Dolphin Explorer E20 FAQ
Explorer E20 vs. Dolphin E10—what's the upgrade?
The Dolphin E10 cleans the floor only on a 1.5-hour cycle (40-ft cord), whereas the Explorer E20 climbs and scrubs vertical walls, runs a 2-hour cycle, and includes a longer 50-ft cord.
Does the Explorer E20 have a Weekly Timer?
The E20 uses a simple one-touch On/Off power supply. For a built-in Weekly Timer at a similar size, check out the Dolphin Cayman or step up to the Explorer E30 Wi-Fi.
Is it safe for vinyl and fiberglass pools?
Yes—its soft tracks and active brush are safe on vinyl, fiberglass, gunite, plaster, and tile.
