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.
Summary: these do not work well with the roomba when used in lighthouse mode; wall mode works fine. The interaction between the roomba and the lighthouse units result in the roomba often getting stuck in a room, getting lost, etc.

Summary: This iRoomba 780 series has a MAJOR design flaw! It is NOT designed to pick up pet hair! We have two rescue dogs, and our floors need cleaning daily. This Roomba lasted 3 weeks before it had to be replaced. The problem is when the hair gets trapped around the axle shaft and it causes it to fail!
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!
Summary: Product displayed black but received white one. Put in batteries and did not work. No clear turn on and off button. I have another that came with my roomba and it's great. Did not stop roomba from going through a doorway.
Summary: I have had the red, the blue, and the scheduler Roomba all have directed me to the conclusion the Roomba is created to fail deliberately. Why you ask? Because after all these years the product comes out with new little quirks (improvements.
