Aiper Scuba S1 Pro vs Dolphin W 20
See how these two robots compare—and why the Dolphin Quantum Pro is the easy choice for corded cleaning with no battery downtime.

3 years manufacturer warranty
- Corded — no recharge time
- Up to 65 ft
- Floor
- Filter bag
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.
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
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.

How Scuba S1 Pro and W 20 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 W 20 comes from the Wave™ Commercial lineup. It is rated for up to 65 ft and cleans floor with Filter bag filtration. Its standard cycle is 3 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 Quantum Pro. It delivers corded cleaning with no recharge delay, plus it bridges both flagship lineups with app control, an XXL MaxBin™, NanoFilters™ and cleaning from the floor and steps through the waterline.
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.
