"The Looj does not move on it own like the Roomba does, instead there is a remote control that controls the direction that the auger spins and the direction that the Looj moves (forward and backward). Because it requires constant human interaction I am not even sure I would classify it as a robot, rather it is more like a remote controlled car.
writes "Many of us have seen robots in the movies and wondered how long it would take for them to become a reality. Some of my favorites when I was a kid were Short Circut and Runaway. iRobot is a company that is striving to bring some of that technology home today. Their most popular and well known product is the Roomba vacuuming robot. The Roomba is great, after I finished my review of it and sent it back I went out and bought one. It does its best work picking up pet hair. They just came out with another robot called the Looj. The Looj is used to clean the rain gutters that go around your roof. If you have ever had to do this by hand you know how much of a pain it is. This robot uses a 3 stage auger to break up clogs and sweep all the debris out of your gutter. It is also water proof so you don't have to worry if you have water in your gutter, just don't stand below it when it is cleaning or you will get sprayed."

I recently got my hands on one and put it through my gutters. It did a fairly good job. I did have to go over some spots more than once to get all the leaves and dirt out, but in the end my gutters were a lot cleaner after it was done.
The price is also very good. At $99 for the base model it is cheap enough that you can pick one up just to play around with. The more expensive models only give you extra batteries and augers, so you are not missing anything if you go with the base model.
I only found two things about the Looj that I did not like. First, it will not turn corners, it is way too long and not flexible. Second, if you want it to move you have to constantly hold down the forward or backward button. As soon as you let go, it stops. If you could lock in the movement then you could do other things like move your ladder to the next corner while it was cleaning."
