70s vintage vinyl record cleaner, Benjamin groove sweeper for LPs

Here's a Benjamin Groove Sweeper, a 70s vintage electric cleaner / conditioner for your vinyls.

We don't know a lot about this piece, but it's easy to use (we tested it without a problem, without instructions) and it really works. You can see the difference on your records!

It's showing some wear to the housing from use, and we have no instructions for this piece, sorry.
