I've been a little busy the last few weeks and have let the pool go unattended (it's pretty much post-season here in Chicago). My backyard is mostly treeless but my neighbors have massive oaks and maples and their leaves are not very neighborly. I tackled a bit of a mess this morning and skimmed everything off the top, cleaned out the skimmers, backwashed the filter and poured in a ton of chlorine. That left only the leafy bottom. My S300 really impressed the heck out of me. I had to pull it out before the cycle ended because its belly was full. The basket was so packed with leaves you really couldn't fit another in sideways. I was amazed at how well it did. 2 cycles and the pool looks swim-ready (assuming it was 40 degrees warmer outside).
