A pool cleaner robot might sound like something from the future but in reality the technology is here and it’s pretty amazing to say the least. Any pool owner will tell you that keeping the pool sparkling clean is the hardest part of owning a salt water pool and that’s where automatic cleaners can come in really handy. If you want to spend less time keeping your pool clean and let a robotic pool cleaner do the work while you aren’t even around you’ll want to keep reading.

Best Robotic Pool Cleaner for Salt Water Pools

​We’ll look at the best automatic pool cleaners for salt water pools, giving the pros and cons of each and identify the right users for the model.

Budget Option

Dolphin Nautilus Plus Robotic Pool Cleaner
The Dolphin Nautilus Plus Robotic Pool Cleaner is an advanced, easy-to-use robotic pool cleaner that is designed to scrub, vacuum and filter in-ground residential pools of up to 50 ft. in length.

Maytronics has launched two versions of this particular robotic pool cleaner – The Dolphin Nautilus CC and the Dolphin Nautilus CC Plus. Both models have almost similar features with just a few differences between the two. The main point of difference lies in the cycle time. The Nautilus Plus has a shorter cycle time of 2.5 hours as compared to 3 hours of the Nautilus.

Its top loading filters are easier to remove and clean than the bottom loading filters of the old Nautilus model.

The Dolphin Nautilus CC Plus has an anti-tangle swivel cable, but a caddy is not included. It does not have a remote control and it is not compatible with the MyDolphin Bluetooth app.

This internet-only model is covered by a 2-year limited warranty. The plastic parts, power supply, cable and motor is covered for 24 months. The brushes, tracks and filters are not under warranty.

The Dolphin Nautilus CC Plus is a pool-cleaning machine. Literally. A robotic pool cleaner, you set it up and set it loose. The Clever Clean system uses onboard sensors to map an optimal path through your pool to maximize its own efficiency. It can clean an average pool in about two hours.

Once in operation, the sensors can also detect obstacles in the bottom of your pool, avoid them and return to the charted path without very little interruption in its schedule.

Some robotic pool cleaners would cost you an arm-and-a-leg to do this, but the Dolphin Nautilus CC Plus does this at the price of a top-end pressure-side pool cleaner, without the few hundred dollars’ extra expense for a booster pump.

Dolphin Oasis Z5i Robotic Pool Cleaner
The Dolphin Oasis Z5 is one of the latest models produced by the company. Its overall performance is excellent and its advanced features will take your pool cleaning to the next level.

The Z5i’s cleaning ability is on par with what you’d expect from a pool robot of this price.

It scrubs and vacuums the entire pool, removing algae, sand, leaves and all kind of debris. It easily replaces your pool boy or pool cleaning service.

If anything, it cleans better than a human. It’s also much better than traditional suction or pressure side automatic cleaners.

We all want the best in life and so as with the products, we want to own. This robotic pool cleaner is almost perfect and when it comes to ease, this is the one we recommend.

Did you encounter serious trouble to clean your pool in traditional ways? Are you looking for the best and trouble-free pool cleaner? Then the Dolphin Oasis Z5i Robotic pool cleaner is one of the best performing robotic pool cleaners.

Dolphin Premier Robotic Pool Cleaner
The Dolphin Premier is an advanced residential pool cleaner made by Maytronics, the world’s leader in robotic pool cleaning technology. Packed with high-tech features, the Premier has a lot to offer, including Maytronics’ excellent SmartNav mapping system. It’s programmable, too, and can be run daily, 2x per week or 3x per week.

It comes with a few quirks, however. The unit is heavy, so lifting it out of water may be hard on some. And, it’s not the best at cleaning steps.

In terms of raw cleaning potential, there are few pool cleaners — even robotic pool cleaners — that can match the performance of the Dolphin Premier. Its four-media cleaning options make this perfect for sweeping up the grit of a summer windstorm and autumn’s falling leaves with a quick swap-out of a filter.

It also comes with advanced controls that allow it to chart its own cleaning course to work quickly and efficiently. There are good reasons why the Premier is considered Dolphin’s top-shelf pool cleaner.

It’s only predictable, then, that it will cost you a pretty penny. This one is expensive, even allowing for the fact that inground pools are generally top-dollar investments. Its manual operation mode is also less than desirable.

Dolphin sank its best efforts into making this a high-end robotic pool cleaner to the detriment of its manual mode. Then again, you’re not shelling out this kind of money for a pool cleaner that requires that you do a whole lot of work.

Saltwater Pool Maintenance

Saltwater in-ground pools are installed with a poolside skimmer box, accompanying suction pump and filter, automatic chlorinator and sand filter.

To ensure the pool is always kept sparkling clean and free of leaves, small sticks and other debris, we lashed out and purchased the best robotic pool cleaner on the market.

All we needed to do now is sit back or should I say, jump in and enjoy our new pool and let the high-tech equipment we have purchased look after it for us!

Not quite! There are few things you need to be aware of to ensure the pool is well maintained, continues to look sparkling clean and remains healthy to use.

How to keep your pool looking clean

Health and cleanliness are two crucial factors in owning and using a home pool. But relying on the pools filtration and filtering systems alone is not enough.

To ensure the water in the pool is always clean and safe for you and your family, here are some tips and regular safety practices.

Pool Water Levels

During the hot summer months, water evaporation causes the pool water level to drop more than at any other time of the year.

Therefore, daily checking of the pool’s water level is an important maintenance routine.

Low pool water levels can affect the performance of the pool’s vacuum suction, filtering and chlorination systems and can significantly increase operating noise levels. Besides, the constant loud sucking, squeaking sounds can drive the neighbors crazy.

After heavy rain, the pool water level will rise.

Usually, this not a major problem as all inground pools should have an overflow hole on one side of the pool wall.

This hole is designed to drain water off (when it reaches this level) and away from the pool.

However, sometimes when there’s torrential rain, the overflow hole may not be large enough, and the water level in the pool will rise to the very top and flow over.

This needs consideration when choosing the location of your new pool.

Pool Cleaning Equipment

All pools require regular cleaning to remove dirt, leaves and other debris that always seems to collect in the pool.

Factors that need to be considered when determining the method and pool cleaning equipment you may need to ensure your pool is kept clean and healthy are:

Pool Type – in-ground, above ground, salt or fresh water
Size and capacity of pool
Pool environment (dusty, sandy, near the ocean, surrounded by trees and plants?)
Type of filtration system used
