Blade side has only 3 contact points resulting in a 3mm gap between the cleaner and the glass. This minimizes the chance of trapping sand, and thus reduces the chance of scratching, even when cleaning below the sand! Unique orienting buoyancy always keeps the magnets facing the glass/acrylic for easy retrieval.
Plus, Flipper is nearly neutral buoyancy so it does not sink like a stone if the magnets are disengaged.
