I was "scammed" into buying a Kirby vaccum cleamer about ten years ago. It has been a great product ever since. I have been treated well by the Kirby Distributor here in my home town.
The Kirby has kept my carpets clean and is very durable. I know a sales pitch when I hear one , but I sure am glad that I took the time to let them show me the demonstration.
I had no intention of buying an expensive carpet cleaner at the time but I'm glad I did.
