We have tested both the Beatbot AquaSense 2 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 only makes sense for buyers committed to Beatbot who want the line's best performance per dollar. Because neither robot is in our top recommendation tier, we also suggest cross-shopping the Dolphin Cayman (1.5 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 only if you specifically prioritize buyers committed to Beatbot who want the line's best performance per dollar — and compare both against our recommended Dolphin Cayman (1.5 PSI) before checking out.
Our calls in the full reviews are Not recommended for the Beatbot AquaSense 2 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: 1.6 PSI vs 1.5 PSI
On our hydro manometer, the Beatbot AquaSense 2 measured 1.6 PSI and the Dolphin Nautilus CC Plus measured 1.5 PSI. That gives the Beatbot AquaSense 2 a 0.1 PSI advantage, or about 7% 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. Its 1.6 PSI full-charge result matches Beatbot's flagship while costing much less. 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 uses basic fabric-style mesh basket. The Dolphin Nautilus CC Plus uses top-loading mesh cartridges without a nanofilter upgrade path.
We give the filtration edge to the Dolphin Nautilus CC Plus. 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 is cordless. App setup and cordless cycles, followed by daily retrieval and recharging. 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, our review found floor and wall cleaning with cordless deployment. The Dolphin Nautilus CC Plus is built for floor and walls in standard inground pools.
Coverage is a tie in our scoring, so choose around pool size, shape, and the surfaces you actually need cleaned.
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: The best value in its Beatbot family, but corded robots still clean with less daily work. 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.
Recommended Upgrade to Cross-Shop: Dolphin Cayman
Neither model in this comparison sits in our top recommendation tier. Before buying, compare them against the Dolphin Cayman (1.5 PSI): Closest recommended pick in the ~$1,000 tier: holds a steady 1.5 PSI from start to finish with no battery fade, supports pleated NanoFilters, and runs on a weekly timer instead of daily charging.

Which One Should You Buy?
- Head-to-head pick — Dolphin Nautilus CC Plus: Best here for buyers who value a familiar, simple Dolphin platform and find it on sale. It offers steady 1.5 PSI corded power and easy-to-reach top-loading cartridges.
- When Beatbot AquaSense 2 fits: Only for buyers committed to Beatbot who want the line's best performance per dollar. Its 1.6 PSI full-charge result matches Beatbot's flagship while costing much less.
- Know the main drawback: Dolphin Nautilus CC Plus — The mesh-only filters, limited app, and lack of waterline cleaning make it feel dated. Beatbot AquaSense 2 — The thin filter, battery fade, and daily charging keep it from being hands-off.
Final Verdict
Dolphin Nautilus CC Plus takes this head-to-head. Dolphin Nautilus CC Plus wins this head-to-head. It offers steady 1.5 PSI corded power and easy-to-reach top-loading cartridges. Beatbot AquaSense 2 remains the better fit for buyers committed to Beatbot who want the line's best performance per dollar, while the Dolphin Cayman is our top-rated step-up near this class.
