Anyone looking for a Vacuum do not buy a chain store Vac, I worked in the vac business and still talk to many people who do. Dyson is a supposedly clog free unit, but is designed with clog removal ports, has a weak motor and overall a real piece of crap. Go to Banks Vacuum superstore, there all over; or go to United Vacuum on Dixie in waterfall plaza. Look at the Miele Vacuums they are spendy but by far the best Vac you can buy. If the Meile is too expensive get a Simplicity.
I have a Simplicity 7950, these things are so powerful it will rip a 3 wire 14 guage cord in two pieces, they have an excellent warranty and are just naughty.
