Our Verdict

Roborock S4

iRobot Roomba 694

The Roborock S4 is superior to the iRobot Roomba 694 for most uses. The Roborock has fewer parts needing regular cleaning, a larger dustbin, a longer battery life, and more advanced automation capabilities. It also performs better on bare floors and low-pile carpets and does a better job maneuvering itself. However, the Roborock isn't suitable for cleaning high-pile carpets, unlike the iRobot.
