ciblink

Hello: I am searching for a nozzle that will work with my Simplicity Jack for my (almost) wall-to-wall wool carpet. It is a combination of short loop and non-loop (I don't know the carpet lingo, sorry.) When I purchased my vacuum 7 years ago at an authorized dealer, I was given (traded) a nozzle that was good for my carpet because it is an auto adjuster to the carpet height. (It came with a nozzle for regular, thick carpeting.) I've had it looked at and cleaned professionally, but told that there wasn't anything wrong with it. It makes an annoying clicking noise. I can't find any markings, save for Made In Germany, on the nozzle. I found a picture of my nozzle on the internet and it appears to be a TK270 by WESSEL WERK. Is this an ok nozzle for this type of carpet? My original dealer is not local to me any longer. Thank you.
