Oh boy, open a can of worms. Kirby lovers swear by theirs, Miele swear they are the best, Dyson lovers, ditto. Consumer Reports does not like any of those three. The Sears one (which one I don't remember) got good reviews. I've had an Oreck, it was OK for quick jobs, but dog hair did a number on the brushes and in turn tore the rubber belt. I got real good at replacing them. Eventually the machine fell apart as I was cleaning dog hair so frequently. I have a Rainbow which I like for baseboards, walls, etc and some carpet cleaning. However, my new Dyson does outdo the Rainbow on the carpet but I hate it for walls, area rugs, etc. (it is super powerful but awkward) The Dyson clogs with dog hair and their instructions aren't real good about finding the clog......it wasn't where it said it was but when I discovered where it was and super easy to access, Dyson 28 is back to being a good friend.......for awhile.
Dyson. Best one I have ever had. Very strong suction even after 3 years.
My fav is a brand called Simplicity. They cater to commercial users but it's a great vacuum for home use as well. Mine is an upright. They are made in the USA, which I think is an excellent additional aspect to their quality. It's nice to buy something made by American workers.
Any brand that is with a bag-less HEPA filter is the best ( if you're asking which cleans the best ) For best value I am not sure what your financial budget is.
