Even though the Dolphin Premier also supports remote operation, it doesn’t come with the remote controller; you will have to purchase it separately.

2. Design and Aesthetics

In the second round, we compared the design and aesthetics of the two pool cleaners. As a buyer, you definitely want a lightweight pool cleaner with a small footprint. Besides, it’s essential to be in a position to identify the two pool cleaners from their aesthetics. So, which model wins this round?

Oasis Z5i Design
The Dolphin Oasis Z5i boasts a sleek design. Finished in blue, black, and grey, the cleaner measures 23.23 x 19.76 x 14.33 inches and weighs 24lbs. While it may not be the lightest robotic pool cleaner we have tested, it has a convenient carry handle that makes it easy for pool owners to drop it inside the pool. Lifting it out of the pool is also easy.

Dolphin Premier Design
The Dolphin Premier also has a stylish design. It is also finished in three colors, black, blue and grey. Regarding the dimensions and weight, the Premier measures 23.5 x 19.5 x 14 inches and weighs 20.3lbs. It also comes with a carry handle that comes in handy when lowering the cleaner into the pool and pulling it out.

verdict

As far as the design goes, it’s hard to call a winner because the two pool cleaners have almost the same dimensions and weight though the Dolphin Premier is lighter. In terms of aesthetics, they are both sleek pool cleaners.

3. Assembly and Installation

Unless you are a handyman, you definitely want a pool cleaner that won’t stress you to assemble it once it’s out of the box. So now, the big question is, which of the two Dolphin robotic pool cleaners is easy to get started with?

The Dolphin Oasis Z5i is easy to set up and doesn’t require any additional accessories, for example, hoses or a booster pump to operate. All you need to do is plug it into a power outlet, drop it into the pool, and you are good to go.
The Dolphin Premier is also a user-friendly robotic pool cleaner. Here again, you don’t need any additional accessories as it’s a single-button plug-and-play inground pool cleaner.
verdict

In this contest, it’s also hard to call a winner as both robotic pool cleaners are already assembled and don’t require any additional pool accessories to run. However, while they both feature a single button and have a plug-and-play design, the Oasis Z5i tags along with several sophisticated features that give users better control of the robotic cleaner.

4. Pool Type

As you may be aware, there are two main types of pools, inground and above ground. Besides, there are pools of different sizes and shapes and, importantly, different materials. Now, when it comes to selecting a pool cleaner, you need to make sure it’s the right fit for your pool. In this segment, we have analyzed the two Dolphin pool cleaners to determine what type of pool each is designed for.

Dolphin Oasis Z5i in inground pool
The Dolphin Oasis Z5i robotic pool cleaner is designed for inground pools only; you can’t use it in above-ground pools. When it comes to pool shape and size, the Oasis Z5i has a 60ft anti tangle cord and can handle 50ft pools of any shape.

Lastly, on the pool surface, it is suitable for all pool surfaces, including gunite, concrete, vinyl, fiberglass, you name it.

Dolphin Premier in inground pool
The Dolphin Premier is similar to the Oasis Z5i when it comes to the type of pools it’s designed for. It’s also an inground robotic pool cleaner with a 60ft power cord and can handle pools of up to 50ft regardless of their shape.

As for the pool surface, the Premier will also handle all pool surfaces, including fiberglass, gunite, concrete, and vinyl, among others.

verdict

Both Oasis Z5i and Premier are inground pool cleaners that can handle up to 50ft pools. They are also ideal for any pool shape and all pool surfaces. However, the Dolphin Z5i has the upper hand when cleaning irregularly shaped pools because of the updated navigation and mapping system, so we feel it deserves the crown in this round.

5. Cleaning Orientation

Next up is the cleaning orientation. Here, buyers need to be aware of where the robot they are about to purchase cleans. Definitely, you want to go for a model that offers comprehensive cleaning, from the pool’s floor to the walls, waterline, and even the water surface. So, which of the two Dolphins is the best in terms of cleaning orientation?

Dolphin Oasis Z5i Cleaning Orientation
The Dolphin Oasis Z5i can clean the pool’s floor thoroughly. It picks up all kinds of dirt. Besides the pool’s floor, it is designed to clean and scrub the pool walls and steps where algae and other grime stick.

What’s more? The Oasis Z5i can clean and scrub the waterline removing all stains and algae. For the record, the Oasis Z5i can’t clean any dirt and debris floating on the top, so you will have to find a solution for the dirt and debris that float on the water surface.

