Then just buy a Roborock and get on with your life... why sit there boiling about anything?Right now I'd setting for something that doesn't boil my **** when it's running!
Vacuum robots without intelligent mapping & navigation are pointless, it would drive me up the wall as well.
Yup, this. Buying a crappy Robovac without intelligent features is a false economy.
Honestly, the minimum I would buy is a Roborock Mi Robot with Lidar (the original edition) as not only are they so well made and well featured but, very importantly, spare parts are cheap and easily available.
