Head To Head Review Analysis

The DX4 is a solid robotic pool cleaner. It did fall occasionally while it did its wall cleaning, and it took a while to conquer cleaning the underwater steps. Plus, the bag is no one’s favorite maintenance chore. However, it still cleans remarkably well and captures an impressive amount of debris. After its one cleaning job, the pool surfaces were spotless and the water was far clearer and brighter than before. You will definitely get what you pay for with the DX4. It’s priced affordably, but we wouldn’t say it’s a steal. It may have a few shortcomings, but none of them are deal breakers. Instead, it’s a durable and trusty robotic pool cleaner that has the power to make your life easier.


The Dolphin DX6 robotic pool cleaner is a good investment for any pool owner. Sure, it’s not perfect. But we wouldn’t consider its small flaws to negate its cost. Its dexterity underwater is impressive, and the way it actively scrubs and releases tough debris is worth our applause. Even though the filter bag can be frustrating to handle and clean, we can’t argue that it does its job incredibly well. If you’re ready to hand in your handheld pool brush for a machine that’ll do that hard work for you, the DX6 is a worthy option.

Great pool cleaner!

Kim -

I have a 28'x15' pool and it does a great job. I just push the button for the 3 hour cycle and I know it'll be perfect. It's usually already perfect after an hour... but I leave it go just to make sure it cleans all the sides. It easily climbs the walls up to the water line and it climbs up on stairs. It does have a remote, but I haven't had to use it.

33 Months Old & Still Going Strong

Robert Gardner -

My DX 4 is a great pool cleaner. I use it about once per week for its 2.5 hour cycle in my 50-foot by 26-foot pool, and my pool is cleaner than when I ran my Polaris every day for 3 hours per day.. I especially like the two different filter types, one with a very fine porosity. When the pine pollen is at its peak, I use the fine filters to help my sand filter keep the pool water sparkling.

Wonderful, efficient machine! It has made my pool cleaning 100x easier. It does a great job of getting fine sand/silt out. It requires very little effort for such a great return of help. It is easy to clean the filter bags.

Nice little robot!

It cleans nicely but I wish they would offer a trade discount for the new ones since they are so much easier to clean from the top.

cleaning the dx4

Joseph LaScala -

My dx4 cleans my pool well. Although it turns over on its back when cleaning the waterline. Also, I dislike cleaning the bag. My dx4 did not come with cleaning cartridges but a bag. This is like cleaning a dirty diaper. I don’t like it at all. that’s why I only gave it 3 stars

Power supply unit

Bruce Angner -

This is the 4th year for my cleaner. I have only used it on average of 10 times per year. The power supply unit went out this year and has to be replaced. The unit was kept inside when not in use and was never left out in the rain. I expected it to last a lot longer than this.

Maytronics Pool Cleaner

Bill M -

This is a vast improvement over the Maytronic Diagnostic Model. I love the fact that it has a remote control, and full bag signal. The cord doesn't get all twisted up, as they have installed a swivel. I am pleased with the unit and the seller provider timely responses to questions.

Awesome Pool Cleaner.

Adam Cochran -

The Dolphin DX6 does an excellent job cleaning our pool. We replaced it for another smaller Dolphin that lasted about 7 years. But the DX6 is much more powerful and does a better job scrubbing the walls and steps. We don’t really use the remote, but I guess it may come handy in some pools.

Sturdy and reliable

Danielle D -

I have used for a year and have been pleased with performance. Even though my pool is indoor this vacuum still picks up a lot of debris. It seems like it is well made. The ease of use far exceeds the manual vaccuum. I would buy again it is worth the investment.

We were ready to fill in the pool until we got our Dolphin

Mary B-J -

For several years we struggled with 3 different brands and styles of cleaners. Ready to give up and call the bulldozer, our dealer suggested the Dolphin. He said it was “a bit pricey,” but well worth it. He knew us well, so we trusted his recommendation. So happy we did!

A Real Work-Horse

Paul Zimmerman -

Our Dolphin DX6 does a great job cleaning our pool. Gets all the debris and filters the water too. In our opinion, this is the best robotic pool cleaner out there. Very energy efficient because does not use a booster pump or pool pump. Just plug it into a standard outlet. If it ever wears out, we will buy another! Highly recommend!

DX6 and relax!

Drew J -

The DX6 does an excellent job of vacuuming the bottom and sides of our in-ground pool via auto or remote control. Occasionally, it can get stuck on the protruding drains and therefore you should not leave it alone for long periods without taking notice of its movement. Sure beats constantly sweeping the bottom carefully towards the drains because it stirs up the dirt and redeposits it elsewhere. The DX6 is a great addition to the pool servicing. P.S. Danielle D’s pool is beautiful! To have that year round in this New England climate would be the ultimate. Beautiful pic!

I’ve used my Dolphin DX6 one season and about to start second. While putting great effort into cleaning myself, I cannot compare to the Dolphin. I will never be without one… I usually mow my lawn while DX6 is doing the hard work… Absolutely perfect…Thanks Maytronics…

Glad i exchanged my Polaris for the Dolphin DX6

ANDREW MITCHELL -

I had been using my Polaris for 2 years until the motor burnt out. The unit was sufficient , but the cost of a new motor was almost the cost of a new robot. I decided to review all the robots on the market and chose the Dolphin DX6 which i am delighted with. Not only does it out-perform the Polaris and leave my pool much cleaner, it also cleans the walls much better and does not get tangled. Furthermore the filter is easy to clean, definitely recommend this model.

Great Cleaner - Poor Instructions

Mike R. -

There were very brief instructions (pictures) about how the robot timer schedule is determined. Also several features of the operation are not explained. After several emails, I think we have it mostly figured out.

Disappointed

Melanie -

I bought this unit based on outstanding reviews. While it does clean admirably well when it works, I have had several problems. Within the first year, the rubber treads started to jump their track repeatedly. I sent the unit back for repair and while they did something to fix it, it still jumps the track, just far less often now. The remote control is nearly worthless- not at all intuitive to use and no useful functions. Did not come with any instructions. I run the robot daily and because it shuts itself off after a few days, I have to remember to check when it is off and restart the “auto” function. I have no idea who decided it needed to shut off after x number of days- but if you have to have that feature, then why not allow the user to determine the number of days? The filter bag is a cool idea with regards to re-using, but it is a pain to install/remove and very difficult to clean it well due to the thick seams. I ended up going back to using replaceable filters. The plastic housing is not very sturdy and the edges are wearing and chipping/ cracking where the unit bumps up against the wall. I love the long cable, but after a week mine is twisted up and I have to remove it and untangle/untwist it. It gets a 5 star for cleaning ability, but for the major $$ cost, the problems I have had take it to a 3 star and I will definitely shop around first when I need to replace this unit.
