What to know.
The M600 features a refreshed, modernized design, including a new LED light location, a sleeker drive system panel, and matching handle and bumper colors for a more uniform look.
While the exterior has been enhanced, the M600 maintains the same trusted Dolphin performance. It continues to operate with the proven CleverClean™ algorithm, dual-drive motors, and the PowerStream system to deliver reliable, efficient pool coverage.
In addition to the cosmetic updates, the M600 now features two new capabilities: a water temperature indicator and an advanced three-level filter indicator, both accessible through the MyDolphin™ Plus app. These enhancements expand the robot’s functionality, providing added convenience and helping you get even more out of your Dolphin pool cleaner.
