Robot Vac leaving black marks

Is anyone else having issues with their robot vac leaving black scuff marks on carpet when it’s trying to switch levels from one carpet to another or gets hung up on an item like the base of a cat tree or a music stand?

I seem to be cleaning black marks off my carpet daily as these issues occur and they aren’t coming up very well. I love the vac however don’t appreciate black spots/marks or lines on my carpet.
