I have a Hoover. I had a Kenmore and Electrolux. I hate them all. I finally went to Sears and bought a Craftsman Shopvac (they have a small canister style) and I absolutely love it!
All brands work well as long as they are the canister kind and not bags. Just be sure to empty when it gets full and knock the dust off the filter
I have a hoover wind tunnel vacuum. I like it very much except it seems to eat belts. I have had it about 3 months and have gone thru 3 belts. They are cheap so I don't really mind. But overall it is the best vacuum I have used.
I have cleaned houses and offices for over 20 years and I have used every vacuum cleaner on the market. I think hoover is a good brand and eureka. The one that I use for cleaning offices and I have one in my home is a Simplicity. We have a local vacuum sweeper business that sales this brand. It is light weight and it has attachments on the sweeper and are handy to get too. Also it has a good filtering system too.
hoover by far the best never had one problem with mine still has the same powerful suction it had when I bought it (2 yr ago) when the filter gets dirty you just bang it on your outside wall put it back in your hoover
