• A MOP PAD DESIGNED FOR PERFORMANCE. Designed for wet floor mopping performance, the specialized microfiber pad tackles footprints, dirt and dust.
• CLEAN YOUR WAY MORE EFFICIENTLY. Fill the Roomba Combo Bin’s tank with a compatible cleaning solution* of your choice or just water and instantly transform your robot into a vacuuming and wet mopping robot that leaves your home fresh and clean. *See iRobot website for list of compatible cleaning solutions.
• UNDERSTANDS MORE VOICE COMMANDS THAN ANY OTHER 2-IN-1. Simply pair Roomba Combo i5 plus robot vacuum and mop with Alexa, Siri or Google Assistant-enabled devices* and tell it to clean the kitchen, living room, or every room.
