You can also buy many of them vs. a mediocre performing Dyson.
IMHO, Dysons are the Mercedes of the vacuum world. They may or may not actually be better, but they sure do cost a heck of a lot more.
There are tons of five started rated vacuums on amazon for under $100 that people have been using for years and years, so it baffles me why anyone would pay $400 for a vacuum unless they've been swindled by advertisements.
Watch less television if you can't resist the hype, people.
