While both models are premium robotic pool cleaners, The Dolphin Oasis z5i is the newer option offering slightly more convenience because it comes with Bluetooth capability and can be controlled with your smartphone via the MyDolphin app. With the app’s scheduler, you can schedule weekly cleanings (for setting cleaning cycles and times) to remote control options, it’s certainly good to have.

While the Dolphin Premier can be purchased with an optional wireless remote controller, managing the Oasis z5i is better with your smartphone! The Dolphin Premier Robotic Pool Cleaner is priced fairly decently and offers similar technology to the Dolphin Oasis z5i.

The Robotic pool vacuum is designed with top load filters which are easily accessible rather than having to load them from the bottom as with the Premier. The Oasis z5i boasts 2 extra-large filter compartments for maximum efficiency as opposed to one oversized debris bag as featured on the premier.

The Oasis z5i is manufactured with the savvy Dual Commercial Drive Motors and its 360-degree turning mechanism working together with the frontal and rear split brushes offer superior cleaning capability.

The brushes on an Oasis z5i are passive, meaning they aren’t connected to any drive motors. Instead, they spin whenever they come into contact with the pool surface. The forward/ reverse motion of the robot is what causes these brushes to spin. They are decent enough at dislodging sand, and other smaller particles.

Not just that, but the excellent navigation system (SmartNAV 3.0) only helps to guide the robot on its cleaning path, ensuring that all the dirt and grime in its way is cleared away without hassle.

Other features, like wall climbing, high suction power, superior filtering capabilities, and dual scrubbing brushes all make it even easier for your robotic pool vacuum to get the job done. The bot is great for all types of ground pool surfaces from pebble tech to vinyl-lined pools.

If you are looking to save a little bit more on your robotic pool cleaner, then you should opt for Dolphin Premier. It sports similar features and specifications as the Oasis z5i, so you’re not missing out on too much. If you are a sucker for the latest technology, then the Oasis z5i is a definite keeper! 

It is worth noting that these models, as well as a few other ones from Maytronics (like the dolphin Sigma, for example), all offer excellent potential for a fair price. For this reason alone, we’d suggest that you consider the Dolphin Oasis z5i, Dolphin Premier, and perhaps even the Dolphin Sigma.
