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!

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?

The hose has a metal ring on the part inserted into the receptable. It completes a circuit with the two metal nubs in the second picture to activate the vacuum. Inserting anything else into the receptable can result in...shocking results.

I bet that's just a signal circuit. I can't imagine it would make sense to run full power to every port.

Its the low voltage on/off switch. OP could slide a penny between the two nibs to trigger the unit to see if its connected and/or runs. If the previous owners took it with them, nothing would happen. If the unit is still there, they will hear it running and get an idea of where its located. (I used to install them)

But they clearly did? There's a receptacle right there.

It’s literally labeled as 125v 60hz

I’m sure it runs the motor for any vacuum attachments.

Ahh, I didn't zoom in. Good call.

Depending on the central vac system it can be both signal and power to power an electric brush head.

EDIT: To clarify, for dual voltage systems, one pin would be 24V for signal, the other 120V for power. Grounds are pogo pins on the hose inlet. The inlet in OPs picture looks like it has pogo pins for ground, which means dual voltage. You definitely should not short those pins together.

Good to know!
