I just bought a refurbished DC27. The connection between the hose and the handle doesn't seem tight to me, i.e. when I use the wand to clean upholstery. Unlike when I put the attachment on the end of the wand, or when I put the handle in to use vacuum upright, I don't hear a click, and the handle will actually slip down a bit by itself when I use the wand. I called Dyson's, and they said this was normal, but I'm skeptical. Also, while there's some suction, it doesn't feel like much when I put my hand over the attachment. I'd appreciate any suggestions!
