Dysons colour descriptions are a mystery to everyone.
That should have what we call
a standard silver cleaner head on there, but Dyson being Dyson, show grey, dark steel, light steel and steel for that model. Also shades of silver can vary a tad so the right colour supplied today may differ to the one on your machine a tad.
We are in the process of building a way better parts shop than what we have now, and I had this very problem last week, of how to categorise exact shades of cleaner heads. In fact, I ordered every new one available in just to compare part numbers and stated shades to common sense descriptions. I haven't done it yet lets say..........
If you want a new cleaner head, I *know* exactly which shade you need when I look at them, but I dont have it to hand right now as I am not in the shop.
PS, I didn't know that lavender chassis was for you a few days ago. Good job I picked the best one we had of three. Next time you call, tell Claire who you are as we'll always try to be keener on price for active forum participants where we can. Especially if sending a few items out together.
