A cordless vacuum is one of those splurges that will make you wonder how you ever lived without it. The $170 Vipsun Cordless Vacuum Cleaner is on sale for $90 for Prime Day. One shopper loves it so much, they tout, "I'm a repeat Dyson buyer: choose this one instead."

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.

The other V11 deals kicking around this Prime Day are on the Extra model. This costs $50 more at the discounted prices, but comes with quite a few more detail tools. On top of those included with the Origin, you'll also get a Combination tool, Stubborn dirt brush, Up-top adaptor, Extension hose, Wand clip, and Mattress tool.
