There isn’t a definite origin for Kirby’s name other than that he was originally supposed to be called Popopo. However, it’s widely believed that ’Kirby’ was adopted from the Kirby Company, a vacuum cleaner manufacturer (hence, Kirby’s sucking powers) based in Cleveland, Ohio, which sells its products door-to-door. It is owned by Berkshire Hathaway, which of course is helmed by CEO and the third wealthiest person in the world Warren Buffett. What can we say—the man’s got his hands on everything.
