Our Verdict
iRobot Roomba Combo J9+ solves the carpet-mopping problem that plagues cheaper robot vacuums. Retractable mop lifts automatically when carpet is detected — no damp carpet, no manual intervention. 75-day auto-empty and PrecisionVision complete the autonomous package. Roborock and Dreame match this functionality at lower cost — iRobot's brand heritage and 20-year robot vacuum track record are the premium justification.
