iRobot Looj 120 Gutter Cleaning Robot


I love my iRobot vacuum cleaner. It saves me lots of work cleaning the house. I just have to press a button and it will get the job done. It’s fall season, leaves is falling and rain starts to pour. It is time to clean the gutter. I see iRobot also makes a gutter cleaning robot, base on my good experience with their vacuum cleaner, I decided to give it a try.

I did not get the latest model, Looj 125, which is in yellow color. I spot a previous generation Looj 120, which is in green color selling cheap on Craigslist. The only difference is the newer model and the older model is an internal antenna instead of an external one the motor, the brush and everything else is the same. The Looj works amazingly in youtube, but unfortunate it does not work on my gutter at all. My gutter is not standard size, it is too wide for Looj. Instead of throwing the dirt out of the gutter onto the ground, it just flipping the dirt from the left half of the gutter to the right half and vice versa.

I have a few minor complains about the Looj. It uses Ni-Cd battery instead of Li-ion battery, so I have drain the battery completely before recharging to avoid memory effect and make sure I do not overcharge the battery. The external antenna is inconvenient. Once awhile, the Looj will flip up side down. I have to reverse the brush rotation to flip it back otherwise the antenna is on the way. Without the antenna, the Looj can move on either side. Other than that, the brush motor is pretty powerful, dirt and leaves is flying high. It should work well if mine is a standard 4″-5″ gutter instead 8″.

Since the Looj does not fit my gutter, anyone interests in buying it from me?
