ComparisonBeatbot AquaSense 2 and Maytronics Dolphin Oasis Z5i

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 Oasis Z5i
Pool type
In-ground GoodHard-sided basin enables reliable smart mapping. Foundation is stable for docking. GoodDesigned for in-ground pools; dual tracks and cable length optimized for gunite and concrete walls.
Above-groundthey differ DependsInflatable walls and flexible geometry confuse the navigation model; coverage reduces significantly. PoorVinyl pool liners risk damage from track pressure; above-ground pools 5,000-12,000 gal are undersized for Z5i.
Mixed setup GoodWorks on in-ground pools reliably. Evaluate above-ground case individually. GoodStandard for this category, confirm pool type in specs before purchase.
Pool size
Small (< 400 sqft) GoodOvercapacity for pools under 8,000 gal; a smaller model handles similar coverage with lower cost. GoodZ5i targets 20,000+ gal pools; smaller pools may finish too quickly, overusing consumables.
Medium (400 – 800) GoodRuntime and smart mapping optimized for 12,000–25,000 gal pools with moderate debris. GoodOptimal for 20,000-25,000 gal in-ground pools; cable length and track endurance well-matched.
Large (> 800) DependsPools over 25,000 gal require two consecutive runs or overnight charging; true set-it-and-forget-it impossible. Depends30,000+ gal pools require cable extension (additional $120-150); single Z5i may need multiple weekly runs.
Debris load
Fine (sand / silt) GoodFilter cartridge handles sediment and algae spore load well; weekly rinse maintains flow. GoodPleated filter captures silt and algae; replace every 3-6 months depending on pool chemistry.
Leaves / large debris GoodHeavy leaf load forces weekly or twice-weekly filter cleaning; motor burnout risk under sustained clogging. GoodLarge leaves can clog filter quickly; pre-clean pool surface or reduce run frequency during fall debris season.
Algae / heavy fouling GoodWaterline brush and floor coverage address bloom prevention; autonomous cycles reduce chemical demand. GoodBristles agitate walls for bloom cleanup; pleated filter handles algae spores. Chemical treatment still required for heavy blooms.
Coverage you want
Floor only GoodPrimary function; smart mapping achieves 95%+ floor coverage in open basins. GoodZ5i excels at floor coverage but emphasizes wall-climbing; floor-only operators may prefer cheaper floor-focused models.
Floor + walls GoodWall climbing is slow and coverage gaps appear near transitions and steps; not designed for dedicated wall-scrubbing. GoodDual tracks deliver full waterline-to-floor coverage. Primary use case for Z5i premium positioning.
Floor + walls + waterlinethey differ GoodWaterline brush excels on tile and concrete; floor and line coverage are primary strengths. DependsReaches waterline but does not brush tile above waterline; manual cleanup or separate tile cleaner needed.

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.
