Maxed-Out Coverage
50 ft is the maximum rating for ProLine™ Dolphins, so this is flagship-only territory. The Sigma and Premier bring commercial motors and long cables; the Quantum offers the biggest filter. At the limit, setup details matter: center the power supply on the long side and keep the full cable uncoiled so the robot reaches both end walls. 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.
Our Picks at 50 ft
- Dolphin Sigma — gyroscope scanning wastes no cable on redundant passes; app control for a pool this size is genuinely useful.
- Dolphin Premier — commercial motors keep suction strong across a long cycle; best with heavy debris.
- Dolphin Quantum — the XXL MaxBin™ means fewer mid-cycle basket stops on a big pool.
What If My Pool Is Longer Than 50 ft?
Step up to the commercial Dolphin Wave series — rated for 60, 80, 100, and 120 ft pools. See our commercial guide, which covers the full Wave lineup, and the lap pool guide for long-narrow residential pools.
