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.
S2 runs on a battery
- No floating cable, but the robot must recharge after its available battery is used.
- Runtime: Up to 210 minutes
- Recharge time: 3 hours
Corded power keeps the next cycle ready

How S2 and Active 10 compare
The WYBOT S2 is cordless and rated for up to 3,229 sq ft. It cleans floor + walls + waterline + steps and uses 180 µm basket + 40 ppi cotton foam; no micron equivalent published for the foam filtration. Runtime: Up to 210 minutes.
The Dolphin Active 10 comes from the Active™ lineup. It is rated for up to 30 ft and cleans floor with Fine filter basket filtration. Its standard cycle is 1.5 hours.
The easy choice: corded Dolphin
The S2 removes the floating cable, but it adds charging time, finite runtime and battery care to the cleaning routine.
We recommend the Dolphin Sigma. It delivers corded cleaning with no recharge delay, plus it is the ProLine™ flagship, combining triple commercial-grade motors with app control and gyroscope-guided SmartNav 3.0™ for Dolphin’s most advanced clean.
Large-pool note: do not substitute a 50 ft residential Dolphin for a pool that genuinely requires a larger published rating. Size the cleaner to the actual pool before comparing convenience or price.
