Dolphin Premier

The Dolphin Premier is Maytronics' corded robot for in-ground pools up to 50 feet, listed at $2,499 with a three-year warranty. It cleans the floor, walls and waterline on a three-hour default cycle, has no app, and schedules itself from a weekly timer on the power supply.

The Premier on sale now

The Premier name has been around for years, and descriptions of it tend to carry features that Maytronics' current page for 99996339-SPL does not list. This site's own robot roundup described it, until September 2026, with SmartNav 2.0 navigation and multi-media filtration that swapped between NanoFilters, cartridges and a leaf bag.

Maytronics' specification table today says something narrower:

• Navigation: CleverClean.
• Filtration: an interchangeable filter bag and cartridge, loaded from the bottom, with a fine filter kit in the box.
• Suction rate: 4,500 gallons per hour.
• Brushes: two combined brushes.
• Weight: 20.3 pounds, which Maytronics markets as lightweight.

Buy against that table, not against a description of an earlier Premier.

Setting it up

• Keep the power supply at least 12 feet from the pool's edge, in the shade, plugged into an outlet with a ground fault interrupter. Never use an extension cable.
• Soak the brushes if they are combined or Wonder brushes: squeeze them gently in the water until they are saturated.
• Put in only the cable it needs to cover the pool, and leave the rest rolled up outside.
• Lower it in, let it sink, and switch the power supply on. It runs a full cycle and switches itself off.

Nobody should be in the pool while it runs. To take it out, use the handle, never the cable.

The weekly timer

Scheduling lives on the power supply, not in an app. When you switch it on, the three LEDs blink for five seconds, and pressing SELECT during that window picks a schedule for the week:

• LED 1: a full cycle every day, seven times a week.
• LED 2: every other day, three times a week.
• LED 3: every three days, twice a week.

The robot always starts one cycle at setup. If you press nothing in the first five seconds, it runs that one cycle only. While the timer is running, the LED blinks between cycles, and at the end of the week the power supply switches itself off, so the schedule has to be set again each week.

The full filter indicator

A red LED on the power supply watches the filter:

• Blinking: the filter is partially blocked.
• Lit: it is blocked and has to be emptied.

If the light stays on after you have emptied and cleaned the filter, press RESET while the robot is working.

Cleaning the filter

Maytronics says to wash the filter after every cycle, because a clogged filter reduces both the robot's scanning and its cleaning. The filter comes out of the bottom: turn the robot upside down, open the bottom lid and pull it out, then hose it clean.

Periodic maintenance

Unplug the power supply first. Take off the impeller cover, clean around the impeller housing, and put it back. When refitting, Maytronics' guide says to place the cover at an angle so the notch sits on the second ring of the spring.

The cable, and storage

To take the kinks out of the cable, stretch it out completely and leave it in the sun for at least a day.

Store the robot in the shade on its caddy, or upside down if there is no caddy. Coil the cable and keep everything somewhere cool and dry, out of direct sunlight, excessive heat and frost.

Water it is rated for

Maytronics limits the Premier to:

• Chlorine at no more than 4 ppm.
• pH between 7.0 and 7.8.
• Water temperature between 43°F and 93°F.
• Salt at no more than 5,000 ppm.
• Depth between 2.6 and 16.4 feet.

A pool that is still below 43°F in spring is outside its rating.

What Maytronics does not publish

• A parts diagram. Maytronics lists 19 spare parts for the Premier on a parts page for this robot, from the power supply and cable to the impeller, tracks, brushes and filters, but publishes no exploded diagram showing where they go.
• A matching manual. The user manual its portal serves for this part number is titled Dolphin Classic 5 / Top 5, with a float setup the Premier's own documents do not describe, and a remote control that comes standard on the Top 5 but is only an optional accessory for the Premier. The quick start guide is the only document that carries the Premier's name and part number, and it is the one this page follows.
• US warranty terms. Maytronics' US terms of sale point to its limited warranty at a link that reads, literally, "[LINK]".

Where Maytronics' documents disagree

• Power supply distance. The Premier quick start guide says 3.5 meters, 12 feet from the pool's edge. The Classic 5 / Top 5 manual it links says 3 meters, 10 feet. Use the larger figure.
• Scrubbing. The product page's feature list promises powerful active scrubbing; the same page's specification table lists Active Brush: No.

Making a warranty claim

Three years, serviced through an authorized Maytronics dealer and valid only in the country of purchase. Register the robot, and keep the invoice with its date and serial number, because that is what a claim asks for.