Dolphin Premier Cleaning Orientation
The Dolphin Premier, just like the Oasis Z5i, will also clean pool floors satisfactorily. It picks up all kinds of dirt that sink to the pool floor. It has also been designed to scrub and clean pool walls, steps, and the waterline leaving your pool sparkling clean.

Unfortunately, it doesn’t clean the water surface, so you will have to work your way out with a skimmer or a pressure side pool cleaner, for example, the Vac-Sweep 280, 360, or 380.

verdict

The Oasis Z5i and Premier are suitable for cleaning pool floors, walls, steps, and even the waterline. None of them can clean the water surface. That said, this round ends in a draw.

6. Performance

For optimal cleaning, it’s vital to ascertain the performance of the robotic cleaner. Under the hood, these cleaners pack a set of motors and other components that generate the suction required to suck dirt and debris. But then, performance varies from one model to another depending on the quality of components used. So, how does the Dolphin Oasis Z5i stack up against the Dolphin Premier in terms of performance?

The Dolphin Oasis Z5i comes with dual low inertia 24V motors. One of these motors drives the impeller, which sucks dirt and debris from the bottom of the cleaner.

Also worth mentioning is the fact that the Dolphin Oasis Z5i, unlike the old models, is energy efficient. Maytronics says it operates with 90% less energy while maintaining a steady 4500 GPH suction rate.

The Dolphin Premier is similar to the Oasis Z5i in terms of performance. Its impeller also sucks dirt and debris from the bottom of the unit and is driven by a low inertia 24V motor, though it also has two motors. We will explain the role of the other motor when assessing the robotic cleaner’s maneuverability. The Premier is also an energy-efficient robotic pool cleaner that uses 90% less energy than the old models without compromising the suction rate. For the record, the Premier has the same 4500 GPH suction rate as the Oasis Z5i.
verdict

As far as performance is concerned, there is no winner between the two. They come with the same energy-efficient motors that are highly energy-efficient compared to pressure and suction cleaners and have the same 4500 GPH suction rate.

7. Filtration System

The filtration system is another crucial consideration when choosing a pool cleaner. Here, there are two critical aspects to consider, the filters themselves and what they can filter One of the differences between Dolphin Oasis Z5i and Dolphin Premier is the filtration system. So, let’s find out how they compare.

Oasis Z5i Filtration System
The Oasis Z5i is designed with a top-load filtration system that makes maintenance a buzz. There are also two extra-large filter compartments that enhance efficiency.

When it comes to the filters, Maytronics designed this pool cleaner with high-efficiency filters that can capture all pool debris, including the fine debris to ultra-fine debris.

Dolphin Premier Filtration System
On the other hand, the Dolphin Premier is designed with a bottom-load filtration system that works just fine but can make maintenance cumbersome. But the good thing is that the Premier has interchangeable filters (multi-media, oversized leaf bag, fine, and ultra-fine cartridge) to enable pool owners to catch all debris sizes efficiently.

Unlike the Oasis Z5i, which has two extra-large filter compartments, the Premier comes with one oversized bag. There’s also a full bin indicator, a feature the Oasis Z5i lacks.

verdict

As far as filtration is concerned, it’s hard to call a winner as both models have pros and cons. The Oasis Z5i comes with two filter compartments and features a top-load design which makes maintenance easier as you don’t have to flip the heavy pool cleaner to access the filters, as is the case with the Dolphin Premier. On the other hand, the Dolphin Premier has interchangeable filters (multi-media, oversized leaf bag, fine, and ultra-fine cartridge) for customized cleaning and has a full bin indicator.

8. Brush System

The brush is an integral part of robotic pool cleaners. They are responsible for scrubbing stuck-on dirt, including algae and waterline stains. That said, it’s crucial to find out which model in this Dolphin comparison review has a better brush system.

Oasis Z5i Brush System
The Oasis Z5i has Dynamic Dual Scrubbing brushes with a split brush design, meaning they work independently of each other. These are passive brushes that don’t rely on the motors to turn. Instead, they rotate with the forward or backward motion of the pool cleaner.

One great feature of the Oasis Z5i’s split track brushes is that it facilitates zero-radius turning, thus enhancing maneuverability.

Dolphin Premier Brush System
The Dolphin Premier, on the other hand, comes with a single passive brush that stretches from one end to the other. It’s just as effective as the Oasis Z5i’s brush as it can scrub all kinds of pool stains on the pool floor, walls, steps, and even the waterline.

