Hi, I have a warrior SI. I removed the cover today to find a green pool but not nearly as bad as other years. I can see the main drain at 8+ ft. My husband typically removes the return covers because they are hard to reach with a 2ft rock wall but he can't do it until later this week. I'm thinking of throwing my robot in to do some vacuuming and to help circulate the water before I take my first water test. Is that ok? Thanks!
