[quote=G1GY;227916]Those hard nylon or plastic loops
can not scratch glass. There had to be a piece of sand or something stuck in the pad for it to do that. (Maybe it got picked up from the bottom while cleaning.)

Yes, you would think so, but there is something hard in the cleaning pad. It didn't even touch any substrate before the scratch. Anyway, I still can't see how it would clean soft algae better than the nylon felt. Now hard algae, that may be a different story.
Basically I don't think this cleaner is worth the hype. It takes many strokes to clean an area which took only two strokes with my old one. Maybe it needs a break-in period.