However, it doesn’t enhance the turning ability of the pool cleaner as the Oasis Z5i’s split track brushes.

verdict

As far as scrubbing is concerned, there is no winner between the two as their brushes effectively remove stuck-on dirt, grime, algae, and other dirt that stick on the pool floors, walls, and the waterline. However, we feel the Dolphin Oasis is the best choice as its brush gives the robotic cleaner better turning abilities.

9. Navigation and Pool Mapping

The navigation and pool scanning system is another vital consideration when choosing a robotic pool cleaner. As their name suggests, robotic pool cleaners operate independently, so they must have a system that enables them to find their way around the pool. Now, one of the main differences between the Oasis Z5i vs. Premier is the navigation and pool scanning system. So, which model wins this round? Let’s find out.

Dolphin Oasis Z5i Navigation
As a new model, the Dolphin Oasis Z5i relies on CleverClean Technology for navigation, pool scanning, and mapping. Unlike the older systems, CleverClean Technology uses advanced computer algorithms and a set of sensors to accurately scan your pool and ensure that every inch of the pool is covered, be it the deep corners of square and rectangular pools or at the bends of kidney-shaped pools.

With the Dolphin Oasis Z5i, you are guaranteed entire pool cleaning and, interestingly, in less time. On average, it takes the Oasis Z5i just 2.5 hours to get the job done.

Dolphin Premier Navigation
The Dolphin Premier in this comparison review also has an intelligent navigation system compared to models released almost 10 years ago. But then, the technology is different from the Oasis Z5i’s.

Maytronics equipped the Premier with SmartNav 2.0, which also uses sensors and advanced algorithms to scan the pool and choose the best path to follow, thus ensuring entire level coverage, from the pool’s floor to the walls and waterline. However, SmartNav 2.0 is not as precise as CleverClean, which is why the Premier’s cleaning cycle is 3 hours.

verdict

There’s no doubt the Dolphin Oasis Z5i is the best choice in terms of navigation and pool scanning. It comes with CleverClean Technology that scans and maps pools more accurately, guaranteeing 100% coverage regardless of the size of the pool or its shape. It also cleans faster compared to Dolphin Premier.

10. Maneuverability

In this section, we will analyze how the two pool cleaners compare in terms of maneuverability. While navigation is essential, the robot’s maneuverability is fundamental and can be the deal maker or breaker. So, how do the two pool cleaners move around your pool and climb walls?

The Dolphin Oasis Z5i doesn’t come with any wheels. Instead, it has rubber tracks. This is a major and significant shift as wheels mean extra maintenance requirements.

What’s more? Wheels don’t give the robotic cleaner the traction required to climb walls, but with the rubber tracks, the robot can move on the pool’s floor and climb the pool’s wall and steps swiftly. As mentioned earlier, the Z5i has two motors. While one motor drives the impeller, the other motor, also a low inertia 24V motor, drives the tracks.

Remember, this motor is also energy-efficient, so pool cleaning costs remain low regardless of how long you run the cleaner. Just to mention, the brush of the Oasis Z5i allows it to make 360-degree turns for optimal cleaning.

The Dolphin Premier also has rubber tracks instead of wheels. That means fewer moving parts and, consequently, lesser maintenance requirements. The rubber tracks on the Dolphin Premier are just the same as those you will find on the Oasis Z5i.

They are also driven by one of the two low inertia 24V motors as the other one drives the impeller.

The motor equipped in this robotic cleaner is also energy-efficient, so you won’t be hurting your wallet even if you run the pool cleaner daily.

verdict

It’s hard to say which model is best in terms of maneuverability as they both come with tracks instead of wheels, and the tracks are powered by the same low inertia 24V motor. But when you factor in the navigation and mapping systems of the two cleaners, i.e., CleverClean Technology vs. SmartNav 2.0, definitely the maneuverability of the Oasis Z5i is better. Still, the fact that the Oasis Z5i can make 360-degree turns makes it the best bang for the buck.

11. Controls

While the Oasis Z5i and Premier are both robotic pool cleaners, you need to give them commands to do their job. With that said, it’s important to assess the controls to know which model is more convenient. So, how do you control the Oasis Z5i and the Premier? That’s what this round is all about.

Dolphin Oasis Z5i Controls
The Dolphin Oasis Z5i has an easy-to-use power supply and a single button that makes operation easy. Besides, this is a connected model that comes with Bluetooth and WiFi compatibility for remote operation via the MyDolphin Plus mobile App.

