The Auto-Adjust cleaning head automatically adapts is height to keep the Dual Multi-Surface Rubber Brushes in close contact with different floor surfaces, effectively cleaning carpets and hard floors. The patented AeroForce 3-Stage Cleaning System uses tangle-free Multi-Surface Brushes and Power-Lifting Suction with 5x the air power* to pull in embedded dirt, debris, and pet hair from wherever it hides. Patented Dirt Detect sensors recognize concentrated areas of dirt, like in high-traffic zones of your home, and provide additional cleaning in those spots. iAdapt 2.0 Navigation with Visual Localization helps Roomba seamlessly and efficiently navigate an entire level of your home and keep track of its location. And with a full suite of smart sensors and a low 3.6" profile design, Roomba can vacuum where dirt and dust hide, navigating around furniture and under beds, sofas and other hard-to-reach places. Tangle-free Dual Multi-Surface Rubber Brushes handle pet hair with ease, reducing hair tangles and brush maintenance. The high-efficiency filter captures 99% of all allergens, pollen, and particles as small as 10 microns. Runs continuously for up to 75 minutes*, then automatically recharges and resumes cleaning to complete the entire job.
