They say there are only two certainties—death and taxes. But if you live on a wooded lot, you know that gutter clogs deserve mention on any list of things you can't avoid. Even though it's your least favorite chore, each year finds you climbing the ladder, scooper in hand, once more on a mission to clear clogs. This time around, you can make the job quicker, easier, and safer with the iRobot Looj. As you employ a remote control to guide it down the gutter, the Looj propels itself on rubber, tank-link treads, blasting through crud and sludge along its way. Available at Amazon; $299.99.
