Dolphin Explorer buying guide

What separates the models, and which current Dolphin to price each one against.

Reading the Explorer numbers

E10: floor only, pools to 30 ft, 1.5-hour cycle. E20: floor and walls to 33 ft. E25: 40 ft, floor and walls, app and timer. E30: the 2026 model with Wi-Fi and waterline scrubbing, in standard and Wi-Fi versions. E40: 50 ft, floor to waterline, 2.5-hour cycle, 3-year warranty. E50: 50 ft with Multi-Layer filtration and the app. E70: the flagship, with the Universal Caddy in the box and 3 years of coverage.

Explorer or Max-Series™?

An E30 and a Cayman cost about the same. The Cayman's HyperBrush™ and MaxBin™ win on fine debris; the E30 wins if you want app control at that price. From the E50 up, compare against the Quantum, which adds NanoFilters™ and the XXL MaxBin™.
