Enjoy smarter and cleaner results with the iRobot Roomba Combo J7+ Robot Vacuum and Mop. This robot vacuum picks up dust and debris and mops at the same time on hard floors and when the vacuum detects carpets or rugs the back arms fold up and the mop is put away so that it can still vacuum the carpet or rug without leaving a wet mess. The Roomba Combo J7+ is so intelligent, that it can recognise and avoid obstacles including clothes, shoes and towels. This hands-free vacuum and mop can be paired with Alexa so that cleaning can be controlled with your voice and it also works with other voice assistants and the iRobot Home App. Once the Roomba Combo J7+ is done cleaning, it docks itself and automatically empties itself for up to 2 months with the Clean Base Automatic Dirt Disposal system.
