My e5 Roomba was a little over a month ‘old’ when it started to leave clumps of hair around rather than pick it up. We have 2 German Shedders and 5 cats - and despite having to stop the machine to empty it every 15 minutes, it has still made an incredible improvement in reducing the hair and dirt on the floor. I figured it was time for a ‘deep clean’ - and indeed it was. I removed the rubber brushes and cleaned them with water, cleaned the dirt bin using water, changed the filter, removed and cleaned the front roller. When I was done (and everything dry), I set the Roomba to start. It ran for about an hour, and then got caught in a cord under a buffet. I pulled out the cord, and the pressed start. In two minutes it stopped with an Error 2 clear the brushes. There was nothing there, started it again, and in two minutes another ‘Error 2’. [br]

I went through all the many good suggestions on this page - including removing the end bearings and removing the amazing amount of twisted hair underneath. I tried to be sure the rubber brushes were centered. Nothing seemed to work - I continued to get repeated ‘Clear the brushes’ messages after two minutes. I finally resorted to what I really didn’t think would work: I ordered the ‘replacement part kit’ with new brushes, sweeper brush, and filters.[br]

I replaced the brushes and the sweeper brush. The Roomba now works again. It seems strange that the brushes would be bad after only 1 month. Perhaps that cord catch damaged them. Regardless - the new brushes fixed this problem for me.
