Why Dolphin Nautilus Pool Up?
Stronger Motors & Wall Climbing
With larger motors pushing over 4500 gallons per hour, the Dolphin Nautilus Pool Up doesn't just clean the pool floor like other cleaners, but goes all the way up the wall with advanced wall climbing.
Massive Filter Bag
The Nautilus Pool Up gets away from the Gen-1 filter cartridges and goes a new direction: the filter bag. With a higher micron rating, the filter bag captures leaves, twigs, dirt, and even algae as it outperforms other models.
Evolution Series™
For the first time in a Dolphin, the Nautilus Pool Up can be easily upgraded, as part of the Evolution Series™. Add UltraFilters or add a weekly timer to automate your pool cleaning.
No Restocking Fee & 30 Day Trial
Try the Dolphin Nautilus Pool Up for 30 days with no restocking fees. With a 1 year warranty included, feel confident in trying any Dolphin pool cleaner from us.

The newest Nautilus, with commercial-grade motors and a filter bag. Here is what Pool Up owners say.
“I have 2 huge oak trees near the pool and they are litter bugs. My pool is around 18,000 gallons, in ground, and it has no problem keeping the pool spotless! Easy to empty and clean.”M. D. B.Verified buyer
“The robot cleaner does an amazing job. It has an easy to use activation panel and sturdy cord for retrieval. Very pleased.”Kim S.Verified buyer
“Needed a good cleaner for our gunite pool. Had no idea how easily gunite stains. Pool cleaners that work well on liner pools do not perform the same on gunite.”BenGunite pool
“We were avid Polaris users and when our Polaris finally quit working we decided to go with the Dolphin. We are thrilled with the performance! It's easy to clean and works extremely well in our salt water gunite pool.”Kim S.Salt water gunite pool
“Great quality product.”Bert C.Verified buyer

Questions about the Nautilus Pool Up
What is the Evolution Series™?
The Pool Up is the first Dolphin Nautilus that can be upgraded after you buy it: add the UltraFilter kit for fine debris and swap it with the bag, or add a weekly timer power supply to automate cleanings.
Does it climb walls?
Yes. Commercial-grade motors pushing over 4,500 gallons per hour take it all the way up the wall, with a front and a back brush scrubbing as it goes.
What does the filter bag catch?
Leaves, twigs, acorns, dirt and even algae. Its high capacity means fewer stops to empty it, and the optional UltraFilters take over when the water needs polishing.
Will it work in my pool?
In-ground and above-ground pools. Not sure? Ask a Dolphin specialist before you buy.
What does the 1-year warranty cover?
Maytronics warrants the robot against defects in materials and workmanship for 1 year. It is not prorated and not limited by the number of cycles. Service is available through 1,200+ Dolphin dealers. Read the full warranty.
What if it isn't right for my pool?
Try it in your own pool for 30 days. If it isn't right, return it with no restocking fee; you pay to ship the original product back. If you exchange it for another model, we'll ship the replacement free. See the return policy.
