Vacuum roamed around unprompted

Today my X40 Ultra left the base drove to our couch, bumped into it, said something like 'test completed' then drove back to the base and docked.  This happened at almost exactly noon my time. Has anyone experienced anything like this?

No but it sounds funny. Took me awhile to get used to mine. It felt like there was a stranger in the house. Now I’m used to it. Good luck.
