I have a 35k IG vinyl lined pool. The pool is over 50 years old and somewhat unique. It is 20X40 with vertical walls and a continuous slope from 3.8-7.8 feet deep. Also, it doesn't have a floor drain. I currently have a Legend Platinum Pro which isn't performing very well. It doesn't climb the wall (I think because there is very little radius in the transition, basically a 90 degree angle) and stays stuck running against the wall in the deep end corners most of the time. Occasionally, when it frees itself it will traverse the pool but then angles back to the deep end and stays there. Is there a recommendation to make this unit perform better or is there an alternative that works better. The unit is 1 year old and initially did climb the walls for about the 1st week and then I think the treads wore smooth enough that it couldn't anymore. I have a dedicated booster pump and line installed. Thanks in advance for any advice.
