Our Verdict
iRobot Roomba i8+
iRobot Roomba j7/j7+
The iRobot Roomba j7+ has a more advanced set of automation features than the iRobot Roomba i8+. Not only does the j7+ share the i8+'s self-emptying capability, but it can also identify and react to hazards like pet waste in real-time. It also feels better built. However, the i8+ delivers better overall debris-pickup performance across a range of surfaces.
