Aiper removes the floating cable, but every full-capacity run depends on a charged battery. Dolphin Max-Series™ and ProLine™ deliver continuous power, immediate repeat cycles and more filtration choices.
Choose a Max-Series™ or ProLine™ Dolphin when immediate repeat cycles, no battery-care routine, model-specific filter choices and authorized-dealer support carry more weight.
Every model below is ready for another full-capacity cycle as soon as the filter is rinsed. Choose the cleaning coverage and filtration that fit your pool.

Sizing note: Pool area, maximum length, runtime and flow each tell you something different. Match the cleaner to your measured pool instead of choosing whichever headline number is largest.
The Aiper Scuba X1 Pro Max is cordless and rated for up to 3,230 sq ft / 100 ft. It cleans surface + floor + walls + waterline + elevated platforms + slopes and uses 5 l basket with 180 µm primary + 3 µm micromesh™ secondary media filtration. Runtime: Official pages conflict: 210–300 minutes floor and 600–720 minutes surface, depending on the page or table.
The Dolphin Echo comes from the Echo™ lineup. It is rated for up to 33 ft and cleans floor + walls with Fine filter basket filtration. Its standard cycle is 2 hours.
The Scuba X1 Pro Max removes the floating cable, but it adds charging time, finite runtime and battery care to the cleaning routine.
We recommend the Dolphin Sigma. It delivers corded cleaning with no recharge delay, plus it is the ProLine™ flagship, combining triple commercial-grade motors with app control and gyroscope-guided SmartNav 3.0™ for Dolphin’s most advanced clean.
Large-pool note: do not substitute a 50 ft residential Dolphin for a pool that genuinely requires a larger published rating. Size the cleaner to the actual pool before comparing convenience or price.
Start with Max-Series™ for corded value, or step up to ProLine™ for our strongest residential filtration and coverage.
For most pool owners, we recommend a corded Dolphin Max-Series™ or ProLine™ robot. Aiper Scuba X1 Pro Max removes the cable, but it also adds charging time, finite runtime and battery care.
