Dolphin Liberty 300 Review

Dolphin Liberty 200

The Dolphin Liberty 300 is the first battery-powered robotic pool cleaner from Dolphin, set to be released in Spring 2023. While details are still limited, what we do know is that it is light and compact, making it perfect for all types of pools up to 10m long including above ground pools. It has a 1.5-hour cleaning cycle that can clean both the bottom and walls of the pool with ease.

Dolphin Liberty 300 Inductive Charging

Big Downside

The downside to this particular model is that you have to take it out of the water when charging as you cannot replace the battery between charges - you must charge for 6 hours before you can use it again. However, this makes up for its ergonomic design which makes it easy to handle and empty quickly when removed from water as well as its large capacity inner filter basket with top access and transparent lid so finding debris won't be an issue.

Dolphin Liberty Family

In comparison to other models such as Dolphin Liberty 600, Liberty 700s, and Liberty 800s, which all feature a removable and replaceable battery (Coming in 2024!), the Dolphin Liberty 200, 300, and 400 only have inductive charging capabilities.

Will it climb the walls?

The Liberty 300 features tracks for perfect grip on all surfaces, an active front brush, advanced scanning software and navigation system CleverClean™, and a reliable warranty from Maytronics - world leading manufacturers in robotic pool cleaners. We don't know if it will have waterline cleaning yet, a feature found among Dolphin's top robotic pool cleaners such as the Dolphin Sigma, Dolphin Premier, and Dolphin Quantum. We are also excited to find out if the battery can sustain the cleaning power of corded units.
