Dolphin Nautilus EON 120D

Name: Dolphin Nautilus EON 120D
Brand: Dolphin
Price: 1199 USD
Availability: InStock

Maytronics' EON 120D adds two things to the EON 100: real waterline scrubbing and a backwash filter, which rinses itself rather than needing to be hosed out by hand. The direct-store Nautilus version ships with a universal caddy but only a one-year warranty.

The two lists above come from the maker’s own specifications and this site’s arithmetic on them, not from owner reports. Where owner discussion has been read it appears in its own section below, so the two are never mistaken for each other.
