It is as dumb as these things come. It has no navigation other than IR on the front to not bump into things. It doesn't connect to wifi. I'm not concerned about it sharing data because it has no way to do so.
I turn it on once or twice a week as I'm about to leave for work. When I come home my floors are in decent shape. It saves me about an hour a week on sweeping.
Minimum wage here is $12/hour so even if that's what I made, it would pay for itself in less than ten weeks.
