Just wanted to put my review of the Polaris 360 in. It is a pressure side cleaner that requires no additional booster pump. It filters into its own bag so what it vacs doesnt go to the filter. We just recently installed a fiberglass pool and almost decided against the pressure side upgrade, but sure glad we didnt. It is so easy..just plug it into the fitting and let it go. The pain of manual vac is getting the air out of the line all the time. I still manual vac once every week to get the sand/dirt still remaining since we havent finished our landscaping and have lots of sand here in NJ at the shore. I give the Polaris 360 a high recommendation. Hopefully others feel the same way.
