Am having a temper tantrum. I have a Vax Vibe Energise pet Hoover which is pretty terrible anyway but the foothead seems to be stuck. It's the landlady's so not my own and there are lots of accessories that should be interchangeable so the foothead should come off easily... except it doesn't! I've tried brute force which isn't particularly forceful as I'm quite the weakling. I've bought vacuum pack bags so want to change to the nozzle! Arghhhhh
