Connecting to the vacuum using this app was a nightmare. In the directions, it doesn't say that when you get to the screen where are you select the vacuum that you want to connect to, you have to exit out of the app, open your phone's Wi-Fi settings, disconnect from your Wi-Fi, find the vacuum's Wi-Fi, connect to it, go back to the app, now you can select the vacuum, then your phone will connect to the vacuum. Constantly having to force stop this app and reopen because it can't find vacuum.
