Yes, it dit turn on the Home Base! It's strange. Since the video I've taken it apart again, because for testing it I din't put all the screws on place, so it will be easier to open in case I needed to test something.
Since it was overall working, this time I assambled it completely. Now it seems to follow the correct routine, it moves away from the base first, and then it starts cleaning.
I'll keep an eye on it anyway...

Some of those could have resulted from furniture structures that are too narrow to adequately reflect enough of the IR beams' (fanning out in front of Roomba) energy back to the robot. You might try watching your fast driving Roomba as it approaches normal (+/- 45 degrees) to a wall to see if it slows before striking the wall. That would be its normal response.
Sometimes it slow down when getting near an object, other times it bumps it. It happens with my sofa that is black and some puffs that are dark also. The white furniture it's a gamble, sometimes it hits it other slows down. Could be the sensor? It's almost 2 years old, maybe the sensor is not in good shape...

Thats why I isolated that burned Pad, there was something wrong with it. Truth is that I've been lucky with this repair, when I saw the black burned area, I don't expected to have a working Roomba in a couple of days. And even with some glitches like not slowing down on some furniture, it cleans allright and I got it for a good price, with 3 virtual walls and a remote controller. So I'm pretty happy!
