I designed this for my Orfeld cordless stick vacuum (found on Amazon), however I'm willing to guess it will also fit other cheap-from-China stick vacuums, probably not name brand ones though. It's designed so the 2 tool tips it comes with can stay on the vacuum itself, so as you clean the house your attachments come with you instead of being confined to the charging base. The design clips right onto the tube, if you find it too loose you can scale it down a tiny bit or put a dab of glue on it. The tools friction fit right in the holes.
