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.

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.

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.
