Product Description
iRobot Looj is a powerful robot designed to clean gutters. Looj eliminates
multiple climbs up and down the ladder. No more moving the ladder every
sixfeet,oroverreachingatdangerousheights.Loojhasanumberof
features designed to make gutter cleaning simple and easy. Looj’s
ergonomic handle detaches for wireless control of the robot. The included
belt clip lets you keep two hands on the ladder as you climb.
Cleaning Power:Therobotusesaexiblethree-stageaugertoremove
clogs,liftoutthedebris,andbrushyourguttersclean.Spinningat500RPM,
the high speed auger disrupts, lifts, and tosses debris out of your gutters.
Remote Control Convenience: The remote control gives you complete
forward and backward control of the robot. You can also control the spin
direction of the auger to make sure that gutter debris is tossed in the correct
direction, away from the roof.
iRobot Looj works in most standard gutters with straps or ties mounted
at least 2¼” above the bottom trough. Looj is compatible with standard
K-style gutters.
Tip: Remove items such as baseballs, large rocks, and tree branches
by hand. Attempting to force Looj through solid debris could
damage the robot.
