We have a brand new Active 30 and a 35K inground pool. Crappy cover, should have replaced it, let in lots of leaves & silt. We've been vacuuming & scooping every day for a week. There's still some dark spots but can't see the bottom. The bot is coming up all but empty every darn time, cycling it 2x/day. It's picking up a few leaves here & there, but I feel like the basket should be full. We've tried both the coarse & the fine filter, no difference. When we pull it up, there's a trail of leaves in the pool behind it but nothing in the basket. I've cleaned the impeller after every cycle, I've checked the rotors... it's like the thing just doesn't work. Never mind that it seems to only want to stay in the deep end, but that seems to be a common problem. Any ideas, or should I just return the Dang thing?
