After my pebble pool was filled, I bought a Dolphin Explorer E30 but NPT says not to vacuum using wheeled devices or automatic cleaning systems for the first 28 days. I've been brushing 1-2x a day since the fill, 11 days so far, but haven't been able to vacuum anything. I need to vacuum some bits of dirt in the spa and deep end of the pool from when landscapers came by, but I'm scared to jack up my pool after 4+ months of building. What do I do?
