The Roomba j9+ is a self emptying robot vacuum. Honestly, this is our favorite feature. With a dog, it is great to not have to empty the vacuum every day. On the down side, you do have to buy bags for it, but they seem to hold a good amount. Pros Self emptying Can set zones in the house Can set a schedule Looks nice Cons Rather loud compared to competitors Extremely loud when emptying Have to buy bags
