Some of the best robot vacuums we've tested are on sale for Prime Day, including savings of up to 50% on top-rated models from iRobot, Shark and Eufy.

Prime Day is nearly as good a time to buy a robot vacuum on sale as Black Friday. For new robot vacuums that debuted at CES 2025, it's the first big sale event of the year — most of them were far too fresh to go on sale for Amazon's Big Spring Sale in March.

Right now for Prime Day, you can scoop up the Eufy Robot Vacuum 11S Max for half price. It’s normally $280 so Prime members can get it for just $140.
