Why would they do that?
Airbnb should invest in Shift, continue to encourage exorbitant cleaning fees, and subsidize discounts for hosts so that they're incentivized to fire their current housekeeping providers and switch to Shift.
Among other issues, it likely causes knock-on problems for tomorrow’s reservations.
So either Bot Company damaged property and is trying to pretend they didn't. Or they are incompetent and failed to document the state of the property or handle the owners complaints appropriately.
Given that their training robots and would therefore be collecting as much data as possible, including camera data, I'm leaning towards malice instead of ignorance.
Not every airbnb host has a professional cleaning staff, and some of those who do may sometimes wish to check the status of their property. I don't find anything strange, let alone "bizarre".
