ComparisonBeatbot AquaSense 2 and Maytronics Dolphin EON 120d

Up to three

All robot pool cleaners. Every figure below is placed against the whole class, so a gap can be read against how much the class itself varies.

Where each one suits you.

The conditions each robot was assessed against, side by side. Rows marked in gold are where these machines genuinely differ.

Fit verdicts by condition for each robot
Condition Beatbot AquaSense 2 Dolphin EON 120d
Pool type
In-ground GoodHard-sided basin enables reliable smart mapping. Foundation is stable for docking. GoodCordless design assumes permanent dock at pool edge; in-ground installation is the primary market.
Above-groundthey differ DependsInflatable walls and flexible geometry confuse the navigation model; coverage reduces significantly. PoorCordless dock requires stable, integrated placement; above-ground pools lack power infrastructure for dock installation.
Mixed setup GoodWorks on in-ground pools reliably. Evaluate above-ground case individually. GoodIn-ground preferred; above-ground not supported per current documentation.
Pool size
Small (< 400 sqft) GoodOvercapacity for pools under 8,000 gal; a smaller model handles similar coverage with lower cost. GoodMSRP $1,199 targets larger pools; smaller pools may find similar coverage in lower-tier cordless models.
Medium (400 – 800) GoodRuntime and smart mapping optimized for 12,000–25,000 gal pools with moderate debris. Good12,000–25,000 gallons aligns with manufacturer documentation and DebrisLock design specifications.
Large (> 800)they differ DependsPools over 25,000 gal require two consecutive runs or overnight charging; true set-it-and-forget-it impossible. GoodSmart mapping supports multi-session coverage for pools over 25,000 gallons; runtime per cycle undocumented.
Debris load
Fine (sand / silt) GoodFilter cartridge handles sediment and algae spore load well; weekly rinse maintains flow. GoodStandard filters and backwash handle algae and fine particles; DebrisLock not primarily designed for fine debris.
Leaves / large debris GoodHeavy leaf load forces weekly or twice-weekly filter cleaning; motor burnout risk under sustained clogging. GoodDebrisLock backwash system engineered specifically for leaf and organic debris volume without filter clogging.
Algae / heavy foulingthey differ GoodWaterline brush and floor coverage address bloom prevention; autonomous cycles reduce chemical demand. DependsAlgae requires chemical treatment and brush scrubbing; Dolphin handles removal but does not address root cause.
Coverage you want
Floor only GoodPrimary function; smart mapping achieves 95%+ floor coverage in open basins. GoodSmart mapping documented for floor-only coverage patterns; baseline autonomy performance.
Floor + walls GoodWall climbing is slow and coverage gaps appear near transitions and steps; not designed for dedicated wall-scrubbing. GoodEON 120d reaches walls per manufacturer specs; waterline and tanning-ledge coverage included.
Floor + walls + waterlinethey differ GoodWaterline brush excels on tile and concrete; floor and line coverage are primary strengths. DependsWaterline reach confirmed; full waterline scrub cadence depends on smart-map programming and documented test cycles.

A robot being poor for a condition is a fact about fit, not a fault. “Depends” means the record names a limit worth reading, not that the answer is unknown.
