Why corded wins
Corded Dolphin keeps pool cleaning simpler than a battery-powered Beatbot.
Beatbot adds smart features, but it also adds charging, finite runtime and battery care. Dolphin Max-Series™ and ProLine™ keep the routine simple with continuous corded power and reusable filtration.
AquaSense 2 runs on a battery
- No floating cable, but the robot must recharge after its available battery is used.
- Runtime: Up to 4 hours floor or 3.5 hours walls/waterline
- Recharge time: About 4 hours
Corded power keeps the next cycle ready
- No charging delay or finite battery runtime.
- Reusable MaxBin™, NanoFilters™ or MultiMedia™ filtration choices.
- Authorized-dealer support and genuine replacement parts.
Choose a Max-Series™ or ProLine™ Dolphin when immediate repeat cycles, simpler corded operation, model-specific filtration and Maytronics' authorized-dealer network matter more.

Sizing note: Beatbot uses pool area while many Dolphins use maximum pool length. Match each rating to your measured pool instead of trying to convert one into the other.
How AquaSense 2 and Premier compare
The Beatbot AquaSense 2 is cordless and rated for up to 3,230 sq ft. It cleans floor + walls + waterline and uses 2 l, 150 µm filter basket filtration. Runtime: Up to 4 hours floor or 3.5 hours walls/waterline.
The Dolphin Premier comes from the ProLine™ lineup. It is rated for up to 50 ft and cleans floor + walls + waterline with MultiMedia™ + NanoFilters™ filtration. Its standard cycle is 3 hours.
The easy choice: corded Dolphin
The AquaSense 2 removes the floating cable, but it adds charging time, finite runtime and battery care to the cleaning routine.
We recommend the Dolphin Premier. Its corded power is ready for another cycle as soon as the filter is rinsed, and it belongs to the ProLine™.
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.
