Review Summary

Dolphin’s Oasis z5 is best described as a pool-cleaning tank, a fear-inducing weapon to spread terror among the dirt, grime, and algae that turns your pool linings green and makes using it less than fun. It’s big, heavy, but it also powers wages a relentless war to save you a lot of time maintaining and cleaning your tool, which will leave you more time to enjoy it.

As you can expect, it’s also expensive. It will be the most expensive weapon in your arsenal but operates with efficiency and thoroughness that you might consider your investment in it — especially considering how much money it takes to build and maintain a pool in general — well worth what you spend.

Tracks and brushes

Like a tank, the Oasis z5 operates on tracks, not wheels. The tracks help keep it gripped to the sides of the pool while spinning brushes on the same drum that power away grime and algae in its path. It also has a dual-track system so that it doesn’t turn in wide sweeps but can turn, appropriately enough, like a tank. That means delivering its serious cleaning with sharper turns.

Access filters from above

Speed the amount of time you spend time maintaining and prepping your pool cleaner for action from above. Previous models required that you access filters and other spaces from below, which creates a lot of inefficient work. The Oasis z5 permits access from above, which makes for fast, time-efficient cleaning.

CleverClean scanning

Odd-shaped pools aren’t a problem from the Oasis z5’s CleverClean scanning that can make a map of your pool and internally sketch out the best, most efficient way to clean it. This means it also works well with pools with obstacles built into them.

Dual-motor efficiency

The Dolphin Oasis z5 comes with two onboard DC motors. One governs propulsion and one drives cleaning. This means dedicated power for both functions, which translates into improved performance. But it also means more efficient operation, because the DC motors operate with less energy at traditional AC boosters. When you figure in the CleverClean scanning, that means it can clean your pool quickly literally for pennies.

What the Users Say

People who bought the Dolphin Oasis z5 were generally very happy with it. They found it to be an effective, thorough pool cleaner that, although expensive, was worth the cost all things considered. In particular, it was called a superior performer compared to other models of pool cleaners, which didn’t do as thorough a job in cleaning up pool floors and walls. In particular, people who bought this were pleased that they had much less work to do supplementing what it did. For pool cleaners in general, this is a pretty substantial issue, so it’s kind of difficult to say just what a plus this is.

For a unit that costs so much compared to other pool cleaners, very few people commented on what the Dolphin Oasis z5 costs. Considering that its price can reach to a couple of thousand dollars, that’s pretty significant. On the other hand, pools themselves are significant investments, so it’s possible that when it comes to pool cleaners that people who’ve already shelled out that kind of money are willing to eat another pricey gadget.

Some people, on the other hand, reported that it got caught on the main drains. This happened often enough that it can’t be written off to one or a small handful of lemon units. Either the instructions aren’t clear enough for people to use it, or there’s some kind of flaw in the design that needs addressing. For the price, it’s an actual issue.

If you spend enough time looking at and using robotic pool cleaners, this is a pretty consistent complaint. It is one of two, in fact. There is a tendency to get stuck on drains and there is a general dissatisfaction with the level of clean it delivers based on the amount of money it costs. Both, in fact, apply to the Oasis z5.

But in general, users were pretty satisfied with its performance. It was considered a reliable little tank of a cleaner that goes to work and cleans everything. It’s pricey, but a time saver. Not just in terms of raw time cleaning the pool, but in the amount of time that the pool owner had to spend maintaining it.

The Dolphin Oasis z5 is a tank among pool cleaners. It’s big, unstoppable and designed to power away dirt and grime from the floor and sides of your pool. It has features intended to allow it to work while you find other ways to spend your time, making it a time saver not just in terms of direct operation but for the pool owner, tool. Owners will also like that they can access the filters from above, making cleaning it out a faster, more efficient process.

This comes at a cost, however. A bit cost. This is a very, very expensive pool cleaner, even for a robotic pool cleaner. It’s also really heavy, which means that getting it in and out of the water will be a special chore.

The question is whether that cost can be justified by the performance. Installing a pool and maintaining it are both by themselves very expensive propositions, and this is context worthwhile keeping in mind when assessing that.
