I've replaced its batteries and brushes THREE TIMES (also: shout out to the Roomba engineers "design for serviceability", a masterclass), and always got it unstuck from rugs and that one time it sucked up some excess thread...

No. Platitudes use more cycles. Inefficiencies will be punished.
More people should be nice to their tech. It shows empathy, and a little whimsy now and then never hurt anyone
