As I posted below, one of the recommendations to reduce energy costs in my system is to switch to a different cleaner called The PoolCleaner. It can be seen at http://www.thepoolcleaner.com/index.html

It is a suction-side cleaner that runs off of even a lower-speed pump, allowing me to run a variable speed pump on a lower setting and still clean the pool. I tried it for a few days and loaded the pool with everything that was in my Polaris bag plus some twigs and such from the yard (to simulate debris from a winter storm). It worked pretty well, and would definitely save on energy costs, but I am wondering if anyone has seen these.

I would use my current pressure-side sweep line and replumb it for suction-side use while some other plumbing gets optimized/repaired.
