Dolphin Explorer E20 or Dolphin Premium 30 — which wins?

Our Recommendations

Neither the Dolphin Premium 30 nor the Dolphin Explorer E20 is one of the cleaners our pool experts promote. Consider a proven ProLine, Max-Series, or Clear model instead — each is backed by its full manufacturer warranty and our 30-day in-pool trial.

Hands-Off Weekly Timer

An automatic pool cleaner should be automatic. A true weekly timer runs a complete pool-cleaning cycle on schedule — every day, every other day, or a few times a week — without you retrieving or recharging the robot between cycles.

Dolphin Explorer E20 does not

Anti-Tangle Cable Swivel

Say goodbye to tangled cords. An anti-tangle swivel lets the robot move 360° around your pool without the cord getting tangled, so you can sit back while it cleans. Learn more ›

Warranty Coverage

A robot is only as good as its warranty. Buying through an Authorized Dealer like Poolbots gets you the full manufacturer warranty — never pro-rated or limited by cleaning cycles — plus a 30-day in-pool trial with no restocking fees. Learn more ›
