Trying to identify Rug Cleaner Attatchment

[kwhitcomb7159]

Hello;

I have been carrying this little attatchment around for over a year trying to identify what it goes to.
I am adding pictures in hopes someone can help.

Attachment?

That would be for a 2 brush floor polisher along with softer brushes and shampoo tank to convert to carpet cleaning.Possibly Shetland or Sunbeam.
