We are finishing up our pool design with the PB. It will be a 16.5x33.5 gunite with wet edge pebble finish, chlorine pool. The pb's basic package offers a Legend with booster pump or a robot. My wife will be responsible for the first several months of maintenance d/t my deployment training and subsequent deployment. I have never owned a pool before and don't know if we should go with the Legend and booster pump, or a robot. If robot, any suggestions? Thank you.
