I cannot find the original post, but I remember somewhere someone said the the Dolphin filter bags are rated at 20 microns and the Aquabot bags are rated at 2 microns.

Will the Aquabot bags fit the Dolphin? If so, is there any reason why I shouldn't use them instead? I cannot imagine another bag doing any better than my Dolphin bag. It truly picks up all the fine dust and sand from the bottom of my pool. But if there is a better bag out there, I'd sure like to try one.
