To me this new v15 isn't woth all the hype. To mean its basicall a v11 with a fancy screan. Those new cleaner heads can be probably purchassed separately for older models. I'm personally gonna look into getting that hair screw tool, which is an updated mini motorized brush, for my outsize unit. What I personally like about this new model is that sit uses the same remveable battery that the v11 series does, which means the floor doc will also be compatable. What I don't understand is why Dyson skipped v12 and wen't to v15. What I'm also not a fan of is that classic dyson yellowish ornage color. to me the machine should just be chrone like the rest of the cordless range. On top of that, the iron wand doesn't seem to match it really well.
