It was great at first. Now I can't get it to connect to the internet even though I'm using the same router and modem. I try uninstalling everything and then when it goes to the prompt of use prosenic Wi-Fi that will not connect. I also noticed that the vacuum when I was using the app I set it to not automatically does collect and it did every single time. I have cleaned the inside and the outside of the vacuum the sensors as well and it badly bumps into chair legs. Please help
