Clear UV vs. Dolphin Premier: The Filter Decides It

I ran the Dolphin Premier in my kidney-shaped pool for more than four years. It was still working when I replaced it with the Clear UV, which I had then used nearly every day for three months.

That history makes this an ownership comparison, but not an equal-duration durability test. I know how the Premier ages. I know how the Clear handles daily debris, fine dust, walls, and the waterline. I cannot yet say the Clear will match four years of service.

For most routine weeks, I would buy the Clear UV. Its basket lifts through the top, its included pleated panels caught the fine material in my pool, and its app gives me a more useful schedule.

I would still buy the Premier for a pool buried in leaves. The fabric bag supplied with my unit handled bulky fall debris better than a pleated basket, and the Premier gives you that option without giving up waterline coverage.

That is the deciding tradeoff: easier weekly handling and connected controls from the Clear, or the Premier's season-specific filter choices, especially its leaf bag.

What the Published Specifications Do and Do Not Tell You

Those flow figures come from the manufacturers. I did not measure either pump on a bench, and GPH alone does not tell you how much dirt a robot removes. Brush contact, filter loading, pool shape, cable placement, and the kind of debris all affect a cycle.

The same caution applies to navigation names. A robot can have a branded scanning system and still miss a drain, step, corner, or narrow strip. I judge coverage by what remained in my pool, not by the name on the box.

The Clear Is Easier After Every Ordinary Cycle

Pool robots create a small job after they finish. You pull up a wet machine, carry it clear of the coping, remove the filter, dump the load, and rinse the media. The design of that filter matters more after the twentieth cycle than it does in a product photo.

The Clear's basket comes straight out through the top. I can leave the robot upright, lift one container, and see what it collected. The pleated panels need a careful spray when fine silt gets deep between the folds, but access is simple.

The Premier puts its media behind a bottom plate. I had to drain the robot, set it on the deck, turn the 20-pound body over, release the latches, and remove the assembly. None of those steps is difficult. Repeating them for four years made me appreciate the Clear's top opening.

The Clear is seven pounds heavier on paper, so it is not the easier robot to lift. Pause at the waterline and let it drain before bringing it over the coping. Never use the floating cable as a lifting strap. Once both machines are on the deck, however, the Clear is the quicker one to empty.

Leaf Season Changes the Answer

My Premier's best filter was the oversized fabric bag. During Texas leaf drop, it carried whole oak leaves, pine needles, twigs, and acorns that would quickly occupy a rigid cartridge. The load shown above came from one cycle.

That experience is specific to the package I owned. Maytronics' current U.S. page for model 99996339-SPL identifies an additional fine filter kit, while specialty dealers advertise packages with the oversized leaf bag and pleated media. Do not assume every box at every price contains all three. Get the included-media list in writing.

My Clear also picked up oak leaves, pine needles, pebbles, and acorns, and its basket finished heavy cycles without an obvious loss of pull. It is not poor with leaves. Its drawback appears when bulky debris and fine material pack into the same pleated basket. Dumping the leaves is quick; spraying the folds clean is not.

For a screened pool or a yard with a moderate amount of debris, I would accept that rinse and take the top access. For several weeks of dense leaf fall, I would rather fit the Premier's bag and empty a larger, less fussy container.

Fine Debris Favors the Clear Out of the Box

Clear lists two filter ratings in its manual: 1 micron for the fine media and 180 microns for the coarse media. Those are manufacturer ratings, not measurements I independently confirmed.

What I can support from use is narrower. After Clear cycles, I found fine material held in the pleats and saw less dust settle back onto the floor. My water took on the clean, polished appearance I associate with good pleated filtration.

The Premier can do the same kind of work with its pleated panels. Mine came out coated in spring pollen and silt. The advantage is choice: I could change from the leaf bag to fine media as the season changed. The disadvantage is more parts and bottom access.

Do not buy either robot expecting one filter to be ideal for every load. Mesh or a bag is easier with large debris. Pleats catch finer material but take longer to wash. The Clear makes fine media its normal setup; the Premier makes media selection part of ownership.

Both Worked at My Waterline, but Neither Solved Shallow Areas

The Premier climbed my walls and moved sideways at the surface. I adjusted its floating handle to help it hold the intended orientation, and it maintained the tile line through years of use.

