Your original Dyson hose with 3" tape holes will work better than this copy. Compared to the original hose with holes covered in tape, my vacuum has actually lost so much suction power through this piece of debris that I can't even use the rotating-head hose nozzle I use to clean my machine of dog hair. It's so bad as soon as I put the suction cup on the seat it actually stops spinning. This thing leaks so much air it's pointless. This only works if you want the part to use the vacuum just as a vacuum. If you want to use attachments, you have to expect them to lose more than half of their suction power. Don't buy this junk. The positive reviews here can't be real. It's literally that bad.
