Our Verdict

iRobot Roomba i3

iRobot Roomba 694 [690, 692]

The iRobot Roomba i3 is better than the iRobot Roomba 694. The i3 can empty its internal dustbin into an external dirt compartment attached to its charging dock. It also has a smart pathing feature, yielding superior maneuverability and allowing you to check a map of its cleaning coverage or schedule cleaning sessions in advance. The i3 also delivers better performance on all surface types. Meanwhile, the 694 has a longer battery life, though this can vary in the real world.
