Summary: This thing does absolutely nothing. There is a light that does not even blink to let you know that the power is on. It blinks for a second when you put the batteries in, and that is it. I have already replaced this once and have tried fresh battereis.
Summary: I've tried to get these things to work, but with my layout, they don't. I've read all of the blogs and instructions and have seen the video as well. I've even tried resetting all of them by taking out the batteries. It's a nice concept if it works.
Not working as intended and not smart enough to find additional rooms even with lighthouse!

Summary: Roomba found 2 out of the 3 rooms in my apartment without using the lighthouse the first time we used it. I ended up buying 1 more lighthouse online and set each on lighthouse mode close to doorway of each room on the floor (I made sure each one was set to lighthouse not virtual wall).
Summary: It kind of works, but I learned to hate it after a few months. It depends upon a rotating brush and soft rubber flaps to pick stuff up, not suction like a regular vacuum. There's a tiny bit of suction from a small motor, but nothing close to even a dust buster.
Summary: These brushes do NOT fit the 770 series Roomba!!! I sent an email to try to return and get correct brushes. Update on this review: The seller emailed me and said to use a little force when putting on the new brush. I did and it worked just fine!
