We have tested both the Aiper Scuba X1 Pro and the Clear S 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 S is our pick. It matches the Clear UV at 2.09 PSI and keeps the same filtration and coverage for less. Meanwhile, the Aiper Scuba X1 Pro carries a not recommended call in our review and is only relevant for Aiper buyers who need its specific added sensors rather than the strongest value.

Quick Answer

Buy the Clear S when its strengths match your pool. Best for: buyers who want Clear's cleaning performance at the lower price. It is the stronger choice across the measurements and ownership factors that matter in our testing.

We recommend skipping the Aiper Scuba X1 Pro for most pools (at 1.0 psi, it is the weakest x1 in our data and still requires hours of daily recharging.), unless your single overriding priority is Aiper buyers who need its specific added sensors rather than the strongest value.

Our calls in the full reviews are Not recommended for the Aiper Scuba X1 Pro and Recommended for the Clear S. Those calls matter here: PSI is the first round, not the entire verdict.

Suction Power: 1 PSI vs 2.09 PSI

On our hydro manometer, the Aiper Scuba X1 Pro measured 1 PSI and the Clear S measured 2.09 PSI. That gives the Clear S a 1.09 PSI advantage, or about 109% 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 well built, straightforward to operate, and covers the expected pool surfaces. It matches the Clear UV at 2.09 PSI and keeps the same filtration and coverage for less. 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 uses mesh basket for routine debris. The Clear S uses high-surface-area ultrafilter rated around one micron.

We give the filtration edge to the Clear S. 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 is cordless. App setup with underwater control gated behind a separate communications accessory. The Clear S 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 S.

Coverage and Pool Fit

For the Aiper Scuba X1 Pro, our review found floor, walls, and waterline in cordless cycles. The Clear S is built for floor, walls, and waterline with the same cleaning platform as the clear uv.

The Clear S 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 Aiper Scuba X1 Pro: The middle trim costs more than the base model but tested lower on suction. For the Clear S: The value-focused Clear: the same measured pull as the UV model without paying for the lamp.

The value edge goes to the Clear S.

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 S when its strengths fit your pool. Best for: buyers who want Clear's cleaning performance at the lower price. It matches the Clear UV at 2.09 PSI and keeps the same filtration and coverage for less.
  • Skip the Aiper Scuba X1 Pro for most pools: Only consider it for Aiper buyers who need its specific added sensors rather than the strongest value. At 1.0 PSI, it is the weakest X1 in our data and still requires hours of daily recharging.
  • Know the main drawback: Clear S — It does not include the UV-C feature that distinguishes the Clear UV. Aiper Scuba X1 Pro — At 1.0 PSI, it is the weakest X1 in our data and still requires hours of daily recharging.

Final Verdict

Clear S wins this comparison. Clear S wins the overall matchup. It matches the Clear UV at 2.09 PSI and keeps the same filtration and coverage for less. Aiper Scuba X1 Pro remains the better fit for Aiper buyers who need its specific added sensors rather than the strongest value.
