All parts are perfect except the roller. The roller on the other hand is too tight which causes my robot to stop working within a minute of starting and showing an error code like something is stuck in it. After reading other reviews, one in particular, I decided to cut out the yellow part as it seemed to be the culprit. The reel seems to move more freely now, so hopefully this will resolve the issue. However, I won't know until the robot is charged and running. I will try to update my review later. (Model-1001AE)
