Hi. We just got a Poolvernugen x4 suction this afternoon and have been trying to get it to climb walls. I can't seem to adjust the floats to get it to do so. I've tried moving them farther and closer, splitting them up and removing one all together. Our pool is a 28k gal diving pool. The cleaner seems to go about 1-2 feet up most of the walls before the front falls away from the wall and it sinks to the bottom. Any tips on positions to try moving the floats to? We have it running at 13rpm currently. It moves from the deep end to the shallow end fine. Thank you
