Prime Day is nearly as good of a time to buy a robot vacuum on sale as Black Friday. It's the first big sale event of the year for many 2025 robot vacuums that just came out in the spring after being announced at CES — most of them were far too fresh to go on sale for Amazon's Big Spring Sale in March.

Here, we’ve rounded up the best Prime Day discounts on robot vacuums from popular brands like Roborock, Dreame, Eufy, and more, so you can easily find the perfect one to fit you

Our top pick for a more versatile robot vacuum, the Eufy E20, is an impressive $270 off for Amazon Prime Day. The Roborock Qrevo S, which we consider the best overall robot vacuum, is 38 percent off, saving you $300.
