Hello, I am a newbie and have aqua leisure 18x48 donut pool. I have seen a few posts where it was mentioned that to vacuum pool you can rig up to work with your filter pump. Can you tell me how to do this? I have low water pressure at my home and have purchased several different pool vacuum heads but just don't have the pressure to clean. Or any other suggestions? I also saw where someone used their shop vac and then removed the hose? I do not understand how this would work. If there is already a post on this just direct me to it. Thanks so much!
