This is the only remote-controlled robot that removes leaves, small branches, and dirt from gutters. Made by iRobot, a company founded by roboticists from the Massachusetts Institute of Technology and renowned for their tactical robots used in U.S. military reconnaissance missions, the robot is controlled by a 100'-range handheld remote. After it is placed in a gutter, the robot begins to clean at the touch of a button, rotating its powerful auger at 500 rpm while the durable rubber and plastic blades dislodge and remove stubborn detritus; polypropylene brushes finish the process by wiping the gutter clean. The robot's low-profile allows it to move under gutter supports while its tank-like, belt-driven treads allow it to easily cross downspout openings; waterproof design allows for use in wet conditions. When cleaning is complete, the remote attaches to the top of the robot, forming a handle for transport to the next gutter. Includes a holster and belt for transporting the robot and a rechargeable battery that runs for one hour after a 15-hour charge. Remote requires two AAA batteries. For use in all standard K-style gutters with 2 1/4" clearance. 2 1/4" H x 3 1/4" W x 19" L. (4 lbs.)
