The Orecks do remind me of the very old fashioned Hoovers!
I had an old reconditioned hoover for years which lasted me well as my dad was always able to mend it when it threw a wobbly!
I then went onto the lightweight upright Dyson after a brief relationship with an Electrolux. It did seem to clean well, but it's had to have 2 of those attachments which connect the wand to the main body when you're using the tools. And the wand is forever falling off/coming unattached from the main body when you're trying to hoover above your head (cobwebs and the like) and this got to the point where it annoyed me so much I ditched the Dyson. I also had to have a new wand when the Dyson fell over and a badly positioned clip fractured the plastic near the top of the wand (loss of suction).
Now, after being a hard line upright cleaner fanatic, I've got a Morpy richards storm pets which I got cheap on ebay and I love it! The tools are always there, I don't seem to fall over it, I don't get backache with it and it's light enough for a child to carry about and do the hoovering with too - yes I like to employ underage slave labour i.e. my son who is brilliant at vacumming in those little places my achy bones can't manage - and stairs.
It gets up all the cat hairs and my long hairs and none of that having to get the roller out and cut the hairs off as with an upright cleaner!
