The catch
Beatbot AquaSense
The 3.5-hour maximum belongs to floor mode alone
Side by side
The original AquaSense A100 is the choice for cordless floor, wall and waterline cleaning, provided retrieval and charging fit your routine. Dolphin Nautilus CC is the choice for a powered two-hour floor-and-wall cycle in a pool within its 33-foot limit. The 3.5-hour maximum for AquaSense is a floor-cleaning figure, and this original model does not take on the surface skimming of AquaSense Plus.
Before you buy
Nautilus CC specifies a two-hour cycle, and AquaSense advertises up to 3.5 hours in floor cleaning. That 90-minute numerical difference does not prove AquaSense spends the extra time on walls or the waterline. AquaSense is the pick for its documented coverage and cordless setup, as long as you have a realistic charging plan. Dolphin is the pick when its powered floor-and-wall program suits a pool within 33 feet and battery endurance is not a useful advantage.
Where this comes from
Convert 3.5 hours to 210 minutes, then 210 minus 120 leaves 90. The two durations rest on different operating bases, so the subtraction is no cleaning-performance score.
The catch
The 3.5-hour maximum belongs to floor mode alone
The catch
Waterline cleaning is not claimed

The original Beatbot AquaSense A100 and Dolphin Nautilus CC are compared on waterline coverage, retrieval, charging and mode-specific runtime.
Which one fits
Nautilus CC does not document it, but AquaSense A100 does.
CC covers floor and walls, and the original AquaSense A100 lacks the skimming function of the Plus.
The current limit for Dolphin is 33 feet. For AquaSense, check the full size and shape requirements.
Dolphin is powered through its cable, while AquaSense needs its charging dock.
In practice
Nautilus CC specifies a two-hour cycle, and AquaSense advertises up to 3.5 hours in floor cleaning. That 90-minute numerical difference does not prove AquaSense spends the extra time on walls or the waterline. AquaSense is the pick for its documented coverage and cordless setup, as long as you have a realistic charging plan. Dolphin is the pick when its powered floor-and-wall program suits a pool within 33 feet and battery endurance is not a useful advantage.
Convert 3.5 hours to 210 minutes, then 210 minus 120 leaves 90. The two durations rest on different operating bases, so the subtraction is no cleaning-performance score.
AquaSense can head back toward its starting area and park at the waterline, which may put the pickup spot within easier reach. Someone still has to take it out, clean the filter and use the charging dock. Because Dolphin is powered through a connection, charging drops out of that routine, though removal and care are still needed. AquaSense is the choice if cable-free operation is worth those steps. Dolphin is the choice if avoiding charging is the stronger constraint.
Positioning itself automatically is not the same as lifting, docking or emptying automatically. For these two cleaners, no ready-to-lift wet-weight comparison was established.
Submerged surfaces are what the original AquaSense A100 cleans. It lacks the floating-surface skimming function of the Plus model, and Nautilus CC likewise documents floor and walls instead of that role. When floating leaves are the main problem, do not pick either on the assumption that it skims the surface. Between these exact models, AquaSense is the choice for waterline cleaning and Dolphin for its powered routine, and the surface-debris task needs its own plan.
Keeping the original A100 and AquaSense Plus apart as different configurations prevents you from borrowing a feature from another product generation or package.

Beatbot, A100
This cordless cleaner runs for a long time, has strong published flow and covers the floor, walls and waterline.

Dolphin, 99996113-USB
This compact corded Dolphin climbs walls and still stays light and uncomplicated.
Spec by spec
| Spec | Beatbot AquaSense | Dolphin Nautilus CC | In practice |
|---|---|---|---|
| Coverage | The original AquaSense A100 cleans floors, walls and waterline. | It cleans the floor and walls without a waterline-cleaning claim. | The waterline role that this Dolphin lacks comes with AquaSense. |
| Duration basis | Its maximum 3.5-hour runtime is specified for floor cleaning. | The standard cycle lasts two hours. | A fixed two-hour cycle is not the same as maximum floor-mode endurance. |
| Power arrangement | Battery capacity is 6,700 mAh. | It is corded. | A cordless cleaner does not charge itself just because it has battery capacity. |
| After the run | It uses a charging dock and does not include the Plus model's surface-skimming function. | The technical table specifies no weekly timer. | Having a charging dock and lacking a weekly timer lead to different ownership routines. |
Trade-offs
Change of plan
Go with Beatbot AquaSense. Return-to-start and waterline parking are there for retrieval. The 3.5-hour maximum applies to floor mode specifically.
Go with Dolphin Nautilus CC. A documented two-hour cycle works in a pool up to 33 feet. Waterline cleaning is not claimed.
Decision guide
Original AquaSense A100 suits cordless floor, wall and waterline cleaning when retrieval and charging fit your routine. Dolphin Nautilus CC suits a powered two-hour floor-and-wall cycle in a pool within its 33-foot limit. AquaSense's 3.5-hour maximum is a floor-cleaning figure, and this original model has no AquaSense Plus surface skimming.
AquaSense advertises up to 3.5 hours of floor cleaning, and Nautilus CC specifies a two-hour cycle. That 90-minute difference on paper does not prove AquaSense spends the extra time on walls or the waterline. Pick AquaSense for its documented coverage and cordless setup, as long as you have a realistic charging plan. Pick Dolphin if its powered floor-and-wall program fits a pool within 33 feet and battery endurance gives you no useful advantage. 3.5 hours is 210 minutes, and 210 minus 120 is 90. Because the two durations rest on different operating bases, the subtraction is not a cleaning-performance score.
AquaSense can head back toward its starting area and park at the waterline, which may make the pickup spot easier to reach. Someone still has to take it out, clean the filter and use the charging dock. The powered connection on the Dolphin takes charging out of that routine, though removal and care are still needed. Go with AquaSense if cable-free operation is worth those steps, and with Dolphin if avoiding charging is the stronger constraint. Automatic positioning is not the same as automatic lifting, docking or emptying. No ready-to-lift wet-weight comparison was established for these two cleaners.
The original AquaSense A100 cleans submerged surfaces but lacks the floating-surface skimming function of the Plus model. Nautilus CC likewise documents floor and walls only. If floating leaves are your main problem, do not pick either one on the assumption that it skims the surface. Between these exact models, take AquaSense for waterline cleaning or Dolphin for its powered routine, and plan the surface-debris task separately. The original A100 and AquaSense Plus are different configurations, and keeping them apart avoids importing a feature from another product generation or package.
