This is the only robotic vacuum that maps a room's parameters and obstacles and cleans the entire floor in the most efficient, linear pattern. An onboard laser identifies walls, furniture, and doorways, creating a digital map the robot uses to confirm where it's been, where it needs to go, and avoid obstacles that other robotic vacuums can only detect by impact. The robot begins by vacuuming a room's perimeter and continues in a human-like, back-and-forth manner without traveling over the same area more than once. Because of its methodical, efficient movement, the robot conserves power for its vacuum suction--the most powerful in a robotic vacuum--that removes dirt or pet hair in one pass. It repeatedly updates the map to account for objects that may have been moved or added to the room during the cleaning process and automatically moves on to the next room only when it's vacuumed every square inch. The robot cleans up to four rooms per charge, automatically returns to its drive-on charger when its battery runs low, and resumes cleaning where it left off once it's fully recharged. Includes an easy to remove dirt bin and two air filters. Recharges in three hours. 13" W x 12 1/2" L x 4" H. (13 lbs.)
