Main trade-off
Dolphin Nautilus AG
The conservative technical-table pool limit is 30 feet
Head-to-head
Choose Nautilus AG when a permitted corded setup and a fixed floor-cleaning cycle fit the pool. Choose Pooleco 10s when a much lighter dry body, app controls and cable-free use matter more than recharge work. Neither covers walls or the waterline, and equal 90-minute headlines do not prove equal coverage.
Before you choose
Nautilus AG has a 90-minute powered cycle, while Pooleco 10s has a maximum 90-minute battery runtime followed by a listed 2.5-hour charge. Those are different measures, so neither has a proven cleaning-speed advantage. Choose the corded Dolphin when an approved power-supply position and cable route are straightforward and recharge pauses are undesirable. Choose Ultenic when removing the cable from the pool is more important. Both leave wall and waterline cleaning to another method.
What this is based on
A fixed program duration describes when the Dolphin cycle ends. The Ultenic figure describes a maximum battery duration. Coverage, debris and charge state can change what is completed within that time.

Compare Dolphin Nautilus AG and Ultenic Pooleco 10s for floor-only coverage, corded versus rechargeable use, app controls and dry lifting weight.
Choose between a corded above-ground floor cycle and a much lighter cordless platform with a recharge break, while keeping floor-only coverage clear.
Winner by situation
These are floor-cleaning choices. Neither supplied record establishes wall or waterline routes.
Dolphin lists about 14.62 lb. Ultenic lists 3.25 kg, about 7.17 lb.
Dolphin is corded. Ultenic lists a 2.5-hour charging time after its battery is depleted.
Dolphin's technical table has no app. The Ultenic manufacturer page explicitly assigns app control to the 10s.
What matters in practice
Nautilus AG has a 90-minute powered cycle, while Pooleco 10s has a maximum 90-minute battery runtime followed by a listed 2.5-hour charge. Those are different measures, so neither has a proven cleaning-speed advantage. Choose the corded Dolphin when an approved power-supply position and cable route are straightforward and recharge pauses are undesirable. Choose Ultenic when removing the cable from the pool is more important. Both leave wall and waterline cleaning to another method.
A fixed program duration describes when the Dolphin cycle ends. The Ultenic figure describes a maximum battery duration. Coverage, debris and charge state can change what is completed within that time.
Ultenic's listed 3.25 kg is about 7.17 lb, roughly 7.45 lb below Nautilus AG's published 14.619 lb dry weight. That makes Pooleco the stronger candidate when lifting a cleaner from a low pool edge is the main constraint. The comparison stops at dry weight. Retained water, debris, reach and grip alter the actual lift. Choose Dolphin when the corded routine matters more and its retrieval can be handled safely without lifting by the cable.
3.25 multiplied by 2.20462 gives 7.165 lb. Subtracting from 14.619 gives 7.454 lb. No filled, wet or force-at-pool-edge measurements were found.
Pooleco 10s has the app function absent from Nautilus AG, which can matter if controls are a purchase requirement. It still needs owner retrieval and charging after the battery run. Choose the connected Ultenic for those controls with that routine understood, or Dolphin for a simpler corded cycle. Neither the app nor the fixed program disposes of collected pool debris or verifies that every part of the floor was cleaned.
Ultenic lists 10s-specific app functions and a 2.5-hour charge. Dolphin lists no app and a 90-minute powered floor cycle.

A light, simple corded cleaner that concentrates on the floor of a flat above-ground pool.

Ultenic, 10s

Meaningful differences
| What changes | Dolphin Nautilus AG | Ultenic Pooleco 10s | Why it matters |
|---|---|---|---|
| Coverage | Coverage is floor only. | Cleaning coverage is pool floor rather than walls or waterline. | Both leave walls and waterline to another method. |
| Run-duration basis | Its powered cleaning cycle is 1.5 hours. | The Pooleco 10 platform lists a 90-minute maximum battery runtime. | A fixed program and maximum battery duration are different measures. |
| Power routine | It is corded and has no app or weekly timer in the technical table. | The platform's listed charging time is 2.5 hours. | Ultenic needs charging after battery use. |
| Dry weight | Published dry cleaner weight is 14.619 lb. | Listed dry weight is 3.25 kg, approximately 7.17 lb. | Published dry mass excludes retained water, debris and lifting geometry. |
What you give up
Recommendation switch
Choose Dolphin Nautilus AG. Avoid a between-run battery charge. The conservative technical-table pool limit is 30 feet.
Choose Ultenic Pooleco 10s. Use 10s app controls and cordless operation. Maximum runtime does not prove complete coverage in every pool.
