I have a pool that was re-pebbled last spring and have used the TFP methods since with good success. I brush the walls about once a week and use a pole-vac through the skimmer about once every two weeks. I have an in-floor pop-up cleaning system. I do notice that when I brush the walls or floor that it does kick up some dust/debris. Otherwise the pool looks great. Do you guys recommend the addition of a robot vac with this system?
