Oops - rubbish Hoover - what are my rights?

[JeremyVile]

Bought a Hoover vacuum cleaner from Currys in feb.
Its been overheating and cutting out very easily from the start.
Its bagless and from reading the booklet it sounded like the filters were getting clogged up and needed washing even though it says that every 3 months is recommended.
Next door have been having extensive building work done and my house has been literally covered in dust. I therefore assumed that there was just too much dust going in at one time and that once the works next door finished it would deal with normal levels of dust fine.
In the meantime, i carried on using my old bagged cylinder instead - no filters to clog up, just have to keep changing the bag.
Well, works now finished, normal dust levels resumed but the new hoover is still overheating and cutting out. On top of that, when i use the hose for the stairs(bumph states that it can extend to hoover a 13 step stair case - mine has 9)there is hardly any suction at all.
Under both Currys faults policy and Hoovers guarantee, as its within the first year both offer to repair any inherent faults.
Have now done a bit of research on this product and it seems like it cuts out very easily anyway, so i'm thinking that maybe there is no fault to be repaired...its just a rubbish vacuum cleaner!
If thats the case, what rights do i have? Can i say that i just want a refund as its not fit for purpose - particularly the stairs thing. Or because of time lapsed have i missed the boat and am now stuck with this bloody thing?
Any advice greatly recieved....want to sound knowledgable when i speak to them!

I think you're well within your rights (all the products have the 1 yr guarantee)to either see if they can physically repair it or if not, they should replace it with a new one. If the new one did the same thing then they should refund your money.
It's not doing the job it's supposed to do -who wants a hoover that cuts out regularly- and you're well within your rights to ask for your money back.
TBH, I wouldn't bother seeing if they can fix it and go for asking for a full refund, stating also that it didn't do what it was supposed to do by way of the stair cleaning thing.
By the way - they might try to say you need to contact Hoover and sort it out with them, but you don't. Curry's sold you it and it's up to them to right the problem.
I recently read a very similar thing in a mag and they kind of said the above.
