An expensive piece of trash! I've tried everything to connect this thing and never made it pass the set up. It says its connected then tries to find robot, never finds it or make it pass that step. I made sure my network was on 2.4ghz, and was on the same network as my device. Guess if you have an Android device u can't use i3 model. You want make it pass set up, if so your very lucky. Sticking to my Dyson. At least it does what its supposed to and worth the expensive price. Returning this mess
