We have a white German shepherd and if you know you know . Our house is full of white fur that's gets everywhere and is never ending. We had the Roomba I3 and decided to upgrade to the J9+ vacuum. WORTH IT !!!!! We have it run and now I feel like we have our house back . The self empty features is amazing !!! Beforehand I would have to empty it out several time on a clean because of all the fur. Now when it gets full it goes to the base and self empty and continues with the clean . I love my roomba and it makes me feel so much better coming home to a clean house and not having to worry to vacuum everyday .
