I have a Roomba 960 I purchased in 2016. Every day at 10:00 it is programmed to automatically start and vacuum the house.
I've replaced the battery once, about a year ago. And I've replaced the spinning brush, rollers, and the filter many times.
Only problem I have is the two drive wheels are worn smooth, so it no longer has much traction. It struggles to drive over some of the flooring transition pieces between different rooms. I don't need the whole wheel assemblies, I just need the "tires" with fresh rubber threads.
Would be interesting to know how many kilometers it has driven over the last 10 years. #Roomba
