I currently have a Polaris 360 and the replacement hoses I have purchased are just not cutting it. I’ve tried from Amazon to pool store and all the same issues with cracks in the hoses. What is good replacement vacuum that you went to without purchasing additional booster pumps.
Unfortunately, even with the O.E.M. hoses, they do tend to crack over time. I can give you a few tips to help extend their life, though. Whenever you remove and store the cleaner, rinse the hoses thoroughly with fresh water. Also, make sure your chlorine levels aren’t too high, as that can cause the hoses to dry out and crack faster.
