The Eufy 3-in-1 E20 robot vacuum—our pick for the most versatile robot vac on the market—is currently 46% off on Amazon. We’re always looking for new ways to clean our homes, and robot vacuums undoubtedly play a significant role in that equation. “The Eufy E20 is one of the more unique robot vacuums we’ve tried. It has a clever 3-in-1 design that transforms it from a robot vacuum to a handheld vacuum or a stick vacuum, depending on your needs,” Amber explained. The crevice attachment is stored directly on the body of the robot vacuum, so you don’t have to fetch it from storage.
