iRobot Roomba 870 Vacuum Cleaning Robot with AeroForce Performance Cleaning System

Dirt happens every day. Keeping up with it just got easier with the new Roomba 870. The new Roomba 870 features the revolutionary AeroForce Performance Cleaning System. Roomba 870 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. Ideal for homes with pets and allergy sufferers, Roomba 870 traps dirt, particulates and allergens into a sealed, HEPA-filtered bin. The Anti-Tangle Technology keeps Roomba from getting stuck on cords and carpet fringe. Roomba automatically adjusts between floor types to clean carpets, tile, hardwood and laminate floors. The spinning side brush cleans dirt from wall edges and those pesky crevices. XLife Battery delivers twice as many cleaning cycles as previous Roomba batteries, doubling the time before you may need to replace your Roomba battery. In addition, invisible barriers can be set using the auto virtual wall included in the system. To mark off-limit areas, simply place a virtual wall at a doorway or other opening and adjust the infrared beam setting to the distance of the opening. The unit automatically detects the beam and will not cross it. In coverage tests, Roomba out-cleans the competition thanks to iAdapt Technology. iRobot's advanced system of software and sensors enables Roomba to find its way around any shape or size of home, covering every area of floor multiple times. The molded, soft-touch bumper cushions the contact between Roomba and furniture, walls and other objects. Light-Touch Bumper Technology accurately discerns soft barriers from solid barriers, allowing Roomba to go under curtains, bed skirts and couch skirts. Cliff-detection sensors allow Roomba to avoid stairs and other drop-offs. The IRobot's Spot Clean mode provides quick clean-up of concentrated dirt and debris. Roomba uses sophisticated power management software to deliver up to 50% longer battery life than previous Roomba generations, ensuring hundreds of cleaning cycles under proper use. Roomba returns to its Home Base automatically to dock and recharge plus Roomba can be preset up to seven times per week to automatically clean when you're not around! AeroForce uses three technologies to deliver the ideal balance of vacuum suction and debris extraction. Ideal for homes with pets and allergy sufferers, Roomba 870 traps dirt, particulates and allergens into a sealed, HEPA-filtered bin. The Persistent Pass Cleaning Method employs a back-and-forth cleaning pattern to apply elbow grease in areas where it senses excessive dirt. Roomba uses Wall-Following Technology to clean right up to wall edges ensuring an even clean. With Dirt Detect Series 2, Roomba uses optical and acoustic sensors to find dirt and perform concentrated cleaning on areas that need a little more "persuasion". Airflow accelerator creates a sealed channel that concentrates airflow, drawing in more debris. The high-efficiency vacuum provides a 5X improvement in air power than previous Roomba generations. The dual tangle-free AeroForce extractors grab and break down dirt and debris from any floor type with no hair tangles for you.
