losing suction

Just wondering, why did this guy Dyson make it his life's calling to build a better vacuum? Just how thick was this guy's carpet that he had such a problem with losing suction? Makes you wonder about his home life, don't it? "I want more suction, damn it!"

and the real bitch of it is, he's laughing all the way to the bank, and probably getting all the suction he can take. Hey, if murderers can have groupies, why not a vacuum cleaner magnate?
