I want to give it 5 stars so bad but it does have its limitations. The unit comes with this strip that you cut to keep it from crossing or going into an area. Well the vacuum will climb over and still go thru that area. My biggest pet peeve is I wanted to connect to my google home and it’s almost 2 months and can’t. I have a dog pug that sheds lots of hair. My wife was telling me that before the Shark Ion Vacuum the lint filter on our dryer would fill-up with dog hair on every use. Now it’s almost no hair in the dryer filter, that incredible!!! Over all I love my Shark Ion IQ Robot it connected to my WiFi the first try and the app is easy to use. Oh and before I forget the self empty feature is life changing. The directions say empty once a month but I empty it once a week and always surprised of what it’s picked up. Over all it deserves 5 stars if Shark helps me connect to my google home then I will be one HAPPY Customer. Can you say satisfied...
