Does anybody have an estimate on energy requirements between the 1-1/2hp pump the installer was recommending with the Valet 3 system and a Polaris 280 with booster pump? The installer was recommend using a VFD Pentair pump but would that offset the extra power requirements of the nozzles? I think the booster pump for the 280 is a 3/4 hp? So that would appear to be 1/2 the savings right there? My assumption is that the filter pump would have to be running while the Polaris was in operation so I would lose a little energy there also? What is the normal Polaris daily cleaning time for a Polaris 280 to clean approximately 15' X 36' pool? What do people use to clean the connected spa and steps when using a Polaris (granted the spa is only 7' X 7')? This is a Salt water pool.
