Sweet, so I followed the article there: https://www.snakeoil-os.net/news/home-automation/how-to-control-your-xiaomi-robot-vacuum-with-google-home?page=2
Basically, it involves running "Home Assistant" somewhere on your network. I run it inside Docker on a DS416play Synology router but you could run it on a RaspberryPi or windows computer or whatever else.
Once you have that up and running, you use IFTTT (If This Then That) to hook up Google Assistant to a WebHook which will make a direct API call into Home Assistant. (Needs Port Forwarding for port 8123). Once Home Assistant is configured properly, it'll know how to talk to the vacuum upon receiving that API call.
Have a look at the link and see if it makes sense and I can help if you are having trouble.
