I bought this attachment a short while ago, not really expecting a miraculous new discovery, but hey, its great. Ive had my Dyson animal for over two years now and I love it, but Ive always had a problem with dog hairs, they get everywhere, especially when you have wooden floors, they blow in, around and under everything, before the only solution was to move heavy furniture each and every time I vacummed, there wasnt a tool supplied with the Dyson that could reach all the way under sofas etc,Not Dysons fault, its not them with the huge ,constant shedding dog, but this gadget does the job with no trouble, It can be used as a rigid tool and it has a detachable brush, but it really comes into its own when you extend it and discover the flexible plastic hose, it can reach anywhere! I was even vacumming inside the lampshades, behind the radiators, nooks and crannys I could never get at before. If youve got a dog or places you cant get to, then get this, Its great
