No cable, no power supply by the pool

Dolphin Liberty Cordless Robotic Pool Cleaners

Liberty is Dolphin's cordless family. Every model runs on a lithium battery, charges through a magnetic inductive connector and parks itself at the wall when the cycle ends. The 200 and 300 cover pools to 33 ft; the 400 adds app control and a 3-year warranty; the 600 stretches to 50 ft with a 3-hour cycle.

Who the Dolphin Liberty Lineup Suits

Go cordless when the cable is the thing you dislike about pool robots. The Liberty 200 is the value entry, the 300 adds waterline cleaning and Click-Up™ retrieval, the 400 brings the myDolphin™ Plus app and 3 years of warranty, and the 600 is the one for pools over 33 ft.

The whole Liberty line Every model is below with its price, specs and its own page; the comparison table puts them side by side.

Good fit when

  • Pools where a cable snags on steps, ladders or an uneven floor
  • Owners who run the robot a few times a week and charge overnight
  • Pools up to 33 ft (200/300/400) or 50 ft (600)

Strengths

  • Nothing to coil: drop it in, lift it out at the wall
  • Magnetic-Connect charging with no exposed pins
  • Floor and wall coverage on every model; waterline from the 300 up

Before you buy

  • Run time is limited by the battery; very dirty pools may need two cycles
  • A 2.5–3 hour cycle, then charging, so no back-to-back runs
  • Corded Max-Series™ robots give more suction for the money

Next step: Start with the Liberty 200, or read whether a cordless cleaner is worth it.

Dolphin Liberty buying guide

What separates the models, and which current Dolphin to price each one against.

The four Libertys

The Liberty 200 covers floors and walls on pools to 33 ft in a 2.5-hour cycle and is the entry point to the line. The Liberty 300 adds waterline scrubbing and Click-Up™, so it surfaces for pickup. The Liberty 400 keeps the 33 ft rating and adds myDolphin™ Plus app control and a 3-year warranty. The Liberty 600 is the flagship: 50 ft, a 3-hour cycle, Multi-Layer filtration and the Maytronics One app.

Battery care in one paragraph

Charge in the shade, store the robot around half charge over winter, and keep the magnetic contacts clean. Do that and the battery lasts season after season; every Liberty is covered by a 2- or 3-year Maytronics warranty.

Quick answers

Dolphin Liberty Questions

How long does a Liberty run on a charge?

Does the Liberty climb walls?

Yes, every Liberty climbs walls. The 300, 400 and 600 also scrub the waterline.

Which Liberty is the best value?

The Liberty 200 for most pools up to 33 ft; an open-box unit saves more when one is available. Choose the 400 if you want the app and the longer warranty.
