The Hercules Power Rated 5000 is ideal for small commercial swimming pools like those found at hotels and motels, and pools incorporated within health clubs. The Hercules Power Rated 5000 will automatically brush and vacuum the walls, sides, steps and even the waterlines of commercial pools. The on-board pump filters 4,225 gallons of water an hour, trapping dirt and debris as algae in its self-contained reusable two micron filter bag. And the Hercules Power Rated 5000 automatically shuts off after five hours of operation.
