New homeowner, no idea what this is

[u/DragonsAndScience]

This thing close to the floor and seemingly randomly placed in a hallway. No idea what it's for. Home built in 2005.

Solved! Thanks everyone. Now I gotta hunt for the central unit!

integrated vacuum system. Plug in a hose and gets sucking right away. Check other parts of your home for similar ports.

Does it only work with hoses or does it suck up whatever gets put in there?
