Botvac serial interface edge connector on system board.

Why is it important to have our Botvac connected with WiFi ???
I bought the D75 because it's less expansive.
I think a remote controle IR miss to my neato. A simple remote controle with 2 buttons. Work, and Home.
I could hidden my D75 under my fourniture (meuble en français)
Sorry for my bad english.
