iRobot Roomba i3 vs Shark EZ Robot Self-Empty

The iRobot Roomba i3 and the Shark EZ Robot Self-Empty each have advantages, meaning one may suit you better than the other, depending on your needs. The iRobot has a larger external dustbin mounted to its base station, feels better built, has fewer parts that require periodic maintenance, maneuvers itself more effectively, and delivers superior performance on bare floors. It also charges much faster, though it doesn't last as long as the Shark on a single charge. The Shark also outperforms the iRobot on carpeted floors, especially with pet hair, and incurs fewer recurring costs.