Even though the app is clunky, it’s still a worthy feature as you can start or stop a cleaning session and set cleaning schedules at your convenience. In addition, you can manually control the robot from the app to clean specific spots.

Dolphin Premier Controls
The Dolphin Premier also has an easy-to-use power supply, so operating the robot shouldn’t be an issue. But then, it doesn’t come with a remote in the package though you can purchase the remote separately.

The remote gives you pretty much all the control options and settings. You can also control the robot’s movement using the remote.

verdict

As far as controls are concerned, the Dolphin Oasis is the best choice. Even though the Premier works with a physical remote, the remote is not included, so you will have to spend more to get it. On the other hand, The Dolphin Oasis Z5i can work with the mobile app available on Google PlayStore and Apple AppStore, so there are no more expenses.

12. Smart Features and Automation

In this smart home era, you definitely want a smart pool cleaner that allows you to automate pool cleaning and ultimately get more time to focus on other important things, and not pool cleaning. Fortunately, Maytronics has been on the frontline in making pool owners’ lives easier without compromising on the quality of pool water. In this section, we have assessed the different smart and automation features that these two pool cleaners tag along with.

The Oasis Z5i, as mentioned earlier, is a smart robot vacuum with several automation features. One of them is the Weekly Scheduler, and as the name suggests, it allows users to schedule the robot to clean every day of the week, every 2 days, or every 3 days.

Unfortunately, you can’t set it to clean on a specific day of the week or at different times on the same day. It’s also a connected model, so you can operate the robot cleaner remotely.

Unfortunately, despite being a top-of-the-range model, it lacks features such as cycle selector and delay mode.

The Dolphin Premier, on the other hand, is not a smart robotic pool cleaner, so you can’t enjoy the convenience of remote operation via the mobile app. The only option is to purchase a remote. But at least it has the Weekly Scheduler, so you can set it and forget about cleaning, at least for the entire week.

Just like the Oasis Z5i, you can set it to clean every day of the week, every 2 days, or every 3 days. But there is no option to select specific days.

The Premier also lacks essential automation features such as cycle selector and delay mode.

verdict

It’s hard to call a winner now that the two pool cleaners have the Weekly Scheduler and Weekly Timer. However, we feel the Oasis is a better shot now that you can set the Weekly Scheduler without necessarily bending on the power supply as you would with the Premier (it lacks a remote).

13. Warranty, Aftersales, and Parts Availability

In this last round of this Dolphin Oasis Z5i vs. Premier comparison review, we will look at the warranty and aftersales of the two robotic pool cleaners. Here, the target is a model with the longest warranty and, importantly, readily available replacement parts.

The Dolphin Oasis Z5i comes with a 3-year warranty that covers your pool cleaner in case it encounters a manufacturing defect within the first three years of purchase. But then, many brands and sellers out there don’t honor the warranty. Fortunately, Maytronics is a renowned brand that honors warranties despite the few complaints out there. Regarding replacement parts, they are in plenty and at affordable prices. When it comes to aftersales, it all boils down to where you purchase your pool, but Maytronics has reliable customer support that buyers can rely on when stuck.
The Dolphin Premier also tags along with a 3-year warranty. Now that it’s from the same brand as the Oasis Z5i, it’s safe to say that the warranty will be honored as long as it’s a genuine claim and the buyer has not voided the warranty. As for replacement parts, the Premier’s parts are also readily available and at fair prices.
verdict

Here, there is no winner as both models are from the same brand and are covered by the same warranty.

Wrapping Up

There you have it, folks, a detailed Dolphin Oasis Z5i vs. Premier face-to-face comparison review. As you have seen, these two models are pretty similar. They are both inground pools suitable for all pool types of up to 50ft. They also feature tracks driven by energy-efficient 24V motors.

But then, there are a few differences. The Oasis Z5i has better navigation and mapping and cleans an average pool faster. It is also a connected model that facilitates remote operation via the MyDolphin Plus App. Another advantage is that its maintenance is easier now that it has a top-load filter system, so there’s no need for lifting the unit to clean or change the cartridges. On the other hand, the Dolphin Premier is cheaper and has a much more efficient filtration system and a full bin indicator.

All said and done, the Oasis Z5i is the best choice if you are not on a budget, but if you are on a budget, the Dolphin Premier is also a worthy cleaner.
