iRobot Roomba i7 vs Roborock S7

The Roborock S7 is better than the iRobot Roomba i7. The Roborock is better built, incurs lower recurring costs, has fewer parts to regularly maintain, and cleans more effectively on bare floors. It also has a significantly longer maximum runtime but takes much longer to recharge than the iRobot. The Roborock also has a LIDAR mapping system better suited to darker environments, not to mention a mopping module to clear away dried-on stains. The iRobot does a better job of dealing with pet hair and comes bundled with a self-emptying station at a more affordable price than the Roborock.
