As Mashable's reporter on the Dyson beauty beat, if there's one piece of advice I can offer you this Prime Day, it's to not be fooled into thinking Amazon's Dyson Supersonic Origin deal is worth your money.

A massive $300 discount brings you this high-end air purifier and cooling fan for just $350 just in time for the brutal summer heat.

Including a delightful upholstery cleaner, an on-sale Dyson, $200 off the wet-dry vacuum that flew through our tester’s gauntlet of spilled cereal and dried maple syrup, and an efficient German vacuum squeegee.
