Reviews from Amazon

This device (we have the 690 model) has proven to be much better than I expected. I have pets with long hair and while you have to run it a lot to get all the hair, there is no way we would ever have the patience to vacuum a rug for as long as the Roomba will do it. You can vacuum and then run this and have a lot more hair picked up. I put it in our bedroom, close the door and let it run until it needs recharging (about an hour). It's also fun to watch it learn if you happen to be in the room with it. It works well on our short shag and gets up under things to vacuum the hard to reach places. The only down side is that there are no attachments so you can't use it to vacuum pet hair off of furniture. Another possible down side is that anything spilled or if you have a pet that is not quite housebroken - as smart as the Roomba is it cannot smell or see - it will spread anything just like you stepping in it and walking around the house without knowing.
