Head-to-head
Beatbot AquaSense A100 vs Dolphin Nautilus CC: AquaSense adds cordless waterline work, not surface skimming
The short answer
Choose original AquaSense A100 for cordless floor, wall and waterline cleaning when retrieval and charging fit your routine. Choose Dolphin Nautilus CC for 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. This original model does not inherit AquaSense Plus surface skimming.
Before you choose
The reasoning and the trade-offs
The extra 90 minutes is a mode-specific number
AquaSense advertises up to 3.5 hours in floor cleaning, while Nautilus CC specifies a two-hour cycle. The 90-minute numerical difference does not prove AquaSense spends that extra time on walls or the waterline. Choose AquaSense for its documented coverage and cordless setup, with a realistic charging plan. Choose Dolphin when its powered floor-and-wall program fits a pool within 33 feet and battery endurance is not a useful advantage.
What this is based on
3.5 hours is 210 minutes, and 210 minus 120 is 90. The two durations describe different operating bases, so the subtraction is not a cleaning-performance score.

What matters in practice
The differences that matter
The extra 90 minutes is a mode-specific number
AquaSense advertises up to 3.5 hours in floor cleaning, while Nautilus CC specifies a two-hour cycle. The 90-minute numerical difference does not prove AquaSense spends that extra time on walls or the waterline. Choose AquaSense for its documented coverage and cordless setup, with a realistic charging plan. Choose Dolphin when its powered floor-and-wall program fits a pool within 33 feet and battery endurance is not a useful advantage.
How we reached this conclusion
3.5 hours is 210 minutes, and 210 minus 120 is 90. The two durations describe different operating bases, so the subtraction is not a cleaning-performance score.
Waterline parking helps retrieval without completing it
AquaSense can return toward its starting area and park at the waterline, which may make the pickup location easier to reach. It still needs an owner to remove it, clean the filter and use the charging dock. Dolphin's powered connection removes charging from that routine, though removal and care remain necessary. Choose AquaSense when cable-free operation is worth those steps. Choose Dolphin when avoiding charging is the stronger constraint.
How we reached this conclusion
Automatic positioning is distinct from automatic lifting, docking or emptying. No ready-to-lift wet-weight comparison was established for these two cleaners.
Surface skimming requires another product identity
The original AquaSense A100 cleans submerged surfaces but does not include the Plus model's floating-surface skimming function. Nautilus CC likewise documents floor and walls rather than that role. If floating leaves are the main problem, neither should be selected on a surface-skimmer assumption. Between these exact models, choose AquaSense for waterline cleaning or Dolphin for its powered routine, and plan the surface-debris task separately.
How we reached this conclusion
The original A100 and AquaSense Plus are different configurations. Preserving that distinction avoids importing a feature from another product generation or package.

Meaningful differences
What changes the fit
| What changes | Beatbot AquaSense | Dolphin Nautilus CC | Why it matters |
|---|---|---|---|
| Coverage | The original AquaSense A100 cleans floors, walls and waterline. | It cleans the floor and walls without a waterline-cleaning claim. | AquaSense adds the waterline role missing from this Dolphin. |
| Duration basis | Its maximum 3.5-hour runtime is specified for floor cleaning. | The standard cycle lasts two hours. | Maximum floor-mode endurance is different from a fixed two-hour cycle. |
| Power arrangement | Battery capacity is 6,700 mAh. | It is corded. | Battery capacity does not make the cordless cleaner self-charging. |
| 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. | A charging dock and the absence of a weekly timer create different ownership routines. |
What you give up
Every choice has a cost
If you choose Beatbot AquaSense
- The owner still retrieves and charges the cleaner
If you choose Dolphin Nautilus CC
- No weekly timer in the exact technical table
Recommendation switch
The decision flips if...
Add documented waterline cleaning without a power cable
Choose Beatbot AquaSense. Use return-to-start and waterline parking for retrieval. The 3.5-hour maximum is floor-mode-specific.
Avoid a battery-charging step
Choose Dolphin Nautilus CC. Use a documented two-hour cycle in a pool up to 33 feet. No waterline-cleaning claim.
What matters in practice
Before you choose
What this comparison cannot tell you
- Maximum floor-mode endurance is not a whole-pool cleaning-time guarantee.
