Roborock S6 vs iRobot Roomba i3

The Roborock S6 is better than the iRobot Roomba i3. The Roborock is better built, is less demanding in maintenance, incurs fewer recurring costs, maneuvers over obstructions like electrical cords with less difficulty, and delivers notably superior performance on bare floors and low-pile carpets. It also comes with a mopping attachment, though we don't currently test that feature. Meanwhile, the iRobot features an automatic dirt disposal function, as it can empty its internal dustbin into an external dirt compartment built into its charging dock. It also charges faster than the Roborock, though its maximum runtime is much shorter.
