For years I've wanted a robot vacuum cleaner with home mapping (to optimize routes, limit sections even by day, etc.), but they all ask you to connect to the Internet in order to use them... It is madness.
Map of your house, habits/presence and so on, I don't want to give any ideas. So I prefer a manual vacuum cleaner as one finish faster and better, at time one do a bit of exercise also.
The only way I could think on buying one of such things is to be able to use all such mapping functions without the device being connected to the internet, and also that nothing could be connected to the device remotely if I don't give permission at that moment (Even to program it I'd prefer to connect it via USB to whatever, with the requirement that the app working as UI cannot connect to the internet, of course).
I don't like this trend of recent years with devices on general. Looks like "smart" is an euphemism for "spy", spy-tv, spy-phone, spy-home, and so on. The key here is, internet connected.
