What are the best vacuum cleaners out there?
Dyson is the top brand
Dyson, bar none. I've been using one for 8 years and it still sucks like a champ.
Kirby. Mine is 25+ years old and the only thing we've ever had to do is replace bags and a belt
Commercial vacuums are best
Well you can find some of the best out here since it is really hard to choose the only model. You may want to see the functions and compare them :) http://www.bestvacuumforhardwoodfloorsandpethair.com/
