Then, there is the Polaris LCS. See it at http://www.polarispoolsystems.com

Look under accessories, then LCS.

I have one (also a Pool Devil and wll probably get a Poolskim, too - I am desperate for more skiming action) and the results are still out. It goes on the line for a suction cleaner and needs the cleaner to move it around the pool. I found that my 1.5hp pump would not drive the LCS and Hayward Navigator enough to get very effective action. Since the LCS is on the line before the Navigator, it reduces the suction to the cleaner. There is an ajdjustment, but I have found I do not have enough power to effectively drive both. I will be swapping my 1.5hp for a 2hp soon, so maybe it will improve.
