The application is corrupted beyond repair. I went to the trouble of finding 3 versions of the app - one app store and two APKs - three phones, two networks - the app never completed the "binding" (connection). The vacuum gets an IP address and can be pinged, but it will never save it. I've tried contacting support but to no avail. The application also has simple grammatical errors that did not inspire confidence. The last straw was that searching the web turned up dozens of people who had the same device issues as me, and each of them had to do a different complicated thing to sync their vacuum. Maybe I just had a bad block or they made a bad batch but after 4 hours of trying to get it to work I got it back. On the positive side, I can say that it sucks very well. , and the manual controls were responsive and would have been helpful on my replacement model.
