Our Dyson Animal recently exploded and as we weren't overly impressed with it, we have replaced it with a Vax, this one:

It seems fine on our hard wood floors but when I went to use on the bedroom carpets, I could hardly push it - forwards is just about ok but it doesn't pull back smoothly at all, I have to pull it back with some force. Its like the suction is incredibly strong, a good thing in once sense as it certainly cleaned the carpet well, but it wasn't a smooth action. I have a bad lower back and could really feel it after vacuuming just two rooms. I can't imagine someone with a worse disability or an elderly person using it at all, its that hard to move.
If that makes sense to anyone, or if there are fellow Vax owners out there, I'd be interested to hear if that's normal!!
TIA
