ComparisonWybot S3 and Beatbot AquaSense 2 Pro

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 Wybot S3 AquaSense 2 Pro
Pool type
In-ground GoodDesigned for in-ground gunite pools. Dock positioning and waterline reach optimized for standard depth/slope geometry. GoodDesigned for in-ground pools with standard plumbing and return configurations.
Above-ground DependsAbove-ground pools under 10,000 gallons risk over-capacity for dock footprint. Shallow models may limit wall coverage; confirm dock fit before purchase. DependsCable length and depth sensor calibration optimized for in-ground; aboveground use possible but less reliable.
Mixed setup GoodThis robot addresses both pool types. Verify dock placement and cable routing for your setup. GoodWorks in both in-ground and aboveground pools with appropriate cable management.
Pool size
Small (< 400 sqft) GoodUnder 5,000 gallons: flagship robot and self-emptying dock exceed small-pool maintenance needs. Overkill for compact pools; mid-range cordless models more economical. GoodUnder 15,000 gallons: single run completes coverage quickly but leaves idle capacity in battery.
Medium (400 – 800) Good5,000–15,000 gallons: ideal range. 90–120 min per charge handles single-pass coverage or multi-session cleaning for heavy debris weeks. Good25,000-40,000 gallons is sweet spot: runtime covers full coverage in single autonomous session.
Large (> 800)they differ Good15,000–30,000 gallons: dock automation and cordless freedom shine. Multi-session scheduling manageable; dock self-emptying reduces operator burden. PoorOver 50,000 gallons requires multiple cycles or partial coverage per session.
Debris load
Fine (sand / silt) GoodSand and fine sediment: dock suction handles routine drainage; filter manageable with dock assist. Confirm filter mesh durability in high-silt environments. GoodSand, fine silt handled well by dual brushes and filter cartridge replacement every 4 weeks.
Leaves / large debristhey differ GoodLeaf-heavy pools: cordless operation supports frequent short runs without cable hassle. Large debris basket and dock capacity suit seasonal leaf management. DependsDual brushes prevent wrapping better than single designs; however, high leaf load requires weekly rinsing.
Algae / heavy fouling DependsAlgae bloom recovery: robot aids removal, but chemical treatment required first. Dock filter may clog after algae cleanup; manual rinse likely needed. DependsLiDAR turbidity tolerance: algae blooms above moderate levels degrade navigation accuracy significantly.
Coverage you want
Floor only GoodFloor coverage only: 3D mapping optimizes floor paths. Waterline and wall features unused; simpler maintenance profile than full-reach model. GoodPrimary focus: floor cleaning via dual brushes and autonomous path planning.
Floor + wallsthey differ GoodFloor and wall cleaning: strong suit. 36-sensor suite maps vertical surfaces; dock placement matters for wall-reach consistency. DependsClimbs walls with variable brush pressure but does not reach beyond 5-6 feet height reliably.
Floor + walls + waterlinethey differ GoodFull waterline reach: designed for this mode. Dock automation minimizes manual waterline supplementation, though mineral buildup may persist in hard-water pools. DependsWaterline follower handles cleaning but may miss tight corner crevices requiring manual attention.

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.
