We have tested both the Beatbot AquaSense 2 Pro and the Dolphin Nautilus CC Plus 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 Plus takes the head-to-head edge. It offers steady 1.5 PSI corded power and easy-to-reach top-loading cartridges. 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 Plus for buyers who value a familiar, simple Dolphin platform and find it on sale. 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 Plus. Those calls matter here: PSI is the first round, not the entire verdict.

Suction Power: 1.5 PSI vs 1.5 PSI

On our hydro manometer, both robots measured 1.5 PSI. Raw suction is a tie, so filtration, coverage, automation, and value decide this matchup.

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 offers steady 1.5 PSI corded power and easy-to-reach top-loading cartridges. 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 Plus uses top-loading mesh cartridges without a nanofilter upgrade path.

Filtration is effectively even in our scoring. The better choice depends on the debris in your pool and which basket or cartridge design you prefer to rinse.

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 Plus is corded. Limited app controls; no full scheduling or steering suite.

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 Plus.

Coverage and Pool Fit

For the Beatbot AquaSense 2 Pro, our review found floor, walls, and expanded cordless cleaning modes. The Dolphin Nautilus CC Plus is built for floor and walls in standard inground 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 Plus: Reliable, but newer Dolphins offer better automation or filtration for similar money.

The value edge goes to the Dolphin Nautilus CC Plus.

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 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.
