Had one come to my door and actually told me that if I let him give an example of the Carpet Cleaning device that comes with the Kirby Vacuum. He would receive $ 30.00 from his Company as part of his pay income. So I thought what the heck I needed a room cleaned anyway. So I let the guy clean my carpet and he got the $ 30.00 from Kirby. We both came out a winner and he thanked me and left.
