Dolphin Oasis Z5i Review | Outstanding Robotic Pool Cleaner

Dolphin Oasis Z5i review

Fantastic cleaning power with simple operation

The Dolphin Oasis Z5i pool cleaner is one of Maytronics premium models, and as such, comes with loads of great features and certainly earns its place among the best robotic pool cleaners on the market. For a pool size up to 50 ft, there’s no doubt that this is the best of the best, with its high-end cleaning technology, ultra fine filter cartridge system, and much more.

If you have an in-ground pool (up to 50ft, the maximum pool size for this model) then keep reading, this may well be the pool cleaning robot for you. Much cheaper than hiring a pool boy, this robot is well worth looking into if you want a good quality device.

How the Z5i robotic pool cleaner works

The Dolphin Oasis Z5i pool cleaners comes with packed with a power supply which you plug into an outlet, and then the robot to the supply. Once connected, it is as simple as dropping it in and letting it go to work.

When in the pool, the robotic pool cleaner uses Maytronics patented CleverClean Technology to map your pool and work out the most efficient way to clean before setting to the task of filtering the dirt and debris from your pool.

The sensors will detect the dimensions of your pool and estimate with precision the amount of time it will take to clean it. thanks to their efficient technology and advanced navigation software, these robotic pool cleaners also spot the areas where dirt is hiding and tries to balance the areas that need a more thorough clean, whether that’s on the pool floor, walls or waterline.

Once underway, the Dolphin Oasis Z5i moves across the pool floor while on its belly, the powerful scrubbing brushes dislodge all the dirt and debris in the pool ready to be sucked up into the filters.

But these robotic pool cleaners won’t just do the floor, as they’re also able to climb the sides to ensure that the walls are kept clean and will even do submerged steps and waterline cleaning too.

Anti-tangling swivel cable

The My Dolphin app The app can be used for status updates, schedule programming and spot cleaning control. You can easily set it to clean early in the morning or late at night so your pool is always ready when you want it to be.

Ease of use

A big question that many pool owners looking to buying an automatic pool vacuum is whether it will be easy to use and if the instructions of use are straightforward.

As we have already alluded to, there should be no concerns with this particular pool cleaner. The Dolphin Oasis Z5i robotic pool cleaners comes pre-assembled and once you receive your package, all you need is to pull it out of the box, plug it in and lower into the pool.

Cleaning performance

Overall the Dolphin Oasis Z5i receives a lot of great feedback from many users across the internet. One particular buyer with a large swimming pool notes that it is very cost effective as she no longer has to hire pool cleaners and unlike manual cleaners, you don’t have to run your pump.

The commercial motors, split brushes, Bluetooth connection, warranty, and large filters are some of the features that impress when it comes to performance. However, there is some feeling that the Bluetooth connection is typically limited to a small area.

Perhaps, for the price, Wi-Fi would be a better option since you can track the pool robot even inside the house and can start the cleaner even when far from the pool. All in all though, there’s a lot that make the Dolphin Oasis Z5i robotic pool cleaner worth purchasing.

Reliability

The inbuilt software of the Z5i ensure that it learns and understands the shape and size of your pool leading to the most efficient cleaning routes. This, in turn, results in less wear and tear on the device and hopefully a longer life span.

However, the pool cleaners lifespan can also be affected by other factors such as the size of the pool and the amount of debris it is cleaning regularly. If you have a large pool surrounded by trees that regularly drop debris, then the machine will have to work harder and maybe lead to an increased chance of breakdown.

As it is still a relatively new model, it is hard to honestly know how long it can be expected to reliably operate. But Maytronics have a great product catalog and their Dolphin pool cleaners have always been reliable, there is no reason to think the Dolphin Oasis z5i robotic pool cleaner will be any different.

With proper upkeep and maintenance, the pool robot should be working for many years.

FAQs

Conclusion

The Dolphin Oasis Z5i is an incredibly useful device that will keep your pool clean and drastically reduce (but not totally eliminate) manual pool maintenance chores.

If you’re looking for good coverage, durability and efficiency, this may just be the best robotic pool cleaner for you. Say goodbye to algae, dirt, debris, slimy floors, and walls in your pool and with regular maintenance, it should last up to eight years.

If you are looking forward to making a considerable investment in your swimming pool, this is arguably the best robotic pool cleaner that will give you value for the money.
