Best pool cleaners: professional analysis and expert guide

Keeping your pool water crystal clear is not only a matter of aesthetics, but also of health and safety. Leaves, dust and organic debris can accumulate at the bottom, promoting the growth of bacteria or algae. That’s why having a good pool cleaner is essential. But how do you know which one is right for you? In this guide, we will analyse the best pool cleaners, their types, advantages and what to consider depending on how you want to use them, whether in a public pool, a small pool or even in professional facilities.

Types of pool cleaners: which one to choose?

Before choosing a specific model, it is important to understand the differences between the types of pool cleaners:

• Manual cleaners: these require physical effort, as they are connected to the filtration system and are operated by the user. They are economical, but less practical.
• Hydraulic cleaners: these work by suction from the filtration system itself. They stand out for their simplicity and good performance in small and medium-sized pools.
• Electric cleaners: these are autonomous, plug into the mains and work independently. They offer more power and usually include brushes and intelligent navigation systems.
• Professional heavy-duty pool cleaners: also electric, these are specially designed for public or large pools, combining durability, programmable operation, efficiency and advanced cleaning cycles. 

Comparison of the best pool cleaners in 2026

In 2026, technological innovation will continue to set the trend. Manufacturers have opted for increasingly autonomous robots with WiFi connectivity and mobile applications that allow cleaning to be programmed and monitored in real time.

Frequently asked questions about pool cleaners

What is the best cleaner for small pools?

For a small pool, the recommendation is usually a hydraulic cleaner or a compact electric robot. These devices are lightweight, easy to use and sufficient to keep the water in perfect condition without overspending.

What is the difference between a hydraulic and an electric pool cleaner?

Hydraulic pool cleaners use energy from the pool’s filtration system: they are more economical, but less autonomous. Electric pool cleaners, on the other hand, work independently, with programmable cycles and better cleaning capacity on walls and steps.

How often should a pool cleaner be used?

The frequency depends on the use and location of the pool.

• In a public pool, it is best to use it daily.
• In residential pools, it is recommended to use it 2 to 3 times a week, although in summer or when it is very windy, it may be necessary to use it more often.

How long does an electric pool cleaner last?

It all depends on maintenance, the quality of the model and the frequency of use. Keeping the filters clean and storing it in a protected place will extend its useful life. 

Is it worth paying for smart navigation with obstacle detection?

Yes, to extend the useful life of the product, as it prevents collisions with walls and other physical elements in the pool, resulting in less wear and tear on the pool cleaner’s mechanics.

Conclusion

Choosing the best pool cleaner is not just a question of price, but of analysing your specific needs: pool size, frequency of use and desired level of automation. From a state-of-the-art Zodiac electric pool cleaner to simpler options for small pools, there is a model to suit every need.

Investing in a good cleaning system not only improves the swimming experience, but also extends the life of the pool and ensures healthier water.
