Poking around on the web looking for information on my older model Kirby I was shocked to read all the negative comments by people who recently bought a modern Kirby Vacuum. It seems they immediately complain about how difficult it is to use compared to other machines. I also learned that Warren Buffett’s gang at Berkshire Hathaway owns Kirby , never knew that ? One women stated she paid $4000 for her Kirby, how often does someone justify that price for a vacuum ?
