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.

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.

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.
