Big-Pool Power
For 30,000 gallons — typically 20×40 ft — the Sigma's triple motors and the Premier's dual commercial motors deliver the suction and endurance you need. The Quantum handles it too, with its XXL bin going furthest between empties. As one of the largest authorized dealers and retailers of robotic pool cleaners online, we've hand-tested 70+ robots across every major brand — every recommendation below comes from real poolside experience, and every unit we sell is factory-direct with a full manufacturer warranty.
Gallons vs. Feet: What Actually Matters
Robot ratings are based on pool length, not volume — the cable has to reach the far wall. Use this quick conversion: a 12×24 ft pool is roughly 10–13k gallons, 14×28 ft is ~15–19k, 16×32 ft is ~19–25k, and 18×36 ft is ~25–31k, depending on depth. If your pool is unusually deep or long for its volume, size up.
Our Picks at This Size
The Sigma leads: gyroscope navigation covers a large footprint methodically, and app control means you're not walking out to a distant equipment pad to start cycles. Pools at this scale often pair well with a caddy for moving the robot and 60-ft cable. Larger still? See large pools and the commercial line.
