However, Maytronics puts out a lot of different robotic pool cleaners. If you go onto their website and look at their catalog, you will find that there are a wide variety of different choices available to you.

Finding the right robotic pool cleaner, from Maytronics, can be a bit difficult when you consider that fact.

That’s why we’re looking at one of Maytronics best robotic pool cleaners. The Dolphin Oasis Z5i.

Before we get into what it is, that makes this a very special robotic pool cleaner, and how it can benefit you, let’s go over what a robotic pool cleaner actually is, as a refresher.

What Is A Robotic Pool Cleaner And What Does It Do?

Robotic pool cleaners are simple devices. They go into your pool, and then, through the use of sensors that are specifically designed for cleaning pools and working underwater, they begin to create pathways.

These pathways enable the robotic pool cleaner to efficiently, and methodically, clean the entirety of your pool. Each sensor can detect the size of your pool, how long it will take to clean, and the spaces and spots that are the dirtiest and in need of the most cleaning.

During the cleaning process, brushes are used. These brushes are located on the bottom of the device itself, and the brushes are then combined with suction. So, dirt and debris is brushed – which dislodges it – and then sucked into the pool cleaner.

When the robotic pool cleaner is done cleaning, it exits the pool on its own. Then, you simply take the bag of debris and empty it.

What Can The Dolphin Oasis Z5i Do For Me?

Let’s start with a few basic pieces of information. If you have a pool that is less than fifty-feet, then you’re off to a great start. The Z5i can’t clean pools that are larger than fifty-feet that well.

With that out of the way, the Z5i is a very convenient and easy to use robotic pool cleaner. Much of this comes from the app, which enables you to control the vacuum using your smartphone, without needing to use a remote control or some other device.

You don’t have to control the vacuum, but for spot cleaning, it is indispensable.

Along with that, there’s the fact that you have access to a cable that has been designed to swivel. This prevents tangling, and it gets rid of a lot of the hassles that often come with these cables. That, and the cable is very durable, so it’s less likely to get damaged.

Finally, in terms of convenience, you only need to put the robotic pool cleaner into your pool, and then press a single button. Once you do that, the device starts to clean.

However, the Z5i does weigh 31 pounds. So, it’s a heavier device, and that may make taking it to the pool a bit annoying.

Of course, none of this talks about how the device cleans. Fortunately, it cleans exceptionally well, and that is thanks to a couple of distinct features.

With bad sensors, a robotic pool cleaner just isn’t going to work very well. With the Z5i, there are sensors in place that allow for specific maps to be created, on the fly. And, in alignment with that, there is a turning system that enables the Z5i to turn at 360-degrees with incredible ease.

Whether you want to clean the floors of your pool, the walls of your pool, or even the waterline, the Z5i has been designed to do just that. You can clean all of those things with immense ease since the brushes have been designed to clean those spaces in the pool.

Using dual-scrubbing brushes, dirt and debris are easily taken care of. These are strong and durable brushes that work exceptionally well.

You have fine and ultra-fine cartridge filters. These are simple filters that are easy to use and work great for things like big and small debris, leaves, dirt, etc.
