The Zodiac CNX-Li 52 iQ is a 100% cordless pool robot that eliminates the floating cable during the cleaning cycle, covering the floor, walls and waterline in pools up to 10 x 5 m. The lithium-ion battery delivers a full 2-hour cleaning cycle according to the manufacturer, with remote control via the iAquaLink app. Designed for pool owners who want to automate cleaning without managing cables day to day.
Zodiac CNX-Li 52 iQ – Cordless Cleaning for Pools up to 10 x 5 m
The CNX-Li 52 iQ belongs to Zodiac’s Freedom range, designed for mid-sized residential pools. With no power cable, the robot is easy to place in and remove from the water and takes up minimal storage space. The iAquaLink app lets you check the battery charge level and receive end-of-cycle notifications from anywhere with a Wi-Fi connection.
Ideal for:
- Residential pools up to 10 x 5 m – sized to cover the floor, walls and waterline in this format without interrupting the cycle.
- Owners who prefer cable-free cleaning – with no floating cable during the cycle, placing and removing the robot is simpler and faster.
- iAquaLink app users – schedule cycles and receive end-of-cycle notifications via Wi-Fi, without needing to be poolside.
Technology and Capabilities of the Zodiac CNX-Li 52 iQ
Patented Cyclonic Suction for Fine Debris Collection
The CNX-Li 52 iQ uses high-powered patented cyclonic suction, according to the manufacturer. This technology keeps suction force stable throughout the cycle, capturing fine debris that conventional filters miss. The result: effective cleaning even in pools affected by fine dust or pollen.
Helix-Shaped Brushes for Floor and Wall Cleaning
The CNX-Li 52 iQ’s helix-shaped brushes collect debris more efficiently than flat brushes, including the finest particles. The helical geometry channels debris towards the suction zone as the robot moves, covering the floor, walls and waterline across both available cleaning modes.
Cordless Cleaning with Lithium-Ion Battery (25.4 V / 6.4 Ah)
The 25.4 V / 6.4 Ah lithium-ion battery delivers a complete cleaning cycle with no floating cable. The “floor only” mode runs for 1 h 30; the “floor, walls and waterline” mode runs for 2 hours. Without a power cord, placing and removing the robot is quicker and tangle-free.
Remote Control via iAquaLink App with Wi-Fi
The iAquaLink app lets you check the battery charge level in real time, receive end-of-cycle notifications and access remote updates. The connection is made over Wi-Fi, so you don’t need to be next to the pool. The robot is also programmable, allowing you to schedule cleaning cycles in advance.
Smart Sensors for Coverage Adapted to Pool Shape
The integrated smart sensors allow the CNX-Li 52 iQ to adapt its navigation to the shape and finish of the pool, whether rectangular, freeform or irregular. The tracked drive system with gear transmission ensures grip across different surfaces – liner, tile, concrete and fibreglass.
Transparent Lid for Filter Inspection Without Removal
The transparent filter compartment lid lets you visually check the level of accumulated debris without removing the robot from the water. The 4 L cartridge filter with 100 µ filtration is accessible from the top, making routine cleaning and maintenance straightforward.

Who Is the Zodiac CNX-Li 52 iQ Suited For?
The CNX-Li 52 iQ is suited to in-ground and above-ground pools up to 10 x 5 m, with liner, tile, concrete or fibreglass finishes, in rectangular, freeform or irregular shapes. Water pH should be maintained between 7.0 and 7.6 to ensure correct robot operation and effective wall cleaning.
Wall and waterline cleaning performance may be affected if the pH falls outside the recommended range or if algae or slime are present. Cleaning of right-angle corners and liner overlaps cannot be guaranteed 100% – a limitation common to all pool robots in this category. Steps and benches are also not effectively cleaned by this type of equipment.
Which Zodiac CNX iQ Model Is Right for Your Pool?
The Zodiac CNX iQ range includes corded models (Zodiac CNX 30 iQ, Zodiac CNX 40 iQ and Zodiac CNX 50 iQ) and the CNX-Li 52 iQ, which is the only cordless model in the line-up.

Frequently Asked Questions
What is the real battery life of the Zodiac CNX-Li 52 iQ in each cleaning mode?
The “floor only” mode runs for 1 h 30. The full “floor, walls and waterline” mode runs for 2 hours, as stated by the manufacturer. These figures correspond to a complete cycle with the 25.4 V / 6.4 Ah lithium-ion battery fully charged.
How do I clean and maintain the filter on the CNX-Li 52 iQ?
The 4 L cartridge filter is accessible from the top of the robot with no tools required. The transparent lid lets you visually check the debris level before removing it. To clean, simply take out the cartridge, rinse it with water and refit. The 526 cm² filter surface with 100 µ filtration retains fine debris effectively.
What is the difference between the CNX-Li 52 iQ and the CNX 50 iQ?
The CNX-Li 52 iQ is the cordless model in the range, powered by a lithium-ion battery with up to 2 hours of runtime per cycle. The Zodiac CNX 50 iQ is a corded model with continuous power, so there is no battery runtime limit. For frequent use where managing charge is undesirable, the CNX 50 iQ offers uninterrupted operation.
Does the Zodiac CNX-Li 52 iQ clean walls and the waterline in all pools?
The robot cleans walls and the waterline in pools up to 10 x 5 m with liner, tile, concrete and fibreglass finishes. Wall cleaning effectiveness depends on the water pH being between 7.0 and 7.6 and the absence of algae. Right-angle corners and liner overlaps cannot be guaranteed to be cleaned 100%.
How long does it take to fully charge the battery?
According to the operator’s technical datasheet, the full charge time is 5 hours. Some retail sources quote 4 hours. For the exact figure applicable to your market, please refer to the manufacturer’s official technical datasheet. The charging station is included in the box.
What is the minimum water depth required for the robot to operate?
The CNX-Li 52 iQ requires a minimum water depth of approximately 30 to 40 cm to operate correctly. In shallow areas of the pool below this depth, the robot may not function effectively. The safety system includes an automatic out-of-water cut-off.
Is the iAquaLink app free and compatible with iOS and Android?
The iAquaLink app is Zodiac’s official application for controlling the CNX-Li 52 iQ via Wi-Fi. It allows you to check the battery level, receive end-of-cycle notifications and access remote updates. For information on operating system compatibility and app availability, please refer to the manufacturer’s technical datasheet.
