We've rounded up the best Prime Day robot vacuum deals that you can still shop, including editor-tested favorites from iRobot, Shark, Eufy, Eureka and more.

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.

Amazon Prime Day 2025 is an extended four-day event this year, lasting from July 8 to July 11. One of our favorite robot vacuums, the Eufy E20, is currently 42% off. We’re seeing very significant discounts of up to 50% off editor-tested and recommended models, saving you $300 or more on top designs.
