So, I have SLAM'd the pool and the water is crystal clear. The bottom of the pool, however, is dirty with stuff that has settled over the winter. I was wondering if I should brush this and rely on the filter to clean it out over time or if I could put the robot in to take care of it? Will it be too much for for the robot? I have the Dolphin Nautilus. Just wondering what the best plan of attack will be to clean it the rest of the way. Thanks in advance and God bless!
