We have had our pool for 12 years and have always used a Polaris 280 for the cleaner. 2 / 280's and 3 pumps in 12 years. This is the first full year that we have has a SWG and a new liner... The time savings the SWG offers from messing with chlorine is amazing. I now have time to brush the pool daily and keep it remarkably clean. I have most likely only used my cleaner 5 times this year and 4 out of the 5 it was more of preventative maintenance to stir up the bottom than any real cleaning. Just saying the Polaris is great and before we used to leave it in the pool considering how often it was used. I know the SWG does not remove dirt but the time you gain without messing with chemicals is amazing. Just my opinion and it looks a lot better too!
