iRobot has been known as a robot vacuum standard since its launch over 20 years ago. Today the company announced a complete redesign of almost its entire product line, with new entry-level, midrange, and high-end robot vacuums. Almost every model features an AutoEmpty Dock and mopping variant to round out the Roomba catalog.

Alongside the new navigation, iRobot has added rotating discs to the Plus 405 and 505 Combo robot vacuums which allows them to lift up the mops to avoid getting carpets wet. The new iRobot Roombas also have 7,000Pa suction power and will come with AutoWash docking stations for emptying and self-cleaning.

While other brands are busy attaching arms to their robovacs, iRobot's understated innovations are more genuinely useful.
