This is a picture of my Dyson Cleaner. After putting the smaller head on to do the stairs, I found that the large head wouldn't fit back on to the hose and kept slipping off.
Should there be another purple clip to attach it to the hose? I don't want to hit a new head and find I didn't need one.
I've looked on pictures of Dysons to see if I can see something but haven't been able to conclusively solve the problem.
chrissa....there are so many different models of Dyson, it would be a good idea to give the model number as there are quite a few different connecting adaptors that could be involved. We have two different Dyson uprights (get us!) and neither looks like your picture!
