Robot vacuum wheels have permanently stained my hardwood floors

I never thought to check until I stumbled upon this thread. Looks like mine does it too. I haven’t tried cleaning yet but here’s my MAC
7C78B20A0BA0

Can you provide the MAC address of your vacuum? Thanks

Just saw this thread and checked mine. I have dark hardwood floors, so haven’t noticed anything while the vacuum is undocked, but I just looked and there are some small smudges where the tires sit, no square tire marks. However, I can feel the residue when I rub the floor, and if I rub it hard enough with my finger or scrape it with my finger nail, it comes off.

I’ve had the vacuum in the same spot since February.
