Dyson upright My Dyson cleaner suddenly screemed at me and stopped with a puff of smoke and burning smell. I had just emptied the cylinder. It is five years old.

Hi this is an expensive repair and would probably be cheaper to buy new one the problem you have is with the motor bearings seizing its expensive to repair because when dyson made thes vacs they were made so you need special tool to take them apart so replacing the motor would require calling a dyson bloke out as i found out with mine when my switch failed i tried removing and replacing myself but when the bloke came out he used a thin piece of metal down the side of switch to press button to release switch after i payed him to do this 2 months later i got your problem and called them back they tryed selling me new one as the repair was 50 quid more than a new vac.
Hope this is some help sorry i couldnt give you good news
