Frequently Asked Questions
How does the Liberty 400 compare to the Liberty 300 and Liberty 600?
All three Liberty models share cordless operation, inductive charging, Click-Up retrieval, Eco Mode, CleverClean navigation, and sun ledge cleaning. The Liberty 400 adds the MyDolphin Plus app for smartphone control, which the Liberty 300 lacks. The Liberty 600 further adds an extra large filter (vs. large on 400), step cleaning capability via JetIQ, and a 3-year warranty the same as the 400. If app control matters to you but you don't need step cleaning, the Liberty 400 is the right choice.
How does Click-Up work?
Click-Up is a sound-activated retrieval system. When you clap or make a sharp sound near the pool, the Liberty 400 responds by rising to the surface — so you can retrieve it without reaching into the water or fishing for it with a pole.
What does inductive charging mean?
Inductive charging transfers power wirelessly without exposed metal contacts. Traditional chargers with metal pins are prone to corrosion and rust from pool water exposure. Inductive charging eliminates this entirely for longer charging system life.
Does it clean sun ledges?
Yes. The Liberty 400 cleans sun ledges and tanning shelves in addition to the floor, walls, and waterline.
What can I do with the MyDolphin Plus app?
The MyDolphin Plus app lets you schedule weekly cleaning cycles, select cycle options, and trigger a spot clean remotely from your smartphone via Wi-Fi.
