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.

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.

Our editors rounded up the best Prime Day robot vacuum deals, including savings of up to 50% on models from iRobot, Shark and Eufy.
