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.

We're on record as being big fans of the Dyson 360 Vis Nav robot vacuum cleaner, which sits at the premium end of the market and, as such, offers a pretty incredible range of features and tricks to keep your home looking clean.
