We have tested both the Beatbot AquaSense 2 Pro and the Dolphin Nautilus CC in real pools, measured their suction at the intake, and lived with the filtration and daily routine each one requires. This comparison brings those results together so you can see the real-world trade-offs without relying on the numbers printed on either box.

This is also a corded-versus-cordless decision: one prioritizes continuous power and scheduling, while the other removes the cable but adds charging.

The short answer: Dolphin Nautilus CC takes the head-to-head edge. It removes daily charging from the equation and covers the core floor-and-wall job. Beatbot AquaSense 2 Pro only makes sense for Beatbot buyers who specifically want the dock and extra modes. Because neither robot is in our top recommendation tier, we also suggest cross-shopping the Dolphin Sigma (2.0 PSI) before you buy.

Quick Answer

Between these two, pick the Dolphin Nautilus CC for strict budgets and light debris where basic floor and wall cleaning is enough. It is the more complete option across the measurements and ownership factors we tested.

Consider the Beatbot AquaSense 2 Pro only if you specifically prioritize Beatbot buyers who specifically want the dock and extra modes — and compare both against our recommended Dolphin Sigma (2.0 PSI) before checking out.

Our calls in the full reviews are Not recommended for the Beatbot AquaSense 2 Pro and Decent, but there are better buys for the Dolphin Nautilus CC. Those calls matter here: PSI is the first round, not the entire verdict.

Suction Power: 1.5 PSI vs 0.8 PSI

On our hydro manometer, the Beatbot AquaSense 2 Pro measured 1.5 PSI and the Dolphin Nautilus CC measured 0.8 PSI. That gives the Beatbot AquaSense 2 Pro a 0.7 PSI advantage, or about 87% more intake pressure than the lower reading.

We measure pressure directly at the intake with the same gauge and pool setup. That is different from manufacturer flow-rate claims in gallons per hour: GPH describes water movement, while PSI shows how hard the intake pulls on debris. Cordless results are recorded at full charge. Our complete pool-robot suction test explains the method and shows where both robots sit on the full board.

The number needs context. It offers a polished dock, useful modes, and a respectable 1.5 PSI at full charge. It removes daily charging from the equation and covers the core floor-and-wall job. The stronger gauge result gets this round, though intake pressure alone cannot make up for a filter that lets fine debris escape or a routine that makes you handle the robot every day.

Filtration and Debris Handling

The Beatbot AquaSense 2 Pro uses dual-layer flat mesh basket. The Dolphin Nautilus CC uses basic mesh basket with no nanofilter option.

We give the filtration edge to the Beatbot AquaSense 2 Pro. Our comparison favors fine-particle capture, usable debris capacity, easy cleaning, and whether the better filter is included rather than sold as an upgrade.

For leaves, capacity and intake design matter. For pollen, silt, and the haze that dulls otherwise clear water, the filter media matters more. A basic mesh screen can look clean after a run while still passing the smallest material back into the pool.

Automation and Daily Work

The Beatbot AquaSense 2 Pro is cordless. App features and a wireless dock, but still needs daily retrieval and charging. The Dolphin Nautilus CC is corded. Simple corded start button without a weekly timer.

That power difference changes the ownership routine. The corded robot can keep full power through the cycle and run from a schedule when its controls support one. The cordless robot removes the floating cable, but it must come out of the water to recharge. For frequent cleaning, that usually means deploying and retrieving it every day.

The automation round goes to the Dolphin Nautilus CC.

Coverage and Pool Fit

For the Beatbot AquaSense 2 Pro, our review found floor, walls, and expanded cordless cleaning modes. The Dolphin Nautilus CC is built for floor and wall cleaning for standard pools.

The Beatbot AquaSense 2 Pro wins the coverage round on the breadth of surfaces and pool situations it can handle.

This is where the runner-up can still be the smarter fit for specific pools. A compact pool does not benefit from paying for reach it cannot use, while a pool with a sun shelf, long waterline, or heavy leaf load can expose the limits of a simpler machine quickly.

Value: Performance for the Money and Time

Our value take on the Beatbot AquaSense 2 Pro: A large price jump over the base model without stronger measured suction. For the Dolphin Nautilus CC: A basic entry point, but stronger and smarter options cost only a little more.

The value edge goes to the Dolphin Nautilus CC.

Value is not the same thing as the lowest checkout price. We count cleaning power, filtration, how many surfaces the robot covers, and how often you have to retrieve or charge it. A cheaper robot that leaves you vacuuming behind it is not a bargain, and an expensive robot only earns its price when its extra capability solves a real problem in your pool.

Neither model in this comparison sits in our top recommendation tier. Before buying, compare them against the Dolphin Sigma (2.0 PSI): Closest smart-flagship alternative: boosts suction from 0.8–1.5 PSI to 2.0 PSI across a 10-inch dual intake, includes top-load pleated NanoFilters, and keeps full underwater Wi-Fi app control with a 3-year warranty.

Which One Should You Buy?

  • Head-to-head pick — Dolphin Nautilus CC: Best here for strict budgets and light debris where basic floor and wall cleaning is enough. It removes daily charging from the equation and covers the core floor-and-wall job.
  • When Beatbot AquaSense 2 Pro fits: Only for Beatbot buyers who specifically want the dock and extra modes. It offers a polished dock, useful modes, and a respectable 1.5 PSI at full charge.
  • Know the main drawback: Dolphin Nautilus CC — Its 0.8 PSI reading, basic mesh, and missing timer put it at the bottom of the corded field. Beatbot AquaSense 2 Pro — It costs far more than the base AquaSense 2 while testing slightly lower on suction.

Final Verdict

Dolphin Nautilus CC takes this head-to-head. Dolphin Nautilus CC wins this head-to-head. It removes daily charging from the equation and covers the core floor-and-wall job. Beatbot AquaSense 2 Pro remains the better fit for Beatbot buyers who specifically want the dock and extra modes, while the Dolphin Sigma is our top-rated step-up near this class.
