He is coming back today for more readings and measurements. I am very impressed with the analysis process of this bid. They he has used an ammeter to test all of my draws under all of my conditions (solar on/off, cleaner on/off). He put a vacuum gauge on the pump to get true pressure readings in combination with my filter pressure.

I am going to grill him more on the cleaner issue and maybe even ask for the demo unit trial. I think the suction cleaner he is talking about is somehow closer to robotic than the kreepy style ones. He says it is programmable and runs a specific pattern and takes a lot less time. It has a leaf can to catch the big stuff. I don't see how it can do all of this without a power source though, but I will ask him....

As far as the switch, I just need to make sure that the flow will indeed be higher than my current flow. I need to read up on the variable speed pumps a little more.
