I had a roomba i5 fully stop working earlier this year. It said it couldn't connect to the internet but I believe what it meant was "some aspect of the remote server has decayed to the point that it no longer works with this platform". I threw it in the trash, vowed to never let this happen again, and got a valetudo machine.
I think the lights have been off for some time already.
