Smart Pool 2026: Guide to Automating Water Care, Filtration and Cleaning

A smart pool in 2026 starts with a floating water analyser that measures pH, sanitising power (ORP) and temperature and tells you what to add, followed by a programmable robot and, if you want to go further, a salt chlorinator or variable-speed pump you can control from your phone. To get started, the Ondilo ICO Pool V2 is the most complete analyser, the iopool EcO the easiest to live with, and the Dolphin S300i the most balanced robot for a family pool.

This guide is based on manufacturer specifications, specialist press reviews and verified buyer feedback. It covers each building block (water, treatment, filtration, cleaning, cover and safety) and shows where to start depending on your pool. For robots in detail, see our pool cleaning robot comparison.

What a smart pool actually automates

Water monitoring

Healthy water depends on a simple balance: pH usually kept between 7.2 and 7.6, enough active sanitiser and filtration matched to the water temperature. A connected analyser measures these parameters several times a day and warns you before the water turns. It replaces most test strips, but an occasional manual check is still worthwhile.

Automatic treatment

A salt chlorinator produces chlorine directly from the lightly salted pool water. Combined with pH control and a redox (ORP) probe, it adjusts its output to actual demand. Connected models show readings on your phone and let you change settings remotely.

Filtration

The filtration pump is the biggest electricity user in a pool. A variable-speed pump runs longer but slower, which cuts consumption significantly compared with a single-speed pump. Wi-Fi versions are scheduled from an app.

Cleaning

A programmable robot cleans the floor, walls and waterline on a schedule. The app is used to start a cycle, choose a mode and know when the filter needs emptying.

Cover and lighting

A motorised cover reduces evaporation, night-time heat loss and leaf debris. Controllable LED lighting completes the setup for evening use.

How to choose

Your pool’s treatment

Chlorine, bromine or salt: check compatibility first. Ondilo offers a chlorine/bromine version and a salt version of its ICO Pool V2; iopool states compatibility with chlorine, bromine, active oxygen and UV treatment. A salt chlorinator, of course, only applies to salt pools.

Connectivity at the poolside

Home Wi-Fi often struggles to reach the end of the garden. Some analysers use a gateway placed between the house and the pool (iopool), others connect directly over 2.4 GHz Wi-Fi with Bluetooth as a backup (Ondilo). Check the signal at the water’s edge before buying, or plan for an outdoor repeater.

Probes and battery

pH and ORP probes wear over time: check whether they can be replaced and how power is handled. The ICO Pool V2 is recharged over USB at the start of the season and its probes are removable; the iopool EcO runs on a non-rechargeable battery designed to last about two years, after which you replace the module.

Quality of the recommendations

An analyser is only as useful as its advice: which product to add, how much, and when to run filtration longer. Also check whether the app is free or whether some features are paid. iopool highlights an app with no subscription.

Ecosystem

If you are starting from scratch, staying within one range (chlorinator, pump and robot from the same manufacturer) lets you control everything from a single app. If your plant room is already equipped, a floating analyser can be added with no work at all.

Recommended equipment for 2026

1. Ondilo ICO Pool V2: the most complete analyser

The Ondilo ICO Pool V2 is a floating analyser designed by a French company. It measures pH, ORP and water temperature every hour; the salt version also tracks conductivity, which helps monitor salt levels. Its probes are removable for maintenance, it connects over 2.4 GHz Wi-Fi and Bluetooth Low Energy, and its rechargeable lithium-ion battery is designed to last the season. The housing is rated IP68, with a 2-year warranty that includes the probes. The app anticipates changes in the water and only suggests dosing when it is needed.

Strengths: personalised recommendations, dedicated salt-pool version, no gateway to install. Limitations: the most premium analyser here; Wi-Fi must reach the pool. Best for: owners who want precise monitoring, including with a salt chlorinator.

2. iopool EcO: the easiest to live with

The iopool EcO is a floating puck about 22 cm long. Three sensors measure temperature, pH and ORP, and data is sent roughly every 15 minutes through a Wi-Fi gateway placed between the house and the pool. The battery is not rechargeable: it is designed to last about two years without charging or calibration, after which the module is replaced. The free app, with no subscription, calculates how much product to add.

Strengths: no charging or calibration, gateway improves range, broad compatibility. Limitations: module to replace after roughly two years; no salt-level tracking. Best for: a first step into smart pool care, with the best value for money.

3. Zodiac eXO iQ: automated salt treatment

The Zodiac eXO iQ is a salt chlorinator with built-in Wi-Fi, designed for pools of up to 160 m³ depending on the version. With the optional pH Link or Dual Link modules, it automatically regulates pH and chlorine output based on the redox reading. From the manufacturer’s app you can follow water quality and control other compatible equipment such as the filtration pump, heater or lighting. Zodiac states a 3-year warranty on the electrode, and an eXO iQ LS version is designed for low-salinity water.

