This Prime Day, you can score major discounts on robot vacuums from top brands including Shark, iRobot and more. These are the best Prime Day robot vacuum deals to shop.

At $399.99 for a limited time, this is the lowest-ever price for the iRobot Roomba Plus 405 Combo according to price tracker camelcamelcamel. This isn’t just another “vacuum that also mops” either; it’s a serious deep-cleaning machine with suction, scrubbing, and smart navigation that’s surprisingly advanced for the price point.
