Interesting. Gives me less confidence in the builder. He spec'd a separate line for the automatic cleaner which led me to believe it would run off the two-speed filter pump. I also asked him point blank if the the 380 could operate correctly while the filter pump was in low-speed mode. He said that he didn't think so.

The builder is actually the president of the local (and only) pool construction company. I'm not sure how involved he is in the technical details of the construction.

Anyone with an idea of the energy efficiency of the pressure-side 380 with its own pump versus a plug-in cleaner like the Dolphin. Thanks again.
