As useful a smart device are, it's very annoying that the company behind it are always either: 1) a scumbag that will collect data and will lockdown the device if people doesn't use it their way; 2)incompetent idiots that can't make a good software to save their life. So by using these device you basically have to pick the thing that you're willing to lose.
It's really too bad because robovac save me a lot of time and mental exhaustion.
