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.
The Beatbot AquaSense 2 Ultra is cordless and rated for up to 3,444 sq ft per the current faq; the page's comparison table separately lists 3,875 sq ft. It cleans surface + floor + walls + waterline + qualifying platforms + water clarification and uses 4.0 l larger basket with 150/250 µm media + 3.7 l thinner basket with 250 µm media filtration. Runtime: Up to 5 hours floor or 10 hours surface; official pages conflict between 4.5 and 5 hours for walls/waterline.
The Dolphin T60 comes from the T-Series™ lineup. It is rated for up to 50 ft and cleans floor + walls + waterline with Multi-layer filter basket + Ultra-Fine Filter kit filtration. Its standard cycle is 2 hours.
The AquaSense 2 Ultra 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.
Start with Max-Series™ for corded value, or step up to ProLine™ for our strongest residential filtration and coverage.
For most pool owners, we recommend a corded Dolphin Max-Series™ or ProLine™ robot. Beatbot AquaSense 2 Ultra removes the cable, but it also adds charging time, finite runtime and battery care.
