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.

Half-price deal alert! We don't often see deals like this on the best robot vacuums, but thanks to Amazon Prime Day, you can snap up the Eufy G50 Robot Vacuum Cleaner at Amazon for £99.99 (was £199.99).

Samsung’s jet 95 pro is reduced by 55 per cent in the Prime Day sale, saving you more than £350. With 210w of suction power, a spray spinning sweeper and pet tool attachment, it’s built to tackle stubborn dirt and pet hair on all surfaces. It also boasts an impressive 60-minute run time, so you can clean the whole house on a single charge.
