Premium user experience

"Click-Up" water retrieval

No more diving or pulling on a cable! Use the provided "Clicker" pole: shake it in the water, and the Liberty 300 automatically climbs the wall so you can easily grab it by hand.

Weekly eco mode

Going away for a few days? Activate Eco Mode. The robot will perform three 40-minute cycles (bottom only) spread throughout the week to keep the water crystal clear until you return.

Simplified maintenance (top access)

The filter basket is accessible directly from the top of the robot. A simple click allows you to remove it, rinse it with a water jet, and put it back in place in a few seconds.


How does the Dolphin Liberty 300 clean?

The operation of the Dolphin Liberty 300 is based on complete autonomy. Once immersed, this Dolphin pool cleaner uses its intelligent navigation to perform a complete cleaning (bottom, walls, and waterline) or bottom cleaning only, depending on your choice. It combines powerful active brushing that dislodges impurities and a dual-level filtration system (fine and ultra-fine) that captures everything from leaves to sand. Its standard cleaning cycle lasts 2h30, but you can activate Eco mode to keep the pool clean all week with 3 mini-cycles of 40 minutes.

 

What is the battery life of the Dolphin Liberty 300?

The battery life of the Liberty 300 is designed to cover large pools without interruption. Its high-capacity Lithium-ion battery allows for continuous operation of up to 2h30 per cycle. The strong point of this model is its inductive charging: simply bring the magnetic connector close to the back of the robot to start charging. The full charging time is approximately 6 hours, ensuring optimized battery life thanks to the absence of metallic charging ports prone to corrosion.

It's a high-performance Dolphin Liberty pool robot that integrates the Click-Up™ function (the robot climbs the wall when you call it with the sound pole). Its 15 m³/h suction performance ensures no debris escapes it, making it one of the most powerful cordless robots on the market.

Water retrieval is the simplest on the market: thanks to the Click-Up system, the robot climbs by itself to the waterline. It's the ideal robotic pool cleaning solution for those who want zero technical hassle.

How do I maintain the Dolphin Liberty 300?

Maintenance has been designed to maximize the device's durability. Ease is the key word: after each cycle, simply remove the combined basket, open it, and rinse each filter with a water jet. It is recommended to store the robot in the shade between uses and not let the basket get clogged. Regular filter cleaning ensures consistent suction power in the long term.
