The Included Automatic Dirt Disposal Unit takes convenience to a New Level with the I7+. By Automatically emptying the bin into an enclosed, disposable bag that holds 30 robot bins, you don’t have to think about vacuuming for weeks at a time! Roomba i7 is also the only Robot Vacuum that can be scheduled to clean specific rooms by name. On First Use, the i7 uses it's full range of sensors to map out your floor and the world around it. Roomba then uploads the information collected by its sensors to the iRobot HOME app to allow you to properly name each room. You can merge, split and label rooms as you see fit. After that, you can schedule the Roomba i7 to clean certain rooms at certain times, or have the robot clean an entire level of your home. The Roomba i7 can remember up to 10 unique floor plans. You can then direct the Roomba i7 to where you want it to clean by voice commands using Alexa-enabled devices or the Google Assistant. As an added bonus, the iRobot i7 will automatically orient the vacuuming pattern to match the orientation of the room. So you come home everyday to the perfect vacuumed lines in your carpet! The i7 easily moves and cleans around obstacles, under and around couches, and along walls ensuring a thorough cleaning. The molded, soft-touch bumper cushions the contact between Roomba and furniture, walls and other objects while accurately discerning soft barriers from solid barriers, allowing Roomba to go under curtains, bed skirts and couch skirts. Dirt and dust can't hide from the 3-Stage Cleaning System. Dual Multi-Surface Brushes, a specially designed Edge-Sweeping Brush, and suction, attack everything from small particles to large debris on your carpets and hard floors. The High-Efficiency Filter locks in and captures 99% of cat and dog allergens, allowing allergy sufferers to breathe easy. And when compared to the old 600 Series Aerovac system, the i7 provides 10x the suction power, giving you the best suction to clean your house with!
