We don't cover or close because we enjoy our pool year round
Words cannot describe how well this polaris robot works....I regret not taking before and after pics..so very impressive we've had our pool 8 yrs and had a smaller model polaris, and this model is a life saver...my husband absolutely loves sitting in his chair by pool watching his new toy do its job so perfectly.....we got the 3 extra filters and it was very worth it...the pool was full of winter debris, lots of leaves and other yuck. We don't cover or close because we enjoy our pool year round..this polaris cleaned all the leave and fine silt...favorite feature is when it's time to empty the filter,  you point the remote control to the pool side and the Polaris climbs to you to lift it out..see pics of it cleaning the buddy seat...OMFG Love it
