This model is exclusive to Comet. It is the same as the Dyson DC25 Animal / All Floors except that it has 2 extra tools (and is a different colour!).
A very good deal if you're after a new vacuum cleaner. It comes with a 5 year guarantee too.
There are quite a lot of reviews to read on Comet's website.
Hope you like the deal!
