My question that I'm getting different responses on. I have a 30,000 gunite pool and purchased Dolphin Premier few years back. Every opening there is always dirt/debris at the bottom which is expected . Do I still need to manually vacuum or can i just throw the robot in and let it do its thing? For the amount of money it costs it would be nice to not have to do any manual cleaning but I'm also told that throwing it in at opening will just kick everything up and the water will never clear up. Thanks
