do you leave the unit in the pool between cleanings or take it out each time when it is finished cleaning?
James B on Jun 8, 2017
BEST ANSWER: Yes. I only take it out to clean the filters.
is it safe for vinyl liner pools ?
robert p on Jun 3, 2017
BEST ANSWER: I have always used this type of robotic cleaner with my above ground pool that has a vinyl liner, and it has not caused any problems.
Can you use this to clean the pool when you first open it for the season? Some small debris like leafs and algae are blown in under the cover through the winter
Stephen C on May 24, 2018
BEST ANSWER: This really depends on the type of cover and debris. If it is covered with heavy silt and/or leaves you will have to pull it out and empty the filter chamber often. Also, because it is random in its coverage, it will take pretty long to get the entire bottom. I generally vacuum to waste (bypass filter system) through my pump, it is quicker and more effective for heavy sediment and leaves. That being said, this is a nice product and cleaning the filter is much easier than my last unit. It does hang up on my stairs occasionally but i can live with that for the convenience it offers.
does this include power supply and caddy?
A shopper on May 8, 2017
BEST ANSWER: This does include the power supply but the caddy is sold separately. The caddy is sold on the website and definitely worth the $110. Makes storing much easier.
After glancing thru this Q&A info..I notice the ironic/coincidence all reply from men AND nearly reply from others daily, it is all positive " feedback, ref this product, But i obviously am skeptical & prefer NOT to waste $$$$ ... is this the correct information & trustworthy?
A shopper on Jun 30, 2017
BEST ANSWER: I'm a woman and I love this unit. It does a really great job, and I've been so glad I bought this. It's enabled me to have so much more time IN the pool instead of spending time cleaning the pool.
What is the purpose of the “SELECT” button on the power supply?
Doug J on Jul 1, 2021
Can this unit remove leaf debris from the floor of a pool (small bits of leaves, not whole leaves)?
A shopper on Feb 24, 2018
BEST ANSWER: Yes, this pool cleaner can definitely remove leaves - whole leaves as well as bits of leaves. When leaves started falling before we got our pool cover on, there were times when we needed to run it for two cycles to get all the leaves (and empty it of all the leaves in between the cycles), but it got them all. This is one of the best purchases I've ever made. I put it off for a long time worrying that the expense wouldn't be worth it, but this thing does a great job. Every time I throw it in the pool I'm so thankful for all the time I now get to spend swimming instead of cleaning the pool.
I have a caddy from an older Maytronics model. Will it work for this one?
A shopper on Jun 14, 2020
BEST ANSWER: I wouldn’t be able to tell because this was the only sweeper I’ve had.
When taking cleaner out of the pool, does any of the collected debris go back in the pool? I have that issue with my Smart Pool cleaners.
A shopper on Jul 24, 2018
BEST ANSWER: Yes some will but I try to bring it to the surface - then hold the handle and take it out on one full swoop rather than trying to let it drain over pool. Thereby lessening the amount that falls back into the water. So a little does - but usually no large debris just some pollen or similar water.
Do I need a special cord /attachment to hook up? Or just ext cord from house to plug robot in? 1st timer, been looking long enough to be confused as to which one TRULY IS THE BEST.. I'm still not sure..I have a VERY odd in ground shaped pool w/ledge & deep end, will this " help" or GET JOB DONE CORRECTLY?
A shopper on Jun 30, 2017
BEST ANSWER: Overall I like this robot. I also have an in ground pool with stairs and a ledge and I don't really think it climbs the stairs too well. I don't sit and babysit it while it is on but I've never caught it on the individual steps. It cleans the pool very well and doesn't miss anything on the normal pool surface. It comes with all the equipment you need to get going. It has a transformer box that plugs into the wall and then has a low voltage waterproof line running to the robot.
Can you swim in the pool while this is in the pool and working. Seems like it could be a shock hazard?
A shopper on Jul 29, 2017
BEST ANSWER: Technically you can - but I don't know why you would and I think you shouldn't since there is the cord moving around the pool and any of the dirt that you are looking to vacuum up will be pushed around and not picked up as easily. Of course many will also say - why get in the pool when an electric device is operating....? It works great !
Do I just plug it in an outlet or hook it up to the filter?
A shopper on Jul 23, 2017
BEST ANSWER: Just a power outlet. It has two filters that are removed (very easily) and cleaned. I have had this about a month. Great product I wish I purchased sooner. Hopefully it will continue to clean my pool for many summers to come. Best of luck.
Can I use an extension cord with this ?
Mark W on Jun 27, 2017
BEST ANSWER: According to Maytronics an extension cord should never be used.
does it clean the waterline?
