Also very fond of the Roborock S5, in fact I recently got a second one for the other floor - totally took it apart, cleaned it, put it back together and stuck Valetudo onto it. The first one is from 2017 and still going strong - issues so far: battery replaced (only recently), laser motor replaced, fuse replaced. Aside from the fuse it was very easy and doable for basically anyone.

I’ve had two S5s die on me recently. They kept shutting down in the middle of a clean, and from what I read, it needed a battery replacement.

Ordered one off Ali Express, and after another couple months, it also started dying. So replaced it with a newer Roborock.

Didn’t bother when the second S5 started doing the same, just got a new Roborock.

Both new ones have been going well so far, and while it does seem to be good for replacing parts (I had another lidar part fail, and the replacement was easy), I was disappointed that replacing the battery didn’t fix the shut down issues.

Shutting down in the middle of work is a common failure mode for overheating, for men and machine. Got an IR camera?
