Vacuum Cleaners Discussions

Hi ive been searching for a vacuum for my wife. She has had a Kirby Hoover for may years. Its a very sturdy vacuum, but it has seen its day.

All the vacuums reviewed look good. But now I cant decide and im worried I could get one a it be big disappointment.

Im not fussed on an upright or canister, just the quality. I want it to last so any help deciding would be much appreciated.  

Thanks
Carl