A shopper on May 7, 2022
BEST ANSWER: I have owned 2 of these, one for a vinyl pool and the other gunnite. Highly recommend this cleaner. It hugs the walls amazingly well so it does a good job on the walls as well as the floor. As for the waterline, it does a pretty good job but you'll still have to occasionally hand scrub the waterline.
How long is the power cable ??
Kenneth L on Jul 25, 2021
BEST ANSWER: The power cable to the control module is about 4 feet. The cable connecting the module to the robotic pool cleaner is 25 feet.
Will the cleaner clean steps?
A shopper on May 20, 2020
BEST ANSWER: My steps are a bit narrow (maybe 24") and the unit does an OK job with them. I usually give the steps a quick brush before using the unit.
How do you install filters into basket....inside or outside??
A shopper on Oct 20, 2018
BEST ANSWER: inside, very easy to clean, this is the best pool cleaner I have ever bought! and I have had pools for 40 yrs.............. i have not touched my pool for 2 years! just chems. and this thing :)_
A shopper on Aug 24, 2018
BEST ANSWER: No it does not.
I have a 30/40 in grown pool will this do the job ?
Plastered 4414 on Jun 29, 2018
BEST ANSWER: I have 20x 40 in ground and it does well. We do have to do some minimal brushing afterwards. I've had the cleaner over a year with no problems. There has never been a need to use the old pool vac from the intake line since we've had it.
Does it get stuck behind pool ladders?
Bob B on Jun 9, 2018
BEST ANSWER: I’ve had one for a year and it did only once or twice. It will back itself up when it can’t move forward. Hasn’t happened in a long time. In my case it may have been because of an old ladder. Hasn’t happened since I replaced ladder.
I recently bought the Nautilus Plus cleaner, It is terrific. When I purchased it I thought that a “caddy” came with it, I did not receive one. Is this a separate item?
tom C on Jun 8, 2018
BEST ANSWER: mine came with a caddy. You have to assemble it. I suggest you call customer service and discuss it
does it works with 220v?
Marian on Nov 17, 2017
BEST ANSWER: My house has 110V. But the Dolphin Nautilus power supply input shown the range of 100-250VAC 50/60HZ 2A. I think it will work with 220V AC. You may call Maytronics to make sure.
my pool is 20x40 can i use this cleaner?
A shopper on Jun 18, 2017
BEST ANSWER: yes, I have had pools for 30 years, this is by far the best thing I have ever purchased!! works exactly as it states!! ....
What filter media, if any, comes with it?
Paul C on Aug 31, 2021
BEST ANSWER: The Dolphin channels the water and debris it vacuums through two sizable top-loaded cartridges enveloped by a tightly woven synthetic mesh that traps dirt, slime, leaves, etc. It does not require DE, some other compound, or even a replaceable filter, If that is what you meant by filter media. This is the best robotic cleaner I have ever purchased. My 40X20 pool is ancient and its intake does not provide enough suction to operate a hand-held vacuum. I rely entirely on the Dolphin to vacuum and scrub the pool from season open to close and, in three years, it has never let me down. The suction is very powerful and it does a phenomenal job of climbing and aggressively cleaning vertical surface, in addition to the liner bottom. The filter cartridges are easy to remove, open and hose clean (5 minutes tops), something I do after every 4 or so cycles. The Dolphin even survived being accidentally left outdoors for the duration of a cold NY winter.
bob a on Jun 9, 2021
BEST ANSWER: Yes, check Amizon too for pricing, and Pool supply. There is also a great video on YouTube for instructions. I had my Nautilus for just under 4 years, I live in New England so seasons are short. I would clean my pool maybe twice a week, then it stopped working. Looked to all pool supply places, NO ONE repairs Nautilus! You have to send it back to the company, pay for shipping ect. I did find a place locally. Well, they told me motor was no good!! So not pleased with Maytronics at all. Next season I’ll look for another brand that I can have it repaired if needed. Just thought I’d let you know of my experience. Good luck!!!
the power suply this dolphin nautilus CC work AC220 volts?
Luis Ferreira on Apr 24, 2020
BEST ANSWER: 110 regular plug-in will do the trick, no special wiring required
Will it work on above ground pools ?
A shopper on Jun 9, 2019
BEST ANSWER: No reason it can’t it’s a self contained unit that just needs to be plunged in to a 110 outlet. All the filtering and suction is contained within the unit.
My pool is 14' x28' plaster coated and has a salt system. Is this DOLPHIN Nautilus Plus the most appropriate cleaner for it? Is there a better model?
Amethyst on Aug 20, 2017
BEST ANSWER: I do have a salt system I don't think that makes any difference to the cleaner. We will leave the cleaner in the pool and set the controller to run every other day, only remove it when we swim. There is no ill effects that I can see. The body is plastic, so no metal parts exposed to corrode. I'm very happy with mine.
Can I leave in under pool cover when not using pool?
LeRoy C on Sep 7, 2021
BEST ANSWER: Not recommended to leave in pool when not in use

