When I first ran my Evo, it didn’t pick up all the leaves on the bottom. Using the standard filter, I continued to run a couple back to back cycles per day rinsing the filter after each cycle. After about 5 cycles my pool was clean. Since then my Evo has kept my pool spotless. After storms blew through and deposited more leaves the evo picked them up without problem. The standard filter was also very good at picking up all of the little silty bits. I have the fine filter now. When I ran the fine filter for the first time yesterday it didn’t pick up as much as I thought it would because the standard filter did such a good job. I love this Evo so much! It has completely changed my pool maintenance life!
