I own a Kirby Ultimate G Diamond Edition, and I too am so very sorry I answered the door when the Kirby rep came.
I paid $1200.00 for this vacuum and dread using it. It is soooo heavy, the hose falls apart when using the attachments, and on some of my really expensive rugs it has pulled out little fibers. I have set the height so many times trying to get it to actually clean my rugs to no avail except to do damage. The handle has actually fallen off during vacuuming!
The other drawback is that most of my house is pine floors, then I have area rugs in all rooms, so I have to first use the hard floor attachement and then go all the way back through the house with the main head attached to clean the rugs. Way to time consuming for me. This vacuum is just a real pain to me, and I'm just sick that I spent so much money!
