  • Up to 180 minutes
Why corded wins

Corded Dolphin avoids the charging routine built into every Aiper.

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.

The cordless trade-off

Scuba S1 Pro runs on a battery

  • No floating cable, but the robot must recharge after its available battery is used.
  • Runtime: Up to 180 minutes
  • Recharge time: 4 hours
Why we recommend Dolphin

Corded power keeps the next cycle ready

  • No charging delay or finite battery runtime.
  • Reusable MaxBin™, NanoFilters™ or MultiMedia™ filtration choices.
  • Authorized-dealer support and genuine replacement parts.

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.

Explore Max-Series™ or explore ProLine™.

How Scuba S1 Pro and Sigma compare

The Aiper Scuba S1 Pro is cordless and rated for up to 2,150 sq ft / 66 ft. It cleans floor + walls + waterline and uses 5 l basket with 180 µm primary + 3 µm micromesh™ secondary media filtration. Runtime: Up to 180 minutes.

The Dolphin Sigma comes from the ProLine™ lineup. It is rated for up to 50 ft and cleans floor + walls + waterline with NanoFilters™ filtration. Its standard cycle is 2.5 hours.

The easy choice: corded Dolphin

The Scuba S1 Pro removes the floating cable, but it adds charging time, finite runtime and battery care to the cleaning routine.

We recommend the Dolphin Sigma. Its corded power is ready for another cycle as soon as the filter is rinsed, and it belongs to the ProLine™.

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.

Common questions

Scuba S1 Pro vs Sigma FAQ

Is Aiper Scuba S1 Pro better than Dolphin Sigma?

What is the biggest difference between these two cleaners?

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.

No. 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 Dolphin Sigma is our Dolphin pick in this matchup. It belongs to the ProLine™ and pairs its coverage with corded power that never waits on a recharge.
