Dolphin E10 has a published maximum pool length of 33 ft; the other model does not have a verified length in our source material.

Controls and day-to-day ownership

Price, warranty and the decision
Blue Helix One is listed at $579 and Dolphin E10 at $499; Dolphin E10 is $80 less. Each lists a 2-year manufacturer warranty. Blue Helix One and Dolphin E10 each have a specific fit, but neither is the Pool Express pick for this job. Our better alternative is Dolphin Cayman.
