I got a DC44 traded in today, lovely machine! Just needed the terminals for the wand cleaning and a good charge

I plan to keep it now
I just
need want a mini motorised head for it, I can't find any cheap ones on eBay besides some aftermarket ones and expensive genuine ones. I did, however find some nice looking cheap V6 ones, I'm 99% certain they don't fit but is there any modification I can do or are they a different size altogether for the slots?
There was a thread like this that I can't seem to find, but I remember reading something like a Dc35 motorised head won't fit a DC44 or something
I would get a non genuine one if the price is good but what's the difference between that and a genuine one? They can't be clones can they? lol
If the bristles are stiffer or if they clean just as well or better than it's worth goinf for the non gen I suppose... not very experienced in any cordless after the DC35.
I had a non genuine large floor motorhead for a DC34 and it was alright, the carbon fibre felt fake and there were wheels instead of a ball, so God knows what the non genuine mini motorheads could be lacking from the genuine ones
Thanks
