Verdict

The iRobot Roomba Combo j5+ is a 2-in-1 self-emptying robot vacuum and mop featuring a 2210 mAh lithium-ion battery, a 389 ml vacuum bin, and a swappable 276 ml combo mopping bin. Its main characteristics include VSLAM-based PrecisionVision Navigation for real-time 3D obstacle avoidance (such as pet waste and cords) and an automatic Clean Base that holds up to 60 days of debris. Prominent pros are its effective dual multi-surface rubber brushes, proprietary Dirt Detect technology that intensifies suction on heavy messes, and a feature-rich app with custom No Mop Zones. However, notable cons include a highly manual mopping experience that requires physically swapping the dustbin for the water tank, a lack of an automatic mop-lifting mechanism over carpets, and loud operation during its self-emptying cycle.
