The Best Robotic Pool Cleaner [Product Comparison]

Manually cleaning your pool is never an easy or simple task. It’s time-consuming, it’s physically demanding, and it’s easy to get wrong if you don’t know what you’re doing.

By automating your pool cleaning with a robotic pool cleaner, you can reduce the time and effort required to keep your pool sparkling. Instead, you can spend that time saved cooling down, exercising, and having fun in your pool.

What is the Best Robotic Pool Cleaner?

The best robotic pool cleaner is the one that gets the job done. The best robotic cleaner for you and your pool is going to depend on a few things.

Before you start comparing products, ask yourself the following questions:

How big is your pool?

The length of cable connected to your robotic pool cleaner is a fixed length and dictates how far it can reach. If your cord is too short, you may have to move your power supply or risk the power supply falling into the water. 

The power supply must be 4m away from the side of your pool any time the robotic cleaner is in use.

Tip: Factor in the depth of your pool, as well as the length, when calculating how large your pool is.

What kind of pool linings and surfaces do you have?

The type of pool surfaces you have will determine what kind of scrub brushes your robotic pool cleaner has. 

Some cleaners have Combined Scrub Brushes for coarse bottoms like quartz, pebble, or granite:

Dolphin M500 Combined Brush

Others have Wonder Brushes, for smooth surfaces like fully tiled pools, fibreglass, or vinyl:

Dolphin M400 Wonder Brush

If the brush type on your cleaner isn’t matched to your pool’s surface, then the cleaner may not climb the walls as it should, and you may not get the best life out of the brushes on the cleaner.

 

What shape is your pool?

Some robotic pool cleaners are better at getting into hard-to-reach corners, and others are better suited to uniquely shaped pools.

Tip: If your pool is narrow (less than 2.5m wide), we recommend a Dual drive cleaner to ensure that the cleaner can better clean the pool.

 

What kind of clean do you want?

All robotic pool cleaners clean the bottom of your pool—some can’t clean water lines, and some don’t climb walls. The more capabilities your robotic pool cleaner has, the less you will have to clean manually. Knowing what cleaning you want to automate will help decide what model you purchase.

 

What is your price point?

A robotic pool cleaner is an investment, that being said, cleaners with all the bells, whistles and features are going to be more expensive than basic models.

 

What features do you want your pool cleaner to have?

Do you want your robotic cleaner to climb walls? Scrub the waterline? Do you want an intelligent robotic cleaner with CleverClean(™), or a cleaner that’s able to connect to the MyDolphin(™) app, so you can control your robotic cleaner from your phone? 

The more features your robotic pool cleaner has, the less manual cleaning you’ll have to do, and the price will reflect that. 

 

What kind of debris generally accumulates in your pool?

The type of filter system on a robotic pool cleaner will help determine if it’s right for the type of debris you generally see in your pool. 

Fine dirt and sand? Leaves and seeds, as well as dirt? A dual filtration system is capable of handling both large and small debris and might be right for you.

Robotic Pool Cleaners: FAQ’s

How do robotic pool cleaners work?

A robotic pool cleaner operates like an underwater vacuum: it has internal electric motors that propel it forwards and backwards as well as providing the suction to trap leaves and dirt. 

A robotic pool cleaner doesn’t put any extra stress on your pool filters, in fact, it alleviates some stress from the system because it cleans your pool separately from the filtration systems you already have in place. 

How long do robotic pool cleaners last?

The average lifespan of a robotic pool cleaner varies depending on how often you use it, and what maintenance you perform on your machine. 

Most people find that their robotic pool cleaner lasts anywhere from 3 to 5 years or longer. Longevity can be added with consistent basic maintenance and the occasional part replacement. The oldest cleaner we’ve seen is still running after over 15 years!

Tip: Rinse the filters and clean out the debris basket after every use to extend the life of your robotic pool cleaner. This will also help you keep track of any parts that display more wear and tear, and organize a replacement before it breaks or the failing part puts any extra stress on your machine.

Prolonged exposure to pool chemicals and chlorine can shorten the life of your robotic pool cleaner, so following the manufacturer’s instructions for care and storage will help make it last longer.

How much do robotic pool cleaners cost?

Robotic pool cleaners are an investment, and their price reflects that. If you’re hedging at the price, think about how long you spend manually cleaning your pool.

It might help to compare the outright cost of a robotic pool cleaner and how long you can expect to have it (3-5 years, often longer), to what you’d pay to have someone clean your pool. 

All the cleaners listed above are Climate Care Certified, having proven themselves to save you both power and water as well as reducing your overall carbon footprint while saving you money.

Where can I get my robotic pool cleaner repaired?

Check your warranty. All robotic pool cleaners come with a manufacturer’s warranty. Depending on the model, your warranty can be anywhere from 12 months full and 24 months limited warranty, to 36 months full warranty. 

Some retailers offer the option to extend the warranty, and in the case that your warranty has lapsed, bring your robotic pool cleaner back to where you purchased it.

Tip: Robotic pool cleaners are designed to operate underwater, running it while it’s out of water will void your warranty, and put stress on the machine that can cause it to break. 

Why don’t they all climb walls?

Some robotic pool cleaners are designed specifically for above-ground pools – or maybe you only want to clean the floor of the pool – it’s your choice. The water that jets from the top of the floor-only cleaners will also help to keep the walls clean, as well as improving the overall water circulation in the pool.

What are the ideal operating temperatures for my Dolphin pool cleaner?

Between 6 degrees C and 35 degrees C is ideal for your robotic pool cleaner. That being said, it is possible to use it outside those temperatures, but you may not get the desired clean you want, and you could potentially damage the integrity of the machine by consistently using it outside the recommended temperatures.

Can you leave the power supply out in all weather?

The power supply is designed to be water-resistant, not waterproof. Cover in the case of inclement weather, and don’t submerge the power supply in your pool. 

Cleaning pools is not a small job. With a robotic pool cleaner as a part of your pool cleaning supplies, you can spend less time worrying about the physical demands of scrubbing and vacuuming, and spend more time enjoying your pool.