Works great
The Dolphin far surpassed my expectations. When you clean it out each time, it takes approximately 15 minutes to retrieve it from the pool, remove filter cartridge, clean and rinse, put cartridge back in, and either put away or put back in the pool. If your pool has a lost of sediment and trash, you may have to repeat this cycle 2-3 times.

A fantastic cleaner
This cleaner has exceeded my expectations. Does a thorough job and reliably climbs on the walls. It is very powerful compared to our old external-pump bases unit.

In addition to vacuuming it does a good job filtering the water. We were without the pool pump for a few days waiting for a motor replacement. We used the Dolphin to filter and circulate the water in the meantime and water stayed clear.

Very happy with the purchase.

Works as advertised
This is our second automatic pool cleaner. This one is much better at handling our oval in ground pool. Covers the entire pool, including sides in about 2 to 2.5 hours. Cleanup is easy and quick. The micro-screens filters are much better than our previous one with a net type filter.

We were set on hiring a pool service prior to ordering this unit. We ran the unit and were so amazed with the results realized we didn't need a pool service at all.

Doesn't really scrub
The unit works well picking up loose dirt and debris from the bottom of the pool but it doesn't actually scrub. The belt that runs under the unit turns at the same speed it travels so it's not scrubbing, it just runs over it. The advertisement says it scrubs algea from the pool put it doesn't. I have been running it for 2 weeks now and the light algea I had is still there only now I have little one inch tracks from the units wheels. I would give it 5 stars if it actually scrubbed.

Nautilus after 2 weeks
Works well, easy to use and clean. Although it has not yet cleaned the old alge as well as I would have liked. I t seams to get slightly better afte each use, so, in time, maybe it will get the complete job done.

Very good but not perfect.
I've always used suction side cleaners like Kreepy Krauly for my inground, vinyl liner pool but they no longer last long enough to be worth the price. They pretty much require you to leave them running all the time too in order to clean the whole pool. I purchased the Nautilus Plus last year and have been very happy with it. It is very fast at cleaning my 20x40 pool and has only gotten stuck once or twice. It does not always clean the stairs which is my biggest complaint and one time one of the drive belts somehow came off and got jammed up in the unit so that I had to take it apart and re-install the belt.

Not sold completely
The machine does a nice job of cleaning debri from the bottom of pool. It is lacking in wall cleaning. The promotion video has it going up the walls. In reality, it doesn’t. Another fact not disclose in video or promotional pages is that pool vacuum needs to be taken out of the water when persons are in the pool.
For me as a 79 year old, it’s a pain to take out each time and store.
