Question about Roomba Robotic Floor Bagless Vacuum
My Roomba does not auto dock, nor does it seem to recognize the electronic walls and lighthouse. However, when the Roomba is turned on, the electronic lighthouse/wall units turn on. They are not in line of sight, and all, Roomba and units, are about 30 feet apart and in different rooms. Isn't infrared a line of sight type transmission? If so, how are the remote units becoming aware the Roomba has been turned on? Similar to others who have described this issue, the Roomba seems to be oblivious to the docking station. It will drive all over it at full speed as if the dock isn't there. This feature did work when I first received my Roomba, and rarely it will surprise me and actually dock. The docking procedure is a unique process. You can see the Roomba aligning itself with the transmitter atop the dock, as it slowly and carefully approaches. When contact is made with both metal contacts on the dock, the Roomba issues a proud little tune, and shuts itself down. A great feature when it works, but my impression so far is that it is a gimmick prone to failure. I'd be glad to take that back if a solution can be found for this issue, but as yet that has not occured.
You may not believe this, but the new 500 series lighthouse virtual walls have both infrared and radio frequency communication. How they work and associate with the Roomba is pretty complicated. The best posting I've ever seen about how they work is here:
Check out that link to understand how the communication works.
If your Roomba is contained by the virtual walls, then you can assume the IR sensor on your Roomba us good....you should test that though. Then you might have to replace the "home base" which could have a bad IR transponder . New ones can be found for reasonable price at www.RoboticVacParts.com or you could order straight from iRobot for twice the price.
If the Roomba is not contained by the virtual walls, then the IR sensor on the Roomba is likely bad and you'll need to change the bumper on your Roomba. Again ....parts are available through ebay, or www.RoboticVacParts.com. Follow this link if you need it.
