We have tested both the Aiper Scuba X1 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 Aiper Scuba X1 is the lesser compromise (pulling 1.2 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 0.8–1.2 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 smaller pools that need set-and-forget cleaning on a sensible budget, also look at the Dolphin Cayman (1.5 PSI).
If you are already committed to one of these two, Aiper Scuba X1 takes the narrow edge (pulling 1.2 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 Aiper Scuba X1 and Not recommended for the Polaris Freedom. Those calls matter here: PSI is the first round, not the entire verdict.
Suction Power: 1.2 PSI vs 0.8 PSI
On our hydro manometer, the Aiper Scuba X1 measured 1.2 PSI and the Polaris Freedom measured 0.8 PSI. That gives the Aiper Scuba X1 a 0.4 PSI advantage, or about 50% 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 is easy to set up, looks polished, and beats the X1 Pro on canonical measured suction. 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 Aiper Scuba X1 uses basic mesh basket. The Polaris Freedom uses basic top-access mesh basket.
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 Aiper Scuba X1 is cordless. Simple app setup, but the connection drops underwater and charging is daily. 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 Aiper Scuba X1, our review found floor, walls, and waterline in cordless cycles. The Polaris Freedom is built for floor, walls, and waterline without a cable.
Coverage is a tie in our scoring, so choose around pool size, shape, and the surfaces you actually need cleaned.
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 Aiper Scuba X1: The least costly X1, though stronger corded cleaners remain the better use of the budget. For the Polaris Freedom: Convenient on paper, but the lowest measured suction and daily charging weaken the case.
The value edge goes to the Aiper Scuba X1.
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 Aiper Scuba X1 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:
| Category | Scuba X1 | Freedom | Premier (Buy Instead) |
|---|---|---|---|
| Our review call | Skip | Skip | Recommended |
| Measured suction | 1.2 PSI (full charge) | 0.8 PSI (full charge) | 2.2 PSI (constant corded) |
| Filtration | Basic mesh basket | Basic top-access mesh basket | Multi-Media filtration with NanoFilters, standard cartridges, and the only leaf bag in this group |
| Automation | Simple app setup, but the connection drops underwater and charging is daily | Four app modes, but every cycle still ends with retrieval and a long recharge | Weekly timer on the power supply; no daily charging |
Our #1 overall pick near this price bracket: jumps from 0.8–1.2 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 You Still Pick Between These Two
- Lesser compromise — Aiper Scuba X1: Takes the head-to-head edge (pulling 1.2 vs 0.8 PSI on our gauge). It is easy to set up, looks polished, and beats the X1 Pro on canonical measured suction.
- 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: Aiper Scuba X1 — Its 1.2 PSI, basic filter, underwater app disconnect, and recharge routine limit the value. 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. Aiper Scuba X1 edges out Polaris Freedom in a forced comparison (pulling 1.2 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.
