I am constantly getting dirt in the deep end of my pool and keeping it clean now is becoming a losing battle. I have a Hayward Automatic Vac that I am using every few days to clean up the dirt and sometimes I use the manually vac. Should I be using the automatic vac or the manual vac? I prefer the automatic vac as I just let it go and it is less labour intensive. However, I still have to watch that it doesn't get stuck and create a possible tear in my liner from the suction. Sometimes I use the manually vac if I just want to get rid of the dirt in the deep end. Does it matter which I use?
