I have a Miele C3 Cat&Dog vacuum cleaner. This brush must be compatible. Well, after spending about an hour playing around with it, surfing the web and making a few phone calls, WHAT I FOUND IS: Yes, it FITS. You can either put it on the black tapered end of the handle (when the stem is not attached) or on the black tapered end of the stem. There is a HUGE GAP, you have to position it EXACTLY RIGHT for it to get stuck there and then you have to ADJUST it. Kind of a pain in the you-know-what for such a high-end vacuum cleaner. Just take a look. I'll go insane if it doesn't get fixed there and the swivel actually comes loose as other reviewers have pointed out.
