Dolphin LIBERTY 300 Cordless Robotic Pool Cleaner – 99998130-US
Cordless Freedom with Floor, Wall & Waterline Cleaning
The Maytronics Dolphin LIBERTY 300 Cordless Robotic Pool Cleaner brings powerful Dolphin cleaning performance to a completely cordless design. Built for swimming pools up to 33 ft (10 m), the LIBERTY 300 automatically scrubs and cleans the pool floor, walls and waterline without a power cable getting in the way.
The LIBERTY 300 combines powerful active scrubbing with fine and ultra-fine filtration to capture dirt, dust and pool debris. Its top-access filter system makes removing and rinsing the filter quick and convenient after cleaning.
Maytronics Magnetic-Connect inductive charging makes recharging simple. When the cleaner needs power, simply connect the magnetic charger without opening charging ports or plugging a cable directly into the robot.
For regular pool maintenance, Eco Mode divides a single battery charge into shorter cleaning cycles throughout the week. The Cycle Selector also allows you to choose between floor-only cleaning and full pool coverage depending on your cleaning needs.
When cleaning is finished, the innovative Click-Up system makes retrieval easier. Shake the included Clicker in the water and the LIBERTY 300 responds by climbing the nearest wall so it can be conveniently removed from the pool.
