Shop Certified Open Box Dolphin Pool Cleaners
A Certified Open Box Dolphin is a customer return with fewer than 10 hours on the motors. Each robot is inspected, tested and certified before it goes back in the box, so it arrives working like new — and because we're an authorized Maytronics dealer, it's covered by the full 2-3 year warranty and our 30-day trial, exactly like a new unit.
This is the smartest way to get a current ProLine™ or Max-Series™ model for hundreds less. Want to save even more? Certified Refurbished robots have a few more hours and the deepest discount. Quantities are limited to what's been returned, so stock changes daily.
