The Roomba� i4+ robot vacuum helps take vacuuming off your mind� cleaning in neat rows, emptying itself, and learning your habits to offer up personalized schedules. After each cleaning, it empties itself into a Dirt Disposal bag that takes up to 60 days to fill, so that you can forget about vacuuming for months. The i4+ uses 10X Power-Lifting Suction* and Dual Multi-Surface Rubber Brushes for an impressive clean. Using the iRobot Home App or just your voice with Google Assistant or Alexa, you control when your robot cleans. With the i4+, you can check vacuuming off your to-do list. *(compared to the Roomba� 600 series cleaning system) *(Alexa and all related logos are trademarks of Amazon.com or its affiliates.
