This is the only robot that removes leaves, small branches, and dirt from gutters autonomously. Made by iRobot, developers of tactical reconnaissance robots for the U.S. military, the robot’s advanced sensors detect and adapt to debris, cleaning a 30' gutter section in five minutes. The robot rotates its powerful auger at 500 rpm to break apart clogs, durable twin rubber ejector paddles lift and throw detritus up and out, and twin polypropylene brushes finish the process by wiping the gutter clean—it even reacts to stubborn sections by backing up and trying again. It can also be controlled by a 50'-range handheld remote that allows you to move it forward and backward within a gutter and change the auger’s direction of spin. The robot’s low profile fits under 2"-high gutter supports while its tank-like, belt-driven treads easily cross downspout openings; waterproof design allows for use in up to 8" of water. Includes a belt clip for transport and a rechargeable Lithium-Ion battery that provides one hour of operation from a 15-hour charge. Remote requires two AAA batteries. For use in all standard 3"-wide K-style gutters. 15 1/2" L x 3" W x 2" H. (2 3/4 lbs.)
