Why corded wins
Corded Dolphin keeps cleaning when a WYBOT needs to recharge.
WYBOT removes the floating cable, but adds charging time, finite runtime and battery care. Dolphin Max-Series™ and ProLine™ stay ready for repeat cycles with reusable filtration and an authorized-dealer service path.
C2 runs on a battery
- No floating cable, but the robot must recharge after its available battery is used.
- Runtime: Up to 180 minutes in Eco mode
- Recharge time: 3 hours
Corded power keeps the next cycle ready
- No charging delay or finite battery runtime.

Choose a Max-Series™ or ProLine™ Dolphin when immediate repeat cycles, no traction-battery charging routine and Maytronics' dealer-and-parts network matter more.
