The Looj 155 isn’t usually what comes to mind when you think of robots. The Looj is a small tracked vehicle with a motor on the front that turns a shaft with plastic flaps and small brushes. You set the robot in the gutter after clearing a small space for it, then detach handle, which is the remote control, and start the robot. The shaft rotates quickly and the flaps and brushes throw the leaves out of the gutter. Using a garden hose you can rinse any muck off the Looj.
