Our Verdict
iRobot Roomba 675
iRobot Roomba i4
The iRobot Roomba i4 is better than the iRobot Roomba 675. The i4 delivers better cleaning performance on bare floors, low-pile carpets, and high-pile carpets. It also maneuvers more effectively thanks to its smart-pathing navigation system and has a far more advanced suite of automation features. Meanwhile, the 675 is slightly easier to pick up and carry to another room, incurs fewer recurring costs, and has a slightly longer runtime, though it takes longer to recharge.
