Dolphin Premier: what it gives up
- No app or remote at $2,499, when the $999 CC Pro has an app timer
- Filter opens from the bottom, so the robot has to be turned over to empty it
- $2,499 — the Explorer E50 has app control and a top-loading filter for about half
- In-ground only, while the cheaper E50 and S300 also take above-ground pools
Dolphin Sigma: what it gives up
- The most expensive corded robot in the catalog
- Published weight, suction and dimensions match the $1,349 CC Supreme's; the gap is warranty and brushes
- 24.6 lb, tied with the CC Supreme as the heaviest corded Dolphin
- No filter-full light, which the cheaper Premier and Explorer E50 both have
- No caddy is listed in the box at this price
