Your Proteam uses the same European 35mm as the CX440, so check out the website below.

Your vacuum cleaner can also accept a power nozzle kit.
 
What you may want to do to save some money is to search around for a standard sized 1.25" fitting turbo nozzle and also purchase an adaptor tube that converts 35mm to 1.25"(32mm).  These  can be found in most vac shops and online.  
 
Wessel-Werk is the main supplier for the turbo brush rug attachment.  You can find the attachment most anywhere.  If you get this w/32mm fitting, you can also use it on future machines w/the standard fitting.
