Our Verdict

iRobot Roomba S9

Neato D8

The iRobot Roomba S9 and Neato D8 each have their strengths, so one may suit you better depending on your needs. The iRobot feels better built, has a longer maximum runtime, delivers better performance on low-pile carpets, and maneuvers itself more effectively. That said, the Neato clears more debris on bare floors and high-pile carpets, is less demanding in maintenance, and is notably lighter in weight.
