Zodiac CNX pool robots: which one to choose? | ioT-Pool

Published October 2026 · 4-minute read

Choosing a pool robot may seem simple, but there are several factors to consider. Within the Zodiac CNX range, there are different models designed to meet different needs.

In this guide, we explain the main differences between the models available at ioT-Pool, so you can find the robot that best suits your pool.

1. Before you choose: what should you consider?

The most advanced model is not necessarily the best choice for every pool. The right model depends mainly on four factors:

The size of your pool, as each model has a recommended maximum pool size.

The areas you want to clean, as the different CNX models can clean the floor, walls and waterline, for a more thorough clean.

The type of filtration, as there are models with single or dual filtration systems. Dual filtration offers high retention capacity, regardless of the size of the dirt particles in the water.

The features and convenience, which often make the difference in the small details. Does your CNX have Wi-Fi connectivity? Can it be controlled through the app? Do you need a Lift System that makes it easier to take the robot out of the pool, so the process is lighter and less physically demanding? Would you prefer a model with a transport caddy included?

2. Compare the models

3. What does IoT-Pool recommend?

There is no single CNX that is ideal for every pool. That is why, at ioT-Pool, we highlight three models for different needs:

CNX 25: compact and effective

If you are looking for a compact robot with good cleaning power, the CNX 25 is worth considering. Dual filtration effectively traps different types of dirt, while cleaning the floor, walls and waterline ensures complete pool maintenance.

Recommended for: those looking for a balance between simplicity, effectiveness and filtration capacity.

CNX 50 iQ: more convenience

If you value features that make using your robot more practical, the CNX 50 iQ brings together several solutions designed to make everyday life easier. It includes Wi-Fi, Lift System, Swivel and a transport caddy, so you can control the robot through the app and remove and move it more easily.

Recommended for: those looking for convenience and more features.

CNX-Li 52 iQ: cable-free freedom

For those who would rather not deal with cables, the CNX-Li 52 iQ offers a different experience. It runs on a lithium-ion battery for cordless use and includes Wi-Fi and control through the iAquaLink app.

Recommended for: those who value freedom of use, practicality and connectivity.
