Our Verdict
iRobot Roomba i4
iRobot Roomba j7/j7+
The iRobot Roomba i4 and the iRobot Roomba j7 each have advantages, meaning one might suit you better than the other, depending on your needs. Both vacuums are compatible with self-emptying stations. That said, the j7 does feel better built, delivers better performance on high-pile carpets, and has a more advanced navigation system that allows it to identify hazards like pet waste. Meanwhile, the i4 charges faster while offering similar battery life, incurs lower recurring costs, has fewer parts that need regular cleaning, and clears more debris on low-pile carpets.
