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.

The Eufy 11S Max robot vacuum delivers high-end features, like automatic suction adjustment, at an incredibly appealing price point. Its sleek and ultra-slim design — standing just under 3 inches tall — allows it to easily glide under low-profile furniture like ottomans and couches, tackling even the hardest-to-reach dirt.

I tested 15+ robot vacuum cleaners from Roborock, Shark, and more at home to find the best robot vacuum that empties itself.
