I guess if you have a firewall in your network you can block a bunch of ports and severely limit the outgoing traffic of your box or alternatively to install some privacy oriented third party ROM on your box .
I have an old Neato robot and I would love to be able to flash some custom firmware on it considering that the company went bankrupt and even when it was working their software support was pretty bad.
How is your mobile coverage, mine is pretty shitty.
