The new Roomba 880 features the revolutionary AeroForce™ Performance Cleaning System. Roomba 880 removes up to 50% more dirt, dust, hair and debris from all floor types. The tangle-free AeroForce™ Extractors are virtually maintenance-free, making it even easier for Roomba to tackle daily dirt build-up.  Roomba 880 even cleans one room before moving on to the next for effortless, room-to-room cleaning. The AeroForce Performance Cleaning System AeroForce uses three technologies to deliver the ideal balance of vacuum suction and debris extraction. Ideal for homes with pets and allergy sufferers, Roomba 880 traps dirt, particulates and allergens into a sealed, HEPA style filtered bin. Here's how AeroForce works: Tangle-Free AeroForce Extractors: Dual extractors grab and break down dirt and debris from any floor type with no hair tangles for you. Airflow Accelerator: Creates a sealed channel that concentrates airflow, drawing in more debris. High-Efficiency Vacuum: Provides a 5X improvement in air power than previous Roomba generations. Effortless Cleaning Dirt happens every day. Keeping up with it just got easier. Vacuums From Room-To-Room: The Virtual Wall® Lighthouse™ contains Roomba in one room until it is completely vacuumed then directs Roomba to clean the next room. Can also block off-limit areas. Docks And Recharges: Roomba returns to its Home Base® to dock and recharge. Cleans On Schedule: Roomba can be preset up to seven times per week. iRobot® XLife™ Extended Life Battery: iRobot® XLife™ Extended Life Battery delivers twice as many cleaning cycles as previous Roomba batteries, doubling the time before you may need to replace your Roomba battery.* Compatible With Select Existing Accessories: Roomba 880 is compatible with existing Roomba Virtual Wall barriers, Virtual Wall Lighthouses and Remote Controls. iAdapt® Responsive Navigation Technology In coverage tests, Roomba out-cleans the competition thanks to iAdapt Technology, iRobot's advanced system of software and sensors. Finds Dirt And Debris: With Dirt Detect Series 2, Roomba uses optical and acoustic sensors to find dirt and perform concentrated cleaning. Cleans Like You Would: The Persistent Pass Cleaning Method employs a back-and-forth cleaning pattern to apply elbow grease in areas where it senses excessive dirt. Vacuums Along Wall Edges: Roomba uses Wall-Following Technology to clean right up to wall edges. Won't Get Tangled: Anti-Tangle Technology keeps Roomba from getting stuck on cords and carpet fringe. Won't Fall Down Stairs: Cliff-detection sensors allow Roomba to avoid stairs and other drop-offs. Won't Damage Furniture: The molded, soft-touch bumper cushions the contact between Roomba and furniture, walls and other objects. Pushes Past Soft Obstacles: Light-Touch Bumper Technology accurately discerns soft barriers from solid barriers, allowing Roomba to go under curtains, bed skirts and couch skirts.
