Rich remember the two greenhorns they pulled out when we were extracting those rugs down in Cornwall on the course? I didn't like the greenhorn when I used it (either model). Two problems, firstly the glide on it is pants, it doesn't, "glide" !! I think it was more like normal plastic than the smooth slippery teflon on greenglides.
Secondly, the wand is so light it doesn't give you any down-force. You need some weight in your wand head. When we put Goron's 12" westpak with greenglide on the end of that vac hose I was extracting literallyu holding the wand between finger and thumb, compared to wrestling the greenhorns with both hands and gettign a bad back in the process!!
