I’m looking for a vacuum robot preferably under 500€ and with a cleaning station. My main concern is that most robot vacuum providers seem to need to be connected to the internet. Are there any providers that either don’t need that, where I can block the internet connection or any other way not getting a spy in my home? I’m fine with it if some work is needed
The easiest way is to put your IoT devices on the guest network and block internet access to the network, but you could do firewall rules if your router allows that.
Or, get a home lab router instead of consumer grade. I went with MikroTik, and it’s a great bang for your buck. It’s not too dissimilar from Cisco in the cli, but the GUI is nice too.
