My polaris 360 likes the deep end and the edges, but won't go to the center, shallow part of the pool. I've adjusted the small jet initially to the two-o'clock and hence forth between 12 and 3 in small increments. I clean the sock when there is about 1/2 to 1 cup of debris. Mostly un dissolved chemicals and some grit. It just seems to like living deep and on the edge. Could it be a personality trait?
See my pedigree for description of equipment.
My pool is balanced fairly close. Sometimes I imagine I can see the bottom of the deep end.
