IMPORTANT: Make sure you read and follow all safety instructions
and labels from your ladder manufacturer before attempting to use
Looj. Failure to do so may result in serious injury or death.
Ladder Safety
• iRobot Looj enables you to clean a single run of gutter with one ladder
position. Choose the safest ladder position possible along each run. Safe
ladder positions are away from power lines, tree limbs, or other hazards,
and provide a level surface to rest the ladder.
• Always inspect the ladder before you use it. Never use the ladder if it is
damaged, broken or bent.
• Make sure the ladder is away from electrical wires, tree limbs, doors, or
any other hazards when it is extended.
• Do not lean over the side of the ladder when using Looj. Never over-reach.
Keep yourself balanced and centered over the ladder at all times.
• Keep both feet and one hand firmly on the ladder while placing Looj in the
gutter and operating Looj.
• Keep the handle on Looj when placing it in and removing it from the gutter.
• Do not place Looj in the gutter while standing on a roof unless you are
secured to the roof with a safety harness in accordance with the harness
manufacturer’s instructions.

10 iRobot Looj 300 Series Owner’s Manual
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 flexible four-stage auger to remove
clogs, lift out 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
2” above the bottom trough.
Tip: Remove items such as baseballs, large rocks, and tree branches
by hand. Attempting to force Looj through solid debris could
damage the robot.

Handling Dense Clogs
Looj can handle most debris found in your gutter. Occasionally, there may be
heavy debris that will not clear in a single pass. Should this situation arise,
it’s important not to force the robot into the debris.
To handle heavy clogs, leave the auger on and drive the robot slowly forward
until the auger contacts the clogged debris. Press the forward button twice
and hold to proceed at half speed. Allow the auger to eject a small amount
of debris. If Looj gets stuck, reverse direction and allow the auger to clear
away the debris that have loosened. Repeat this process until the clogged
debris is fully cleared.
CAUTION: If Looj begins to climb up over debris, STOP MOVING THE
ROBOT FORWARD and back it up. If you drive the robot over debris and
up the side of the gutter, you risk it falling out of the gutter which may
cause injury. Never let anybody stand below the gutter during robot
operation.

Maintenance
Cleaning Looj
Make sure the battery door is securely closed before cleaning. Looj is
designed to be easily cleaned with a hose or under a faucet. No chemicals
should be used to clean Looj. Prior to cleaning, remove the remote control
handle and treads from the robot. Clean any debris from Looj’s wheels.
Looj’s remote control handle should be cleaned with a damp cloth
only. The remote control handle is not waterproof. Damage may occur
to the electronics if it is sprayed with water or submerged.
CAUTION: After the battery is removed, wipe edges of battery
compartment door with a dry cloth to ensure proper seal.
CAUTION: Always keep the battery door closed when cleaning the
robot to avoid damage to the product or battery. The battery is not
waterproof so water will cause battery damage.
Storing Looj
Store iRobot Looj and its battery between 5˚ - 25˚ C (40˚ - 80˚ F).
Excessive heat or cold may reduce battery life and product performance.
For best results, we recommend removing both the battery from the robot
and the batteries from the remote control handle when the product is
stored. Store Looj and batteries in a dry location.
CAUTION: Dry the robot thoroughly before opening the battery door.
Do not allow water to get inside the robot.
