What the Liberty 300 Adds Over the Liberty 200
Built on the same nimble 17.9-lb cordless tracked chassis as the Dolphin Liberty 200, the Dolphin Liberty 300 solves the two biggest everyday pain points of battery pool robots: fishing the cleaner out with a pole and recharging after every single run.
- Click-Up™ Acoustic Retrieval: Dip the included rattle wand in the water and give it a shake—sound waves travel underwater to trigger the Liberty 300 to climb straight up the nearest wall to meet your hand.
- Eco Mode: Leaving for the weekend? Eco Mode automatically runs three 30-minute floor-maintenance cycles across the week on a single charge.
- Dual Filtration Media: Ships with extra ultra-fine pleated panels in addition to the standard fine mesh basket.
Availability tip: If the Liberty 300 is currently out of stock, see the in-stock Dolphin Liberty 200 or chat with a Pool Robot Expert for immediate cordless alternatives.

Common Questions
Dolphin Liberty 300 FAQ
How does Click-Up retrieval work underwater?
Wi-Fi and Bluetooth signals can't travel through water, but sound waves do. Shaking the included Click-Up™ rattle wand in the pool sends an acoustic frequency the Liberty 300 recognizes, prompting it to climb the wall to the surface.
What is the difference between Liberty 300 and Liberty 400?
The Liberty 400 adds tile waterline scrubbing, Bluetooth myDolphin™ Plus app customization, and a 3-year warranty.
What can I buy today if the Liberty 300 is out of stock?
Our Dolphin Liberty 200 shares the same cordless motor, battery, and magnetic charger—and is ready to ship—or compare our top corded value, the Dolphin Cayman.
