Roomba Max 705 - Anyone else gotten it to work?

Wife gave me a heads up that she expects we'll get a Roomba from her parents for Christmas - most likely a Roomba Max 505 or 705 (or the Costco variations on those).

Looking at the Roomba Integrations page for HA, I saw this line:

It currently does NOT work with the newer x05 Wi-Fi models, such as Roomba 105, 405, and 505

I was wondering if anyone had tinkered with any of those candidate models and had any success getting them to work with HA?
