iRobot Roomba S9 vs Roborock S7

The iRobot Roomba S9 and the Roborock S7 each have their advantages, and one may suit you better than the other, depending on your needs. The iRobot has a bigger dirt compartment, maneuvers itself more easily, and clears far more debris on low- and high-pile carpets. It also takes much less time to recharge, though the Roborock has a longer battery life. The iRobot's HEPA filter also does a much better job of sealing in allergens. The Roborock is also less demanding in regular maintenance, incurs lower recurring costs, and performs slightly better overall on bare floors. It also comes with a mopping attachment that's impressively well-suited to tackling dried-on stains. Its LIDAR mapping system also makes it a better option for cleaning dark rooms.
