Dolphin Nautilus Plus Robotic Pool Cleaner with Clever Clean

The Dolphin Nautilus Plus Robotic Pool Cleaner is recommended for in-ground swimming pools up to 50 feet in length and will clean your pool walls, floor and cove. It is lightweight, easy to use and comes standard with two sets of top-access, easy-to-clean cartridge filters that includes a fine filter and a spring clean up filter. The standard cartridge filters are capable of picking up small, fine debris and the spring clean up filters are designed to only pick up larger debris.

The Nautilus Plus is extremely easy to use with simple plug-n-play technology. Just plug it in, push the start button and watch it go! There aren't any connections to your pool system or pre-installation needed.

The Nautilus Plus features IntelliScan full pool scanning technology cleans the floor, walls and waterline to ensure a sparkling clean pool. The system is similar to GPS in your vehicle, telling you the most efficient route to take from your location to your destination. The Nautilus Plus will scan you pool and learn its dimensions, shape, and size in order to most effectively and efficiently maximize the area of coverage. The Swivel Cable eliminates tangles and ensures that it stays free and clear, allowing for complete pool covers.

    GREAT Investment

    Posted by Richard on Jul 23 2019

    Love my Nautilus Plus, I've had this for about 4weeks now and its AMAZING! Wish I had done this year ago, would have saved myself time and more time. I've no algae at all this summer long and it's been a crazy HOT summer in the Northeast. This machine is a beast climbs walls like nothing and vaccums the pool with ease. This thing pics up rocks, sand, and bugs with no problem. I'll be interested in September to see how it fends against leaves. Based on what I'm getting right now, I think it will be no problem. Great purchase total worth the wait, we saved up two season to get it and I can't be any happier!

    Worth every penny.

    My pool has 2 filters now, my main filter and this robot. It truly filters my pool everytime it runs. As proof, my filter pressure has yet to increase since I started using the robot, my 35 year old pool light shines, my walls, previously covered by algae (4 times this summer), are gleaming white, and I only need a 3rd of the chemicals to accomplish this task. Don't buy a pressure-side cleaner. Why would you want to run your energy-hogging pump any longer then it has to? It will save you time and money. I no longer have to vacuum or brush my walls, at all, anymore. Just plug it in, put it in the pool, push the button, and walk away. Or sit there and watch it climb your walls, steps, and waterline. It's entertaining. Clean-up takes 5 min. Pull out filters, hose off, and place back into the machine.

    So far so good

    Third Maytronics robotic pool vacuum I've had. Works great now, but the last 2 broke right after 2 year warranty expired. Both of those worked great at first, then stopped climbing walls & covering the pool like they did at the beginning and then eventually stopped. First one it was the motor, second one the gear box. So let's see how this one holds up. Still the best robotic pool vacuum - especially for the money. Just wish they lasted longer. Our pool is only open 6 months a year, so not being used year round. Do like the top filter system, much easier & faster to clean; otherwise basically the same unit as the first two.

    So far a very good product

    Posted by Bill on Jun 13 2017

    After reviewing as much as possible about Robotic Pool Cleaners I picked the Nautilus. This was based on reviews as well as costs. So far it has worked as advertised. It seems to be getting "smarter" the more I use it. At first It seemed that it would not run the full cycle, but that was an error on my part. I needed to clean out the filters which were doing such a great job that they filled up fast. This was because I was using the system for the first time to open my pool. Since then the system runs about four or more cleaning cycles before needing to be cleaned out.

    At this point I would recommend this as a great mid-line product that is very effective for cleaning with out all the bells and whistles that more expensive products have, but to me these are just more things that can go wrong and do not add any real efficiency or better cleaning results.
