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

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

This guide is based on manufacturer specifications, reviews in the specialist press and verified owner feedback. It walks through each building block (water, treatment, filtration, cleaning, cover and safety) and shows where to start depending on your pool. For a closer look at robots, see our robotic pool cleaner comparison.

What a smart pool actually automates

Water monitoring

Healthy water comes down to a simple balance: pH usually kept between 7.2 and 7.6, enough active sanitizer and filtration matched to the water temperature. A smart analyzer measures these readings 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 chlorine generator makes chlorine directly from the lightly salted pool water. Paired with pH control and an ORP (redox) probe, it adjusts its output to actual demand. Smart models show readings on your phone and let you change settings remotely.

Filtration

The pool pump is the biggest electricity user in a pool. A variable-speed pump runs longer but slower, which cuts energy use 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. You use the app to start a cycle, pick a mode and know when the filter needs emptying.

Cover and lighting

An automatic cover cuts evaporation, overnight heat loss and leaf debris. Smart LED lighting completes the setup for evening swims.

How to choose

Your pool’s sanitizer

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

Connectivity at the pool

Home Wi-Fi often struggles to reach the back of the yard. Some analyzers 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 you buy, or plan on an outdoor Wi-Fi extender.

Probes and battery

pH and ORP probes wear out over time: check whether they can be replaced and how the device is powered. The ICO Pool V2 recharges 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 analyzer 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 cost extra. iopool highlights an app with no subscription.

Ecosystem

If you’re starting from scratch, sticking with one brand (salt chlorine generator, pump and robot from the same manufacturer) lets you control everything from a single app. If your pool equipment is already in place, you can add a floating analyzer with no work at all.

Recommended equipment for 2026

1. Ondilo ICO Pool V2: the most complete analyzer

The Ondilo ICO Pool V2 is a floating analyzer designed by a French company. It measures pH, ORP and water temperature every hour; the salt version also tracks conductivity, which helps you keep an eye on 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 and comes with a 2-year warranty that includes the probes. The app anticipates changes in the water and only suggests a dose when one is needed.

Pros: personalized recommendations, a dedicated version for saltwater pools, no gateway to install. Cons: the most premium analyzer here; your Wi-Fi has to reach the pool. Best for: owners who want precise monitoring, including with a salt chlorine generator.

2. iopool EcO: the easiest to live with

The iopool EcO is a floating puck about 9 in (22 cm) long. Three sensors measure temperature, pH and ORP, and the data goes out roughly every 15 minutes through a Wi-Fi gateway placed between the house and the pool. The battery isn’t rechargeable: it’s designed to last about two years with no charging or calibration, after which you replace the module. The free app, with no subscription, calculates how much product to add.

Pros: no charging or calibration, a gateway that improves range, broad compatibility. Cons: the module has to be replaced after about two years; no salt-level tracking. Best for: a first step into smart pool care, and the best value of the bunch.

3. Zodiac eXO iQ: automated saltwater treatment

The Zodiac eXO iQ is a salt chlorine generator with built-in Wi-Fi, designed for pools of up to about 42,000 gallons (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 ORP reading. From the manufacturer’s app, you can follow water quality and control other compatible equipment such as the pool pump, heater or lights. Zodiac states a 3-year warranty on the cell, and an eXO iQ LS version is designed for low-salt water.

Pros: truly automated treatment, one place to control your equipment, widely supported by pool professionals. Cons: saltwater pools only; it gets plumbed into the pool’s circulation system, ideally by a pro. Best for: saltwater pools, or owners ready to switch to salt and stop adding 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 40 ft (12 m) long, with two active brushes and a multi-layer filter that opens from the top. Its 59 ft (18 m) cable has an anti-tangle swivel, the default cycle runs 2 hours and the MyDolphin Plus app starts and schedules cycles. Maytronics states a 3-year warranty.

Pros: no battery to manage, an easy-to-empty filter, a large dealer network. Cons: a 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 the floor and walls, it covers up to 3,875 sq ft (360 m²), navigates with ultrasonic sensors and is controlled over Wi-Fi or Bluetooth.

Pros: no cable, surface skimming, long battery life. Cons: a premium model, heavy to lift out of the pool, clarifier refills to buy. Best for: large pools surrounded by trees. Other cordless options are covered in our robotic pool cleaner comparison.

Variable-speed pumps: smarter filtration

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

Replacing a pump means working on the plumbing and the electrical panel: have it done by a pool professional or a licensed electrician, and check that it’s compatible with your filter and plumbing. If you keep your current pump, a programmable pump timer installed by a professional already lets you match run time to the water temperature.

Covers, alarms and safety

In France, every private in-ground or partially in-ground pool must have at least one safety device that meets a French standard: a barrier (NF P90-306), an alarm (NF P90-307), a cover (NF P90-308) or an enclosure (NF P90-309). Rules differ elsewhere, so check your local requirements. A compliant automatic cover can serve as that safety device, provided it’s closed and locked whenever the pool is unsupervised. Some motorized covers can be operated remotely or tied into a smart home system, but always keep the pool in sight while the cover opens or closes.

No equipment replaces adult supervision: keep children in sight whenever they’re near the water, even with an alarm or a cover. On the maintenance side, a cover cuts evaporation, holds in heat overnight and keeps out leaves and bugs, so you use fewer chemicals.

Where to start

1. A water analyzer: the device that changes day-to-day pool care the most, with no installation work. No more test strips and guesswork dosing.
2. A programmable robot: it takes over the most frequent chore.
3. Filtration: a variable-speed pump or temperature-based scheduling, best planned for when your pump is due for replacement.
4. Automatic treatment: a salt chlorine generator and pH control, if your pool is already saltwater or you’re ready to switch.
5. Cover and lighting: a bigger project, often done during a renovation.

Mistakes to avoid

• Buying an analyzer that doesn’t match your sanitizer: with some brands, the salt and chlorine versions aren’t interchangeable.
• Ignoring Wi-Fi at the pool: without a stable connection, the alerts never arrive.
• Relying on ORP alone: it indicates sanitizing power, not an exact chlorine level. An occasional manual check (free chlorine, stabilizer, total alkalinity) is still worthwhile.
• Forgetting the probes in winter: take the analyzer out at the end of the season and store it the way the manufacturer recommends.
• Confusing automation with safety: an app replaces neither a compliant safety device nor keeping an eye on children.

Installation and electrical safety

Anything plugged in near water should be on a circuit with GFCI (ground-fault) protection. A robot’s power supply should sit away from the pool, out of reach of splashes, at the distance given in the manual. Salt chlorine generators, pumps, pump timers and underwater lights are wired at the pool equipment area: have that work done by a licensed electrician or a pool professional. Never swim while a robot is running.

The bottom line

To make a pool smart without any construction work, start with a water analyzer: the Ondilo ICO Pool V2 for the most complete monitoring, especially with saltwater, 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 puts control of your equipment in one place.
