Black Friday is the best time to save big on a vacuum. We found deals with up to 67 percent off on popular models from Dyson, Shark, iRobot, and more.

Discounts this steep across their whole hair styling lineup is a rarity. The lauded Dyson Airwrap is now $100 off at Amazon, and the Supersonic Nural hair dryer is seeing the same substantial discount. These aren't your standard hair tools — Dyson's range combines innovative technology that protects the hair and shows proven results.

You could buy the cheapest pick six times over and still spend less than you would on a single Supersonic hair dryer.
