The catch
Dolphin Nautilus AG
30 feet is the conservative pool limit in the technical table
Side by side
Nautilus AG is the choice when a permitted corded setup and a fixed floor-cleaning cycle fit the pool. Pooleco 10s is the choice when a much lighter dry body, app controls and cable-free use outweigh the recharge work. Walls and the waterline are covered by neither, and matching 90-minute headlines do not prove matching coverage.
Before you buy
Nautilus AG runs a 90-minute powered cycle. Pooleco 10s runs for a maximum of 90 minutes on battery and then lists a 2.5-hour charge. Those are different measures, which means neither has a proven cleaning-speed advantage. The corded Dolphin is the pick if an approved power-supply position and cable route are easy to arrange and recharge pauses would bother you. Ultenic is the pick if getting the cable out of the pool matters more. Neither cleans walls or the waterline, so that work needs another method.
Where this comes from
The Dolphin figure is a fixed program duration, so it tells you when the cycle ends. The Ultenic figure is a maximum battery duration instead. Coverage, debris and charge state can change how much gets finished in that time.
The catch
30 feet is the conservative pool limit in the technical table
The catch
Even the maximum runtime cannot prove every pool gets fully covered

Dolphin Nautilus AG and Ultenic Pooleco 10s are compared on floor-only coverage, corded versus rechargeable use, app controls and dry lifting weight.
The trade is a corded above-ground floor cycle against a much lighter cordless platform with a recharge break. Keep floor-only coverage clear throughout.
Which one fits
The options here are for floor cleaning, and neither supplied record establishes wall or waterline routes.
Dolphin is listed at about 14.62 lb, Ultenic at 3.25 kg or about 7.17 lb.
Ultenic lists a 2.5-hour charging time once its battery is depleted, while Dolphin is corded.
No app appears in Dolphin's technical table. On the Ultenic manufacturer page, app control is explicitly assigned to the 10s.
In practice
Nautilus AG runs a 90-minute powered cycle. Pooleco 10s runs for a maximum of 90 minutes on battery and then lists a 2.5-hour charge. Those are different measures, which means neither has a proven cleaning-speed advantage. The corded Dolphin is the pick if an approved power-supply position and cable route are easy to arrange and recharge pauses would bother you. Ultenic is the pick if getting the cable out of the pool matters more. Neither cleans walls or the waterline, so that work needs another method.
The Dolphin figure is a fixed program duration, so it tells you when the cycle ends. The Ultenic figure is a maximum battery duration instead. Coverage, debris and charge state can change how much gets finished in that time.
Nautilus AG publishes a dry weight of 14.619 lb. Ultenic lists 3.25 kg, which is about 7.17 lb and roughly 7.45 lb lighter. When lifting a cleaner over a low pool edge is your main constraint, that makes Pooleco the stronger candidate. The comparison ends at dry weight, since retained water, debris, reach and grip all change the real lift. Dolphin is the choice when the corded routine matters more to you and you can retrieve it safely without lifting it by the cable.
Multiply 3.25 by 2.20462 to get 7.165 lb. Take that away from 14.619 and the gap is 7.454 lb. Nothing was found on filled, wet or force-at-pool-edge measurements.
If app controls are a requirement for buying, Pooleco 10s has the app function that Nautilus AG lacks. It still needs you to retrieve it and charge it after the battery run, though. Pick the connected Ultenic if you want those controls and accept that routine, or Dolphin if you prefer a simpler corded cycle. Neither the app nor the fixed program disposes of the debris it collects or confirms that every part of the floor was cleaned.
Dolphin lists no app and a 90-minute powered floor cycle, while Ultenic lists app functions specific to the 10s and a 2.5-hour charge.

Dolphin, 99996132-PC
This corded cleaner is light and simple, and it focuses on the floor of a flat above-ground pool.

Ultenic, 10s
Very light and cordless, this floor robot pairs a roomy basket and simple app control with a 90-minute cycle.
Spec by spec
| Spec | Dolphin Nautilus AG | Ultenic Pooleco 10s | In practice |
|---|---|---|---|
| Coverage | Coverage is floor only. | Cleaning coverage is pool floor rather than walls or waterline. | Walls and waterline need another method on both. |
| 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 length and a maximum battery duration measure different things. |
| 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. | Charging follows battery use on Ultenic. |
| Dry weight | Published dry cleaner weight is 14.619 lb. | Listed dry weight is 3.25 kg, approximately 7.17 lb. | Retained water, debris and lifting geometry are left out of the published dry mass. |
Trade-offs
Change of plan
Go with Dolphin Nautilus AG. Skip the battery charge between runs. The technical table gives a conservative pool limit of 30 feet.
Go with Ultenic Pooleco 10s. You get 10s app controls and cordless operation. A maximum runtime is no proof of complete coverage in every pool.
Decision guide
Nautilus AG suits a permitted corded setup and a fixed floor-cleaning cycle. Pooleco 10s suits a much lighter dry body, app controls and cable-free use, at the price of recharge work. Neither covers walls or the waterline, and equal 90-minute headlines do not prove equal coverage.
The Nautilus AG runs a 90-minute powered cycle. The Pooleco 10s tops out at a 90-minute battery runtime and then needs a listed 2.5-hour charge. Since these are different measures, neither has a proven cleaning-speed advantage. If an approved power-supply position and cable route are easy to arrange and recharge pauses would bother you, the corded Dolphin is the one to choose. If getting the cable out of the pool matters more, choose the Ultenic. Wall and waterline cleaning are left to another method with both. A fixed program duration tells you when the Dolphin cycle ends, while the Ultenic figure is a maximum battery duration. Coverage, debris and charge state can change how much gets done in that time.
Ultenic lists 3.25 kg, which is about 7.17 lb and roughly 7.45 lb under the published 14.619 lb dry weight of Nautilus AG. That puts Pooleco ahead when the main constraint is lifting a cleaner off a low pool edge. The comparison ends at dry weight, since retained water, debris, reach and grip all change the real lift. Pick the Dolphin if the corded routine matters more to you and you can retrieve it safely without lifting by the cable. The math: 3.25 multiplied by 2.20462 gives 7.165 lb, and subtracting that from 14.619 gives 7.454 lb. No measurements of a filled or wet robot, or of the force at the pool edge, were found.
An app function that the Nautilus AG lacks comes with the Pooleco 10s, which can matter if controls are a purchase requirement. You still have to retrieve it and charge it after the battery run. Go with the connected Ultenic for those controls once you understand that routine, or with the Dolphin for a simpler corded cycle. Neither the app nor the fixed program gets rid of the collected debris or checks that every part of the floor got cleaned. Ultenic lists app functions specific to the 10s and a 2.5-hour charge. Dolphin lists no app and a 90-minute powered floor cycle.
