I just purchased this unit and am curious as to what I should be doing with objects in the pool such as my poolskim device (connected to one of the returns) and the two floating frog logs I have hanging off the sides of the pool. As the robot moves up to the tile line, will it try to eat my frog logs? I'm guessing it would make sense to remove these prior to cleaning, but just wanted to check to see if anyone else has run across this potential issue.
