I had a Robovac 11 purchased in July that was replaced a few months ago due to fault side sweepers. The new one has been great, however over the last week it has started bumping in to EVERYTHING. It did not do this at first, it would sense walls and chairs and slow down and go around them unless edge cleaning. Now it sounds like I have a toddler wrestling match going on every time I run the vacuum. I stopped running it at night b/c it was too loud. I have cleaned off all the sensors and it has made not difference. Am I missing something?
(PS I have seen somewhere that dark colors sometimes confuse the IR sensor, but I have no dark furniture pieces or borders, and it was working perfect before)
