iRobot, the makers of the extremely popular Roomba vacuum cleaning robot have just released another robot helper called the Looj Remote Controlled Gutter Cleaning robot. The Looj is not quite as set it and forget it as the Roomba but it's still pretty easy to use and definitely cool.
To operate the Looj you simply place it in your gutter and watch it blast leaves and gutter sludge away, preferably into your jerk neighbors pool. iRobot really had safety in mind when developing the Looj by making a tedious and dangerous job of struggling with the ladder and turning it into an easy 2 trips. Once up to set the unit and another up to retrieve it.
