I replaced a 880 roomba with the J9+ vacumn and the difference is great! I like that it maps the whole house and then I can tell it to clean a room and it takes off and cleans that room then goes back to dock itself and emptys itself .

This is not worth the extra money you pay for it. Not only did it run over dog poop once it done it twice and drug it through the house. I will say I did call them and they are sending me a new one but save your money and buy a different roomba.

The J7 is better than I expected. It picks up more dirt and dust off the flower than I anticipated. The vacuum is not done mapping the house so it still wanders and bumps around. What has been mapped by the J7 it moves thoroughly and quickly.

I love it!!! I have 3 short haired dogs and a white tile floor. I wss goi g crazy with all the little black hairs. Even my husband who was totally against it notices how great it working and said wow that thing is great!!!

This little robot helps me keep my hardwood floors clean. It does a decent job of getting dog hair and the catch bin holds more than you expect. I love the app and the ability to set where and when my helper cleans. Great purchase!

We have a golden retriever and I was at my wits end with all the shedding! If you have a golden, you know exactly what I'm talking about. I researched models and the j9 was exactly what we needed. A real game changer! Love LOVE!

Works very well. I bought this model specifically so I could operate it on my Orbi wifi mesh system. I'd originally purchased, and had to return, an I4+ that could only operate on 5GHz. This operates on both 2.4GHz and 5.0GHz.

the vacumb does an excelent job cleaning, inc. corners.I must pick up only my light scatter rugs.The vacumb has not bothered any cords or small objects.I love it.

I had to return, because I have dogs and I ended up having to empty the Roomba every 2 minutes, because it wasn't a self emptying unit. I had trouble getting it to find the kitchen also.

Bought the Robot Vacuum and 9 days later I glance online and see this product is selling for $150.00 less everywhere now. My fault I guess but I got stuck.
