ComparisonAiper Seagull Plus and Ecovacs Ultramarine P1

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 Seagull Plus Ecovacs Ultramarine P1
Pool type
In-ground GoodDesigned for in-ground gunite and concrete pools; cordless wheels optimized for hard surfaces. GoodBoth reviewers used it in in-ground pools, including a large pebblecrete pool with sloped sections.
Above-groundthey differ PoorCordless robots not suited for vinyl liners or soft pool bottoms; above-ground pools undersized for Seagull Plus price and complexity. DependsNo above-ground test has been published, and the manual needs at least 0.5 m of water depth.
Mixed setupthey differ GoodStandard for this category, confirm pool construction before purchase. DependsOnly in-ground use is documented, so a mixed setup that needs both is unconfirmed.
Pool size
Small (< 400 sqft) Good90-minute runtime covers small pools easily; unit may finish before you reach dock, wasting battery charge efficiency. Floor-only model recommended for compact layouts. GoodRated for 180 m² of floor per charge, well above a small pool's needs.
Medium (400 – 800) GoodOptimal for 12,000-20,000 gal in-ground pools; 90-minute runtime aligns with average floor coverage. GoodDigital Reviews cleaned a large bean-shaped pool in about two hours on one charge.
Large (> 800) DependsPools 25,000+ gal require two runs; battery swap between cycles adds 2-3 minutes. Purchase second battery if running back-to-back sessions desired. DependsCoverage is rated at 180 m² per charge, and a recharge takes about 4 hours.
Debris load
Fine (sand / silt) GoodSuction captures silt and algae spores. Cartridge replacement every 3-4 months maintains performance. GoodThe 3-micron inner filter captures silt and fine particles, though EFTM found it slow to rinse clean.
Leaves / large debristhey differ DependsLarge leaves clog intake quickly; pre-clean pool surface during fall. Run frequency limited to 1-2 times weekly in heavy debris season. GoodThe 180-micron basket takes leaves and twigs; remove the fine filter for heavy debris, per the manual.
Algae / heavy fouling DependsSuction-only design handles algae dust but not thick algae mats. Chemical treatment required first; robot captures freed particles. DependsThe manual says the 3-micron filter catches certain algae; no reviewer tested an algae bloom.
Coverage you want
Floor only GoodFloor-only focus. Standard for cordless models; suits pools without wall or waterline debris emphasis. GoodBoth reviewers report floors consistently cleaned across repeated runs.
Floor + wallsthey differ PoorNo wall climbing capability. Compare to wall-climbing corded models if wall and waterline coverage required. DependsDigital Reviews found it detached from some wall sections and drifted down before repositioning.
Floor + walls + waterlinethey differ PoorFloor-only design incompatible with waterline cleaning. Separate tile or waterline cleaner required for line coverage. DependsWall mode reached the waterline in some sections of Digital Reviews' pool but not all.

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.
