I can see you guys have no faith in me, of course I checked with dyson because I found that adapter on many sites including theirs, so I called dysen and asked if I could use it with my other attachments. They said that the adapter only works with their attachments, "Some of their attachments need an adapter". I asked the salesman to check on this, because it didn't make sense to me, he said he checked and "No the adapter would not work on other attachments". So, I'm assuming some of their attachments go to any of their machines and you need this attachment to hook this up to the animal.
The kit you bought Bonny has what looks like an adapter in it, and I thought you could see for yourself if you can attach that to regular attachments. See picture to see what I mean. In the meantime, I bought this set
Dyson Home Cleaning Kit : Target I can see you are no Suzy Homemaker, I would have ripped that box apart, and tried out the new attachments. Lol, I seriously can't wait for mine. I just love buying something that actually works like they say it will.
