We don't all live in leafy Surrey lol
Thanks! That explains the comment in that Amazon question that you can get a universal adaptor if needed. A quick Google revealed this item available on Amazon might serve as an adaptor. It's about a tenner though.
V8 and V10 attachments are different to the rest - the release button is on the attachment itself to allow 1 handed removal. I doubt this will fit newer handhelds
My dyson came with this attachment, can confirm it’s awesome for pet hair
As to what models this works with, I think the only issue is the old handhelds with lower suction won't work very well, because the tool isn't an electrically powered tool but instead powered by suction. I would imagine that the connection itself is pretty standard. Therefore modern handhelds should work. I didn't see anything that specifically said it wouldn't work on a modern handheld. I haven't combed through all the reviews to verify this however... EDIT - there is actually a question about this on amazon link
