+1. The movement is in the first few inches of the top of water. It's not like skimming is going to suck up sand from the pool floor only for it to get stuck at that lip. Anything floating is going to float right on by the next time the door drops. Anything heavy enough to sink was long sunk.
Will it need an occasional wiping/brushing ? Probably. But nothing crazy IMO.
