ComparisonAiper Scuba V3 and Maytronics Dolphin Liberty 300

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 Aiper Scuba V3 Dolphin Liberty 300
Pool type
In-groundthey differ DependsWorks for in-ground pools under 1,500 sq ft; larger pools require multiple charge cycles per week. GoodMagnetic dock and climbing capability optimized for standard in-ground installations.
Above-groundthey differ GoodOptimal for above-ground pools where dock placement on deck edges is straightforward. PoorCordless form factor and dock design not suited to above-ground frame geometries.
Mixed setup GoodDock adapter options support both pool types; placement flexibility is the main consideration. GoodStandard cordless pool cleaner fit for any standard pool type.
Pool size
Small (< 400 sqft) Good90-minute runtime covers pools under 1,400 sq ft in a single cycle without mid-session recharge. GoodBelow documented range; cordless design and dock footprint may exceed needs for pools under 8,000 gallons.
Medium (400 – 800)they differ Depends1,400-2,500 sq ft pools require two charge cycles per week; manageable but adds routine friction. GoodManufacturer-targeted range of 12,000-20,000 gallons; runtime and coverage align with medium pool cycle expectations.
Large (> 800)they differ PoorPools over 2,500 sq ft leave significant coverage gaps; multiple daily cycles become impractical. DependsPools above 25,000 gallons may require multiple charge cycles per pass; heavy debris load shortens cartridge intervals.
Debris load
Fine (sand / silt) GoodDual cartridges handle fine debris efficiently; no clogging reported in typical sediment loads. GoodFilter-cartridge design handles fine sediment; weekly rinse maintains suction for sand and silt.
Leaves / large debris DependsTree-adjacent pools require cartridge cleaning after 2-3 cycles; owners report filter clogging with heavy leaf fall. DependsCartridge clogging accelerates with heavy leaf fall; pre-skimming recommended during peak shedding season.
Algae / heavy fouling DependsOscillating brushes suppress algae growth on floor and lower walls; waterline algae requires manual treatment. DependsCleaner removes settled algae; active algae blooms require chemical treatment. Cartridge washings increase with algae frequency.
Coverage you want
Floor only GoodDedicated floor coverage with 90-minute run time; no wall or waterline reach above brush mechanism. GoodPrimary documented function with predictable floor coverage per cycle.
Floor + wallsthey differ DependsReaches lower walls below waterline; upper walls and waterline require separate skimmer or manual cleaning. GoodWall-climbing capability documented; sustained waterline reach varies by pool condition and cleaner pitch.
Floor + walls + waterlinethey differ PoorDoes not reach waterline or wall climb above brush line; full-pool coverage is not achievable with this model. DependsWaterline brush reach documented but performance on calcium buildup and algae line varies; depends on pool chemistry.

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.
