Okay, my pressure side cleaner is ready for retirement. Part of the problem is that I just don't go to the bother of removing it from the pool. It's to unwieldy to have a mass of hose and plastic to pile up somewhere. So the eating away by chlorine makes these things last 2-3 years at most for me.

So... I'm really tempted by all the positive comments to get a Dolphin Dynamic. It sounds like once or twice a week usage is all I would need. But it's so expensive I'm considering a Poolvergnuegen 4 wheel pressure side replacement and a PoolBuster for any spots it would miss, and pocket the difference. Any opinions?
