Buying this was so confusing because there are 5 versions of Dyson V6: Absolute (pink), Clean (red), Fluffy (blue), Animal (purple) and Standard (White). I bought the V6 Absolute but I want to share my experience here to help you decide the right version for you.
The difference among the Dyson v6 versions:
Standard - has a 20w motorhead attachment, this is the weakest of the series and a crevice tool
Animal - same motorhead attachment as the standard. In addition it has a mini motorhead for pets
Fluffy - has all the above and one additional soft brush attachment specifically designed for bare / hardwood floors
Clean - has all the above but a more powerful 35w direct-drive cleaner head - which replaces the standard 20w motorhead.
Absolute - has the mini pet tool as above, a more powerful 50w direct-drive than the Cleaner, and oddly, a very plain / simple attachment with silicon wipes for hardwood floors instead of soft brush attachment. In addition it has a Hepa filter at the motor exhaust - this also makes it a little heavier. All this will make the battery work a lot harder than the lower end versions.

Thanks OP was just to about to buy at a higher price

Also x10 Nectar points as well, nice added bonus!

Is the V6 animal the same base machine only with an additional head?
trying to work out if its worth the extra but looks like all you get is a different coloured 'hose' and one additional head?

Bought one when they were £149.99 absolute bargain and a god send for hoovering up after the dog everyday! think we've used our main Dyson once since buying this.

Brill, just ordered. Thanks op

so the main attachment (which is the same) isn't as powerful on the standard V6 because the motor is different?

I though that the only difference is that you get Mini Motorised Tool with Animal model ?

That's what I'm trying to figure out. £30 extra for the mini tool is definitely not worth it (I find the non power stair tool thing better anyway) but if the motor is different then the animal may be the better deal here.. perhaps even the fluffy as the head seems to go for about £50 on ebay..
