We have tested both the Beatbot AquaSense 2 Ultra and the Polaris Freedom 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.

Both use cordless power, so this matchup turns on measured pull, filtration, coverage, automation, and value.

The short answer: we recommend skipping both. Neither robot earned a buy call in our pool testing. If you want our closest recommended alternative for what you are shopping here, look at the Dolphin Premier (2.2 PSI). If you are strictly choosing between these two models, the Beatbot AquaSense 2 Ultra is the lesser compromise (pulling 1.6 vs 0.8 PSI on our gauge).

Quick Answer

Our honest call is to skip both robots and buy the Dolphin Premier instead. Our #1 overall pick near this price bracket: jumps from 0.8–1.6 PSI to a leaderboard-leading 2.2 PSI, includes Multi-Media NanoFilters plus a leaf bag, and automates daily cleaning on a weekly timer. If your priorities lean more toward buyers who want near-Premier power with full app control, also look at the Dolphin Sigma (2.0 PSI).

If you are already committed to one of these two, Beatbot AquaSense 2 Ultra takes the narrow edge (pulling 1.6 vs 0.8 PSI on our gauge). The Polaris Freedom is only worth considering for Polaris loyalists whose first priority is avoiding a cord.

Our calls in the full reviews are Not recommended for the Beatbot AquaSense 2 Ultra and Not recommended for the Polaris Freedom. Those calls matter here: PSI is the first round, not the entire verdict.

Suction Power: 1.6 PSI vs 0.8 PSI

On our hydro manometer, the Beatbot AquaSense 2 Ultra measured 1.6 PSI and the Polaris Freedom measured 0.8 PSI. That gives the Beatbot AquaSense 2 Ultra a 0.8 PSI advantage, or about 100% 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 packs the widest Beatbot feature list and posts 1.6 PSI on a full charge. It covers the main pool surfaces and its filter basket is easy to reach and rinse. 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 Ultra uses small dual-layer mesh basket. The Polaris Freedom uses basic top-access mesh basket.

We give the filtration edge to the Beatbot AquaSense 2 Ultra. 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 Ultra is cordless. Many app features, but underwater connection and daily charging remain limitations. The Polaris Freedom is cordless. Four app modes, but every cycle still ends with retrieval and a long recharge.

Because both are cordless, neither is truly set-and-forget. Compare runtime and app features, but plan on retrieving, charging, and redeploying either robot between cycles.

We score automation as a tie.

Coverage and Pool Fit

For the Beatbot AquaSense 2 Ultra, our review found floor, walls, waterline, and surface-skimming modes. The Polaris Freedom is built for floor, walls, and waterline without a cable.

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

Surface coverage on a spec sheet only goes so far if suction fades or the filter misses fine dust. Match the robot’s reach to your pool size, and weigh how often you are willing to handle the unit to keep those surfaces clean.

Value: Performance for the Money and Time

Our value take on the Beatbot AquaSense 2 Ultra: The most expensive Beatbot while matching the base model's canonical full-charge PSI. For the Polaris Freedom: Convenient on paper, but the lowest measured suction and daily charging weaken the case.

We score value evenly. In that case, your pool fit should break the tie.

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.

What to Buy Instead

Because both the Beatbot AquaSense 2 Ultra and Polaris Freedom earned a skip in our testing, compare them directly against any pick from our Best Robotic Pool Cleaners of 2026 list below — starting with our closest match, the Dolphin Premier:

If You Still Pick Between These Two

  • Lesser compromise — Beatbot AquaSense 2 Ultra: Takes the head-to-head edge (pulling 1.6 vs 0.8 PSI on our gauge). It packs the widest Beatbot feature list and posts 1.6 PSI on a full charge.
  • Narrow case for Polaris Freedom: Only relevant for Polaris loyalists whose first priority is avoiding a cord. It covers the main pool surfaces and its filter basket is easy to reach and rinse.
  • Why we skip both overall: Beatbot AquaSense 2 Ultra — Its tiny basket, daily battery routine, and flagship price are difficult to justify. Polaris Freedom — Its 0.8 PSI is the lowest cordless reading in our canonical set, followed by a four-to-six-hour recharge.

Final Verdict

Skip both — buy the Dolphin Premier instead. Beatbot AquaSense 2 Ultra edges out Polaris Freedom in a forced comparison (pulling 1.6 vs 0.8 PSI on our gauge), but both carry a Not recommended call in our reviews. The Dolphin Premier (2.2 PSI) is the closest recommended robot to buy instead.
