Often when comparing robotic cleaners it can be difficult to determine which model will work best for you. Sometimes you think you’ve got it figured out only to discover another model which is similar but you’re not sure what the differences are. This article is dedicated to helping you determine the differences in what we’re calling Dolphin E20 vs Nautilus CC.
Dolphin E20 vs Nautilus CC Review




When we first started comparing robotic pool cleaners we thought we’d be able to help numerous people separate the wheat from the chaff. The Dolphin E20 vs Nautilus CC comparison is no different. There are many similarities and some differences, and in this article we’ll review the important features to consider.
Pool Size
First, keep in mind you need to make sure your pool can be cleaned by a robotic cleaner with a 50’ cord. For both the Dolphin E20 and Nautilus CC, Dolphin recommends pools no longer than 33 feet. Keep in mind this is dependent on your GFCI outlet location.
Always remember you must not use an extension cord at any time around a swimming pool for any reason. If you don’t have an outlet within close proximity of the pool, hire a licensed electrician to put one in. It is a National Electric Code requirement (NEC 680.22) to have an outlet no closer than 6 feet. Also, you can have it no further than 20 feet from a swimming pool.
Pool Shape
First, let’s start with the shape of the pool. The Dolphin E20 is designed to work well in any shape pool. Unlike the Dolphin Nautilus CC which Dolphin says will only work in a round or rectangular shape pool.
The Dolphin E20 and the Nautilus CC will climb the walls of your pool, but will not scrub the waterline like some other cleaners in the Dolphin cleaner family. When comparing Dolphin E20 vs Nautilus CC you’ll find both cleaners are floor and wall only.
Track Location
Both the Nautilus CC and the E20 have external tracks. That means the tracks are not partially internal and partially external. This can be a great feature as the cleaner ages. This is because more of the mechanical aspect of the cleaner is exposed and servicing the cleaner will be less complicated. This cleaner uses the older tried and true 4000 GPH circulation system, which Dolphin has included in their cleaners for years. They provide a 2 year warranty on the cleaner.

Pool Cleaner Weight
The gross weight (including the cord) of the Dolphin E20 and the Nautilus CC is right around 23.5 pounds. When compared to other more expensive models it’s relatively light. These cleaners are light enough for most people to muscle around safely. However, you ought to consider the caddy. Remember you don’t want to be in a situation where you drop the cleaner as this is how most cleaner damage occurs.
Model Access
The Dolphin E20 and Nautilus CC are top access models which 95% of the Dolphin cleaners have included standard at this point. This means you simply set the cleaner on the deck, and you can flip open the top and pull out the filter box for cleaning. Very simple and no balancing of the cleaner on its back while you clean it out.
Dolphin E20 vs Nautilus CC Summary
When considering the Dolphin E20 vs Nautilus CC, the major difference is the restriction on the shape of the pool. The Dolphin Nautilus CC is designed primarily for round and rectangular pools, while the Dolphin E20 is designed for all pool shapes. Beyond this, the only difference we found is the casing color scheme.
The Nautilus CC is white and Blue, while the color scheme of the Dolphin E20 is black and white. Both cleaners have a blue cord. If you have a round or rectangular pool, it comes down to personal preference which cleaner you prefer in your pool. If you have any other shape pool, the Dolphin E20 is the cleaner for you.
