Our Verdict
Roborock E4
iRobot Roomba i3
The Roborock E4 is better than the iRobot Roomba i3. The Roborock has fewer parts requiring regular cleaning, incurs lower recurring costs, and delivers notably better performance on bare floors and low-pile carpets, especially with pet hair. It also has a longer battery life than the iRobot, though the Roborock takes much longer to recharge. The iRobot, meanwhile, has a self-emptying function that allows it to dump debris from its internal dustbin into an external dirt compartment on its charging dock.
