Thanks for the suggestion. I'm also interested in your results. I only have one skimmer in my 18x36 inground pool and it has a hard time keeping up. I'm looking for something to supplement it.

I don't think the skim shark actually sucks the debris. I think it just moves around and the debris ends up in the "mouth" of the shark. So the battery power just causes it to "swim" around. I'll wait for your results though on the pool skim. Thanks.
