Dyson motorheads - what's the difference?

[unconscious]

Hi guys,

I've recently been on a research quest that has left me full of questions and little answers.

So I have a V7. I'm considering getting extra motorheads for it (e.g. the small one or the soft roller). I realise that whatever accessory I'm getting it'll need to be the one with the red Quick Release button thingy. I found a small motorhead on eBay that I know the seller has from their V8. At this moment I'm assuming it should change much whether it's a V7 or a V8 since they're practically the same machines (right? right???).

But then I go on Dyson's website and I see that they sell them as two different items - a V7 motorhead and a V8/V10 motorhead. On top of that, they also differ in price by a few pounds (the latter being 4 quid cheaper).

Why? Is there a difference in voltage? Is the electric fitting ever so slightly different? I emailed Dyson (i procrastinate a lot when I have assignments due okay) and they gave me a very vague response of 'they're just dedicated for different machines'.

Has anyone ever tried interchanging their motorised tools between a V7, V8 and a V10? How did it go? Did anything explode? Did James just turn up out of the blue to shout at you?

I could be wrong

I think the tool lock system is "reversed" with the new red button with the V7 on down the male end was on the machine and the female end (notch) was on the wand or tools. It looks like on the V8 the notch is in the machine and the male end is on the tools. Looking at a V8 fluffy head it definitely appears that the locking system has changed going from a rectangular notch or a channel around the tool to a circular shaped notch. So....no the tools would not be cross compatible
