We used to have another famous robot vacuum brand which we hated and then my husband got me a Shark IQ and oh my God did I love that thing so when I learned about the AI I thought just when you think it can't get any better Shark did it! The only complaints I have is that the app doesn't seem to work too well and that it doesn't have a power switch on the robot like the IQ did. I babysit a lot and have two small children of my own so it would be great if I could turn it off to stop them from messing with it all the time!!
