iRobot Roomba Combo j9+ Self-Emptying Robot Vacuum and Mop

The Roomba Combo j9+ is iRobot's answer to the Chinese robot vacuum invasion, and it's a strong one. The headline feature is the auto-retracting mop pad that lifts completely onto the robot's top when it detects carpet — no wet carpet disasters. iRobot's P.O.O.P. (Pet Owner Official Promise) guarantees the robot will avoid pet waste or they'll replace it. The self-emptying Clean Base holds 60 days of debris. Navigation is excellent thanks to PrecisionVision and iRobot OS, which learns your home's layout over time and suggests cleaning schedules based on your habits.
