Dolphin Premium 60

A set of water jets that press the robot against the wall so it keeps traction while scrubbing the waterline and stays on course on the floor. It is the mobility system shared with the M600 and T60.

The M600 and T60.

Unbox the robot and strip off every piece of plastic wrap, including the wrap around any white foam climbing rings. Put the power supply at least 12 feet from the pool edge, in the shade if you can, and plug it straight into the outlet rather than an extension cord. Unroll only as much blue cable as the longest side of your pool and leave the rest coiled on the deck.

• Connect the blue cable to the power supply: line up the plug with the notch, then turn it clockwise until it locks.
• Plug the power supply in, but do not switch it on yet.
• Set the robot in the water at the middle of the pool's long axis and let it sink. If it has foam brushes or rings, hold them under until they are soaked.
• Press ON/OFF on the power supply. The robot starts in the direction it is facing.

A robot is built to maintain a pool that is already balanced and netted of large debris. Use the fine (coarser) filters for the first cycles of the season, never pull the robot by its cable while it is running, and remember that a cycle you interrupt restarts from the beginning next time.

Lift the robot out after each cycle and keep both the robot and the power supply out of direct sun, heat and cold. A caddy keeps it off the ground; coil the cable loosely so it never kinks. The power supply belongs in a covered spot at least 12 feet from the water, since it is splash-proof but not waterproof.

For the off-season, store the robot on its caddy in a ventilated space that stays between 41°F and 113°F, and keep it away from pool chemicals, whose fumes corrode plastics and electronics over time.

A modernized design with the LED moved to a new position, a sleeker drive-system panel and a handle and bumper in matching colours. Under the shell it is the same robot: CleverClean navigation, dual-drive motors and the PowerStream mobility system. Two features are new, both in the MyDolphin Plus app: a water temperature indicator and a three-level filter indicator that tells you how full the basket is.

MyDolphin Plus connects the power supply to your Wi-Fi so you can schedule and start the robot from anywhere. Your network must broadcast on 2.4 GHz, the password must be shorter than 32 characters with no spaces or special characters, and the signal at the power supply needs at least two bars. iOS 10 or Android 5 and later are supported.

• Plug in the power supply and connect the blue cable; the connectivity LED flashes blue. Put the robot in the water and press ON/OFF.
• Open the app, accept the permissions, create an account and scan the QR code on the side of the power supply (or search manually). Bluetooth pairing finishes when the LED turns solid blue.
• Enter your Wi-Fi name and password. The LED alternates green and blue while it joins the network and turns solid green when it is on the cloud.

If the progress bar stalls at 0 to 10%, restart the app close to the power supply and check the network name; at 10 to 50%, confirm the 2.4 GHz requirement; at 50 to 90%, restart your router. A Wi-Fi power supply cannot be added to a robot that did not ship with one.

Balanced water. Too little chlorine lets algae clog the filters and starve the motor of flow; a pH above the recommended range stops the robot climbing walls. After a shock or flocculant treatment, wait 24 hours before the robot goes back in. Keep the water between 43°F and 95°F; below 59°F, climbing suffers.

• Alkalinity: 80 to 120 ppm
• pH: 7.2 to 7.6
• Calcium hardness: 150 to 250 ppm
• Free chlorine: 1.0 to 3.0 ppm
• Cyanuric acid: 30 to 50 ppm

Saltwater pools are fine up to 5,000 ppm of salt. Rinse the robot with tap water after each cycle to stop deposits building up.

It is better to take it out after each cycle, empty and rinse the filters, and store it dry out of the sun. Models with a weekly timer or an Eco mode are designed to stay in for the week they are scheduled, as long as the water is balanced; clean the filter at the end of the week. Whatever the model, lift the robot out before anyone swims.

With CleverClean, a navigation program based on timing rather than mapping. The robot sweeps the floor in a pattern and, on models that climb, heads up the walls and along the waterline every four to six minutes. It starts off in whatever direction it is facing, which is why we suggest placing it in the middle of the pool along the long axis, and it is happy to work while your pool pump is running.

Register online at registration.maytronics.com with the robot's 10-character serial number and your Pool Express receipt. The serial number is printed on the box label, on the warranty card and on a barcode label inside the robot's housing. The form asks for the serial number, your details, the purchase date and store, and an uploaded receipt or invoice showing the date, product and price; then you agree to the terms and submit. Keep the confirmation with your receipt. Because Pool Express is an authorized Maytronics dealer, the full 3-year warranty applies.

A standard 120-volt outlet, ideally one protected by a GFCI. The robot draws under one amp while it runs, roughly 100 to 180 watts, so a cycle costs a few cents in electricity.

Turn the power supply off and unplug it. Pull gently on the floating blue cable until the robot reaches the side, then take it by the handle and lift it slowly so the water drains before it clears the edge. Never yank the cable, and never lift the robot by it. If reaching down is awkward, a retrieval hook that clips onto a standard pool pole makes the lift easy; resting the robot on the coping for a minute lets the rest of the water run out.

Yes. Pool Express is an authorized Maytronics dealer, so every Dolphin Premium 60 we sell is a new unit that registers with Maytronics for the full manufacturer warranty, and our Pool Pros handle any warranty question for you. Buying from an unauthorized seller can void that coverage, which is why Maytronics asks you to buy from a dealer. You also get our 30-day trial and low price guarantee.

Some Dolphin models do and some do not. Where modes are offered they differ in cycle length and coverage, and you select them in the MyDolphin or MyDolphin Plus app. The manual for this model lists exactly which modes it has and how long each cycle runs; our Pool Pros can confirm before you buy.
