This is actually a interesting question and it depends who you ask.
After Leaving Electrolux I went to work for a appliance repair company called Lanzon which had its roots based on been a Hoover service centre in the early 50's . I got a chance to meet one of the original owners , Who had a passion for vacuum cleaners. If you asked him were Hoover lost the plot with vacuums, he would tell you straight out , The Concept one , biggest pile of S#!T he had ever seen, ( only time I had ever heard him swear )
Now my boss in those days would tell you the Hoover turbo power was the worst hoover vacuums, were they started making cheap junk, ( funny both the concept one and turbo power made that company and its owners very rich from all the repairs.
I like the wind tunnel , I own about 10 of them in various models, which I love because apart from on small 1300 model the rest were never sold in my country.
Even their current range has some gems in it, My current daily driver is a Hoover air windtunnel which is also from the USA and has been doing duty in my home for 2 years with no issues, and it does not lead a privileged life.I ther was ashamed when I cleaned the filters the other day after my son said it was not sucking as well as normal.
Its the one of the right,pic from just after I got it.
