We have tested both the Aiper Scuba X1 Pro Max and the Clear UV 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: Clear UV is our pick. At 2.09 PSI, it is the second-strongest robot in our canonical test data and adds UV-C treatment. Meanwhile, the Aiper Scuba X1 Pro Max carries a not recommended call in our review and is only relevant for Aiper loyalists who want the broadest X1 feature set.
Quick Answer
Buy the Clear UV when its strengths match your pool. Best for: buyers who want elite suction plus the added UV-C feature. It is the stronger choice across the measurements and ownership factors that matter in our testing.
We recommend skipping the Aiper Scuba X1 Pro Max for most pools (its 1.3 psi, long recharge, heavy body, and paid connectivity add-on undercut the flagship price.), unless your single overriding priority is Aiper loyalists who want the broadest X1 feature set.
Our calls in the full reviews are Not recommended for the Aiper Scuba X1 Pro Max and Recommended for the Clear UV. Those calls matter here: PSI is the first round, not the entire verdict.
Suction Power: 1.3 PSI vs 2.09 PSI
On our hydro manometer, the Aiper Scuba X1 Pro Max measured 1.3 PSI and the Clear UV measured 2.09 PSI. That gives the Clear UV a 0.79 PSI advantage, or about 61% 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 the strongest X1 model on our gauge and adds broad coverage with an easy top-load basket. At 2.09 PSI, it is the second-strongest robot in our canonical test data and adds UV-C treatment. 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 Pro Max uses top-loading mesh basket with a fabric-style fine layer. The Clear UV uses high-surface-area ultrafilter rated around one micron.
We give the filtration edge to the Clear UV. 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 Aiper Scuba X1 Pro Max is cordless. App setup, but underwater control requires the separate HydroComm accessory. The Clear UV is corded. App and power-supply controls with scheduled corded cleaning.
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 Clear UV.
Coverage and Pool Fit
For the Aiper Scuba X1 Pro Max, our review found floor, walls, waterline, and surface-skimming modes. The Clear UV is built for floor, walls, and waterline, plus a built-in uv-c surface-treatment pass.
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 Aiper Scuba X1 Pro Max: Feature-rich and attractive, but expensive for its measured cleaning performance. For the Clear UV: Top-tier cleaning with UV as an extra feature rather than a substitute for suction.
The value edge goes to the Clear UV.
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.
Which One Should You Buy?
- Buy the Clear UV when its strengths fit your pool. Best for: buyers who want elite suction plus the added UV-C feature. At 2.09 PSI, it is the second-strongest robot in our canonical test data and adds UV-C treatment.
- Skip the Aiper Scuba X1 Pro Max for most pools: Only consider it for Aiper loyalists who want the broadest X1 feature set. Its 1.3 PSI, long recharge, heavy body, and paid connectivity add-on undercut the flagship price.
- Know the main drawback: Clear UV — The UV lamp is a consumable and raises the price over the otherwise similar Clear S. Aiper Scuba X1 Pro Max — Its 1.3 PSI, long recharge, heavy body, and paid connectivity add-on undercut the flagship price.
Final Verdict
Clear UV wins this comparison. Clear UV wins the overall matchup. At 2.09 PSI, it is the second-strongest robot in our canonical test data and adds UV-C treatment. Aiper Scuba X1 Pro Max remains the better fit for Aiper loyalists who want the broadest X1 feature set.
