Question about Dyson Soft Roller Cleaner Head

Unfortunately, I can't give you a useful answer.
It just worked for me, and I was very happy with it. My basic device was more from the cheap Dyson series, but the Fluffy part still worked.

Yes, it fits Slim. A bit strange because of the weight, the other gland was lighter and therefore glided better.
But I bought it because the other gland didn't suck up the breadcrumbs, but spiked them to the back. This gland sucks up everything, really great! :)
