Hom-bot smart diagnosis - "Please clean the obstacle detecting sensor windows"

IF YOU ARE HAVING THE SAME PROBLEM, PLEASE COMMENT!

The sensors have been cleaned, the Hom-Bot has been rebooted several times, the error does not stop occurring and the robot cleans very badly (skips rooms, hits objects etc.)

This is the 2nd Hom-Bot to have these issues (the first was replaced under warranty with the exact same failure), I have no idea what eventually causes the sensors to fail.

Update: Robot was sent to repairs (again), returned (again) and in less than a week and a half is reporting the same issue. LG, this is a joke...

Update 2: Robot is still in repairs, I keep being told I am not cleaning it correctly (a week after it returned from repairs whom claimed to have cleaned it no less).

Update 3: This robot was returned to the distributor. Since then, I have learned that the issue is due to scratches to the robot chassis (caused by the robot being square).

Newer models try to fix it by having a recess in the chassis in front of the sensors.
Here is a link to ebay with the fixed chassis (notice the closeups) - http://www.ebay.ca/itm/LG-RoboKing-LED-Window-spare-part-MKC64259602-/301561360107?pt=LH_DefaultDomain_15&hash=item4636752eeb