Strengths: genuinely automated treatment, central control of equipment, widely supported by pool professionals. Limitations: salt pools only; plumbed into the hydraulic circuit, ideally by a professional. Best for: salt pools, or owners ready to switch to salt and stop dosing chlorine by hand.

4. Dolphin S300i: the benchmark corded robot

The Dolphin S300i by Maytronics cleans the floor, walls and waterline of pools up to 12 m long, with two active brushes and a multi-layer filter that opens from the top. Its 18 m cable has an anti-tangle swivel, the default cycle lasts 2 hours and the MyDolphin Plus app starts and schedules cycles. Maytronics states a 3-year warranty.

Strengths: no battery to manage, easy-to-empty filter, wide dealer network. Limitations: cable to lay out and store, no surface skimming. Best for: standard in-ground pools cleaned several times a week.

5. Beatbot AquaSense 2 Pro: the most complete cordless robot

The Beatbot AquaSense 2 Pro cleans the floor, walls and waterline, skims the surface and can clarify the water with a natural agent that clumps fine particles together. Its battery is rated for up to 5 hours on floor and walls, it covers up to 360 m², navigates with ultrasonic sensors and is controlled over Wi-Fi or Bluetooth.

Strengths: no cable, surface skimming, long battery life. Limitations: premium model, heavy to lift out, clarifier refills to buy. Best for: large pools surrounded by trees. Other cordless options are covered in our pool cleaning robot comparison.

Variable-speed pump: smarter filtration

The pump runs several hours a day all season long, so it weighs most on the electricity bill. A variable-speed pump lets you filter for longer at low speed, switch to high speed for backwashing or a robot cycle, and run more quietly. Connected models such as the Zodiac FloPro e30iQ with built-in Wi-Fi are scheduled from an app.

Replacing a pump involves the hydraulic circuit and the electrical panel: have it done by a pool professional or a qualified electrician, and check compatibility with your filter and pipework. If you keep your current pump, a programmable filtration control box fitted by a professional already lets you match run time to water temperature.

Cover, alarm and safety

In France, every private in-ground or semi-in-ground pool must have at least one standardised safety device: a barrier (NF P90-306), an alarm (NF P90-307), a cover (NF P90-308) or an enclosure (NF P90-309). Rules differ in other countries, so check what applies where you live. A compliant automatic cover can serve as the safety device, provided it is closed and locked whenever the pool is unsupervised. Some motorised covers can be operated remotely or integrated into a home automation system, but always keep the pool in sight while it opens or closes.

No equipment replaces adult supervision: keep children within sight near the water, even with an alarm or a cover. On the maintenance side, a cover reduces evaporation, keeps heat in overnight and limits leaves and insects, and therefore chemical use.

Where to start

1. A water analyser: the device that changes day-to-day care the most, with no installation work. It ends test strips and guesswork dosing.
2. A programmable robot: it removes the most frequent chore.
3. Filtration: a variable-speed pump or temperature-based scheduling, best planned when the pump is due for replacement.
4. Automatic treatment: a salt chlorinator and pH control if your pool is on salt or you are ready to switch.
5. Cover and lighting: a bigger project, often carried out during a renovation.

Mistakes to avoid

• Buying an analyser that does not match your treatment: with some brands, the salt and chlorine versions are not interchangeable.
• Ignoring Wi-Fi at the poolside: without a stable connection, alerts never arrive.
• Relying on ORP alone: it indicates sanitising power, not an exact chlorine level. An occasional manual check (free chlorine, stabiliser, total alkalinity) is still useful.
• Forgetting the probes in winter: take the analyser out at the end of the season and store it as the manufacturer recommends.
• Confusing automation with safety: an app replaces neither a compliant safety device nor watching children.

Installation and electrical safety

Anything plugged in near water must be supplied by a circuit protected by a 30 mA residual current device (RCD). A robot’s power supply should sit away from the pool, sheltered from splashes, at the distance given in the manual. Chlorinators, pumps, filtration control boxes and underwater lights are wired in the plant room: have this work done by a qualified electrician or pool professional. Never swim while a robot is running.

Verdict

To make a pool smart without any building work, start with a water analyser: the Ondilo ICO Pool V2 for the most complete monitoring, especially on salt, or the iopool EcO for the simplicity of a sensor that needs no charging for about two years. Add a programmable robot such as the Dolphin S300i, or the Beatbot AquaSense 2 Pro if you want cordless cleaning and surface skimming. Finally, if your pool runs on salt, the Zodiac eXO iQ automates treatment and brings equipment control into one place.
