What is the top selling vaccum in the usa?

Question:just met with a Kirby Rep who said they were the most selling vaccum in the USA. I find it hard to believe with Lowe's and Home Depot with more than 3000 stores add in Sears, Target and Walmart all carrying the same brands--Dyson, Orach, etc. Thats more than 10,000 stores. Figure each store sells one vaccum a day! Not a chance!

Hmmmm there have got to be some stats on that somewhere.. I don't know if they still are but I think they used to be at least.
Frankly, if I had the money I'd get a Kirby. The salesdudes came to my house too and I just fell in love with it. Of course I couldn't afford it. I had gotten a cheapy of of ebay and it was a G3. Boy that thing could suck-start a Harley! After about a year it died though because I had only paid like 75 bucks for it anyway. Awesome machine though! :)
