That's really cool about the hair stuff. I never would have thought to use it that way, but it's neat that it gave you a usable product. As for the robots... I'm just not sure. I've never been a fan of a lot of the connected devices anyway. Which is funny because I am tech guy, but some things I just like old school. A robot can vacuum for me anytime. I don't think my wife would ever allow it. She wouldn't be able to look at the thing.
