New vacuum robot (Roborock Q5 Pro+) configured, it has mapped my place, cleaned up 3 times and emptied the collected stuff into the auto-empty base station. That's truly progress! Now I can let it run unattended (for example when I am traveling) and will never get the "dustbin full" message again :) It's not the newest, shiny, top-of-the-range model. Which means it wasn't that expensive ;) 300€ that will now have to prove its worth!
@jwildeboer yeah, we also got a new robovacuum and went with Roborock Qrevo Curve which also has tanks for fresh and dirty water and washing & drying its mop, so you can service it on weekends for example, huge step forward.
