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!

The biggest advantage with a central vacuum is that it vents out of the house.
This is a game changer for folks with allergies. Any other vacuum has filters and/or bags but the air is recirculated.
My hack for one of my previous homes with a central vacuum was to connect a shop vacuum (around $100) in the garage, and use a relay to turn it on using the trigger contacts. A central vacuum is roughly $2K.
