1. INTRODUCTION
Thank you for purchasing the Dolphin Liberty cordless robotic pool cleaner.
Like all Dolphin robots from Maytronics, your new Dolphin Liberty robot is designed for easy,
reliable and efficient operation.
Please read this instruction manual carefully and be sure to follow all the recommendations regarding
operation and care of your Dolphin Liberty. This is essential for optimal cleaning and to protect your
robot at all time, whether in use or in storage.
1. The Dolphin Liberty is a cordless, battery-powered robotic pool cleaner designed to clean any
residential pool up to 15m (50ft) in length. It is particularly suited for pools with irregular shapes
and/or in-pool features, such as bridges, fountains, pillars, and other obstacles that may hinder the
free movement of a power cable.
2. The Dolphin Liberty is a wall-climbing model; it cleans the pool floor, walls, and waterline without
intervention.
3. The robot is battery-operated and must be charged before each use by the charger that is
supplied with it.
4. The default duration of the cleaning cycle is 1hr. and 15 min. The duration can be changed to a
1hr. and 30 min. This is done with the remote control.
5. Charging the robot takes 4-5 hrs., after which the robot is ready for use.
6. Upon completion of an operating cycle, the robot automatically moves to one of the pool walls
before switching off. This makes it easier to take the robot out of the water for charging and
cleaning the cartridges.
7. If the robot completes its work and stops at an inaccessible location inside the pool, it can be
steered with the remote control to a more accessible location, this must be done within 12 hours
from the robot’s completion of the operating cycle.
8. If required, the robot can be steered with the remote control during its operation.
9. The pool cleaner can work under a pool cover.
2. WARNINGS AND CAUTIONS
1. Use only the original charger supplied with the robot and manufactured by Maytronics.
2. Place the charger in a shaded dry area during both charging and storage.
3. Always place the charger at a minimum of 3m (10ft) distance from the edge of the pool,
especially during charging.
4. Prior to connecting the float and charger for charging purposes, verify that the connector
and socket are dry and clean.
5. Before operation, disconnect the charging cable and close the charging socket cover.
6. Do not open or disassemble the motor unit in any way.
7. Ensure the electrical outlet used for charging is protected by a ground fault interrupter (GFI)
or an earth leakage interrupter (ELI).
8. Do not enter the pool while the pool cleaner is working.
9. The pool cleaner must be charged before storage.
10. The pool cleaner is not to be used by children or persons with reduced physical,
sensory or mental capabilities, or lack of experience and knowledge, unless they
have been given supervision or instruction.
