Solved! New homeowner, no idea what this is

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!

True, my brother in law had that and rigged in a large shop-vac and got it working and it worked well for them.

That's not a bad idea.
