HELP !! Correct size belt for a Hoover U652A in UK ??

[electrolooks]

Hi All.

Can anyone tell me the correct size belt ref I need to fit my Hoover U652A upright cleaner ?

I recently ordered a pack of 2 via Amazon which were marked as being for this model of vac, but they are definetly far too small/short in length ! I have tried a vac shop in the UK and they are as baffled as I am as to why the belts supplied nowwhere near fit my cleaner ?

Thanks !
