iRobot or Roborock

I am about to buy a Rovorock S6 Pure or an iRobot Roomba 976 but want it to be fully integratable into HA. However I don´t want them to connect via some cloud service but only locally.
Is this possible for these products?

Not for Roomba as far as I know.

Okay, thanks.
I think I will go for a Roborock
