Beatbot AquaSense 2 vs Dolphin Premium 20
See how these two robots compare—and why the Dolphin Quantum Pro is the easy choice for corded cleaning with no battery downtime.
Dolphin Premium 20
Premium™
2 years manufacturer warranty
- Corded — no recharge time

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.

How AquaSense 2 and Premium 20 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 Premium 20 comes from the Premium™ lineup. It is rated for up to 33 ft and cleans floor + walls with Fine filter basket filtration. Its standard cycle is 2 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 Quantum Pro. It delivers corded cleaning with no recharge delay, plus it bridges both flagship lineups with app control, an XXL MaxBin™, NanoFilters™ and cleaning from the floor and steps through the waterline.
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.
