iRobot Roomba s9+

The Roomba s9+, while an older design, remains iRobot's most powerful vacuum. Its unique D-shape and Corner Brush are engineered specifically for cleaning along walls and into corners. It boasts the strongest suction in the iRobot lineup and excels on carpets. The Clean Base provides self-emptying.

It lacks mopping capabilities and uses iRobot's older camera-based navigation (vSLAM). This model is best for homeowners with primarily carpeted floors or who need superior edge cleaning and raw suction power. It ranks highly for its specialized cleaning performance but loses points for its age and lack of mopping in a modern market.
