We have tested both the Clear UV and the Dolphin Premier 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 corded power, so this matchup turns on measured pull, filtration, coverage, automation, and value.
The short answer: Dolphin Premier is our pick. It leads our gauge at 2.2 PSI and handles leaves, fine debris, and scheduled cleaning without battery work. Clear UV still has a clear case: it is the better fit for buyers who want elite suction plus the added UV-C feature.
Quick Answer
Buy the Dolphin Premier when its strengths match your pool. Best for: leafy pools and owners who want the strongest pull we have measured. It is the stronger choice across the measurements and ownership factors that matter in our testing.
Choose the Clear UV instead when its narrower advantages matter more to you. 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.
Our calls in the full reviews are Recommended for the Clear UV and Recommended for the Dolphin Premier. Those calls matter here: PSI is the first round, not the entire verdict.
Suction Power: 2.09 PSI vs 2.2 PSI
On our hydro manometer, the Clear UV measured 2.09 PSI and the Dolphin Premier measured 2.2 PSI. That gives the Dolphin Premier a 0.11 PSI advantage, or about 5% 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. At 2.09 PSI, it is the second-strongest robot in our canonical test data and adds UV-C treatment. It leads our gauge at 2.2 PSI and handles leaves, fine debris, and scheduled cleaning without battery work. 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 Clear UV uses high-surface-area ultrafilter rated around one micron. The Dolphin Premier uses multi-media filtration with nanofilters, standard cartridges, and the only leaf bag in this group.
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 Clear UV is corded. App and power-supply controls with scheduled corded cleaning. The Dolphin Premier is corded. Weekly timer on the power supply; no daily charging.
Because both are corded, neither needs a recharge. The meaningful question is how much scheduling and remote control each power supply or app provides.
We score automation as a tie.
Coverage and Pool Fit
For the Clear UV, our review found floor, walls, and waterline, plus a built-in uv-c surface-treatment pass. The Dolphin Premier is built for floor, walls, and waterline with a 9.5-inch dual intake path.
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 Clear UV: Top-tier cleaning with UV as an extra feature rather than a substitute for suction. For the Dolphin Premier: Premium-priced, but our strongest measured cleaner and the most versatile for mixed debris.
The value edge goes to the Dolphin Premier.
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 Dolphin Premier when its strengths fit your pool. Best for: leafy pools and owners who want the strongest pull we have measured. It leads our gauge at 2.2 PSI and handles leaves, fine debris, and scheduled cleaning without battery work.
- Choose the Clear UV instead when its specific trade-off fits better. 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.
- Know the main drawback: Dolphin Premier — It has no smartphone app, so controls stay on the power supply. Clear UV — The UV lamp is a consumable and raises the price over the otherwise similar Clear S.
Final Verdict
Dolphin Premier wins this comparison. Dolphin Premier wins the overall matchup. It leads our gauge at 2.2 PSI and handles leaves, fine debris, and scheduled cleaning without battery work. Clear UV remains the better fit for buyers who want elite suction plus the added UV-C feature.