The Clear also climbed my walls and scrubbed at the waterline during my first three months. Clear attributes that performance partly to its 8,500-plus-GPH pump system. I observed the result, not the cause, so I would not reduce wall behavior to one flow number.

Neither robot consistently covered my shallow steps or sun shelf. The Premier backed away when too much of its body left the water, and the Clear missed those areas on some cycles. Before starting either cleaner, I brush shallow dirt toward the main floor. A full-size corded robot does not remove the need for a pool brush.

Waterline results also depend on finish, wall angle, and obstacles. "Waterline cleaning" means the model is designed to work there; it is not a guarantee that every inch of tile gets the same contact on every run.

The UV Lamp Should Not Decide the Purchase

The Clear UV contains a UV-C lamp in the water path. Clear says the lamp treats water passing through the machine. The owner manual still tells users to maintain normal chlorine or salt sanitation and balanced chemistry.

I found no published UV dose, lamp irradiance, contact-time calculation, third-party certification, or laboratory reduction data for this robot. Without those numbers, I cannot tell you how much the lamp reduces a specific organism or how its contribution compares with a plumbed UV system. I also cannot credit it for water clarity that may have come from filtration and normal chemistry.

There is a safety chore attached to it. Clear instructs owners to keep people out of the pool while UV is enabled, leave the lamp submerged, turn it off before retrieval or service, and never look at it directly. If you will not follow those steps, leave the UV function disabled or consider the lamp-free Clear S.

Buy the Clear UV for the cleaning platform, basket, filters, controls, and coverage. Treat the lamp as an unquantified supplement, not a chlorine replacement or the reason to spend $1,999.

Controls, Cable, and the Work Between Cycles

The Premier's timer lives on its power supply. I could choose daily, every other day, or every third day operation for the coming week. It did not need an account, an app, or a Wi-Fi signal near the pool. I reset the schedule as part of filter maintenance.

The Clear keeps useful buttons on its control box and adds the phone app for weekly schedules, cleaning modes, cycle changes, manual steering, and pickup mode. The automatic route covered my pool well enough that I rarely steered it, but setting specific days and times is useful.

Both have cable swivels. My Premier cable did not knot during more than four years, although I still stored it loosely and gave it room beside the pool. A swivel reduces twist; it does not excuse dropping a tight coil into the water or leaving the cord in harsh sun.

Routine care for either one includes:

• emptying the media before debris restricts flow;
• spraying pleats from both sides;
• checking the intake and brushes for hair or string;
• letting the robot drain before lifting;
• straightening and loosely storing the cable; and
• brushing steps, shelves, corners, and any strip the cycle missed.

Warranty and Value

Clear currently asks $1,999 and lists a three-year limited warranty on manufacturing defects in the robot, control box, cable, and UV module. Brushes and filters are wear items. Clear also says unauthorized repair and purchases outside its authorized network can void coverage.

Maytronics currently lists the Premier at $2,499 with a three-year warranty. Specialty dealers often advertise it around $1,999, but prices and box contents move independently. A cheaper Premier without the bag or pleated set you wanted is not the same value as the tested package.

The Premier has the stronger durability evidence in my yard. Mine ran for more than four years without a motor-box, power-supply, cable, or impeller repair. Around year three I replaced stretched tracks and worn brushes, and I replaced filter media as needed. The Clear had only three months behind it when reviewed, so its equal warranty is useful but not proof of equal service life.

Who Should Skip Both

Skip both if you have an above-ground pool; these are manufacturer-rated in-ground models. Skip both if a 20- to 28-pound dry robot is unsafe for you to lift from the water. A lighter model may be the better tool even if it gives up waterline coverage.

Neither is a cure for algae, poor circulation, or unbalanced water. Neither consistently cleans shallow shelves and steps. If those are your main problems, spending more on the robot does not fix the mismatch.

My Pick

I would buy the Clear UV for ordinary in-ground-pool maintenance. Top access removes friction from the chore I perform most often, the included pleated filters suit the dust and pollen in my pool, and the schedule is more flexible.

I would buy the Dolphin Premier for severe seasonal leaves, provided the exact package includes the oversized bag. It also makes sense for someone who wants a button-operated weekly timer and values my four-year ownership record more than app control.

The choice is not 8,500 GPH versus 4,500 GPH, and it is not UV versus no UV. It is the basket you rinse every week against the bag you want during the worst month of the year.
