ComparisonMaytronics Dolphin Liberty 300 and Beatbot AquaSense 2

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 Dolphin Liberty 300 Beatbot AquaSense 2
Pool type
In-ground GoodMagnetic dock and climbing capability optimized for standard in-ground installations. GoodHard-sided basin enables reliable smart mapping. Foundation is stable for docking.
Above-groundthey differ PoorCordless form factor and dock design not suited to above-ground frame geometries. DependsInflatable walls and flexible geometry confuse the navigation model; coverage reduces significantly.
Mixed setup GoodStandard cordless pool cleaner fit for any standard pool type. GoodWorks on in-ground pools reliably. Evaluate above-ground case individually.
Pool size
Small (< 400 sqft) GoodBelow documented range; cordless design and dock footprint may exceed needs for pools under 8,000 gallons. GoodOvercapacity for pools under 8,000 gal; a smaller model handles similar coverage with lower cost.
Medium (400 – 800) GoodManufacturer-targeted range of 12,000-20,000 gallons; runtime and coverage align with medium pool cycle expectations. GoodRuntime and smart mapping optimized for 12,000–25,000 gal pools with moderate debris.
Large (> 800) DependsPools above 25,000 gallons may require multiple charge cycles per pass; heavy debris load shortens cartridge intervals. DependsPools over 25,000 gal require two consecutive runs or overnight charging; true set-it-and-forget-it impossible.
Debris load
Fine (sand / silt) GoodFilter-cartridge design handles fine sediment; weekly rinse maintains suction for sand and silt. GoodFilter cartridge handles sediment and algae spore load well; weekly rinse maintains flow.
Leaves / large debristhey differ DependsCartridge clogging accelerates with heavy leaf fall; pre-skimming recommended during peak shedding season. GoodHeavy leaf load forces weekly or twice-weekly filter cleaning; motor burnout risk under sustained clogging.
Algae / heavy foulingthey differ DependsCleaner removes settled algae; active algae blooms require chemical treatment. Cartridge washings increase with algae frequency. GoodWaterline brush and floor coverage address bloom prevention; autonomous cycles reduce chemical demand.
Coverage you want
Floor only GoodPrimary documented function with predictable floor coverage per cycle. GoodPrimary function; smart mapping achieves 95%+ floor coverage in open basins.
Floor + walls GoodWall-climbing capability documented; sustained waterline reach varies by pool condition and cleaner pitch. GoodWall climbing is slow and coverage gaps appear near transitions and steps; not designed for dedicated wall-scrubbing.
Floor + walls + waterlinethey differ DependsWaterline brush reach documented but performance on calcium buildup and algae line varies; depends on pool chemistry. GoodWaterline brush excels on tile and concrete; floor and line coverage are primary strengths.

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.
