How we picked
This guide covers the 5 Dolphin listings of the catalogue pool: every robotic listing whose stated brand is Dolphin, for every pool type and power source the titles name. Each robot is compared on the details stated in its listing title: pool type, cordless and wall climbing, and on the live price printed on the page. The ordering rule places titles that state a pool type first, then titles by the number of other stated details (cordless and wall climbing, most first), then the order of the pool file. Of the 5 listings, 1 title names an inground pool and 2 titles state a wall claim; no Dolphin title states a cordless word, so the rest read "not stated by the seller".
How to choose
Dolphin as the stated brand
Every listing in this guide has a title that states Dolphin as its brand. The picks are compared with each other on stated details only; this guide never compares Dolphin with another maker.
Inground, above ground or both in the title
One Dolphin title here names a pool type: the Nautilus CC Pro Wi-Fi names an inground pool. The other four titles state no pool type, and this guide reads that as "not stated by the seller". It never guesses a pool shape, size or depth.
Wall climbing as the seller's claim
Two Dolphin titles state a wall claim: the Nautilus CC Pro Wi-Fi and the Proteus DX4 Plus. The guide quotes the title wording and never says how well or how high a robot climbs walls.
Cordless as a title word, and what not stated means
No Dolphin listing in this pool has a title with the word cordless, wireless or battery powered. Every pick reads "not stated by the seller"; no pick is called corded, because the catalogue holds no cable detail.
Run time, filter and app: read them on the listing
The catalogue holds no run time, charge time, filter fineness, app or remote data. The Wave 140 title names a remote and a caddy, but this guide treats those as title words, not details; read them on the listing and the maker's page.
Power, water and the maker's manual
For questions about electrical power near water, the maker's manual and a licensed electrician are where to read about it. Water quality topics are not covered by this guide; the WHO page in SOURCE PAGES is the reference for pool water guidelines.
Questions
Which Dolphin pick names a pool type?
Only the Dolphin Nautilus CC Pro Wi-Fi title names a pool type: the title says In-ground. The other four Dolphin titles in this pool state no pool type. This guide reads that as "not stated by the seller" and never guesses whether a robot suits a pool shape, size or depth.
Does this guide cover run time, filters, safety or warranty?
No. The catalogue used for this guide holds no run time, charge time, filter fineness, safety listing or warranty term. For run time and filter details, read the listing and the maker's page. For electrical power near water, the maker's manual and a licensed electrician are the sources, and the UL Solutions page is listed in SOURCE PAGES. Warranty terms are a question for the maker.
Why does no Dolphin pick here say cordless?
None of the five Dolphin listing titles in this pool contains the word cordless, wireless or battery powered. This guide reads that as "not stated by the seller", never as "corded", because the catalogue holds no cable detail.
How are the Dolphin picks ordered?
Titles that state a pool type come first, then titles with more stated details (a wall claim counts as one detail), then the order of the pool file. Live prices and stated details are compared side by side; the ordering never uses price.
Which Dolphin titles state a wall claim?
The Nautilus CC Pro Wi-Fi and the Proteus DX4 Plus titles both state a wall claim. The other three Dolphin titles do not. The guide quotes the title wording and does not say how well a robot climbs walls.
Does this guide advise on water chemistry or water quality?
No. This guide gives no advice on chlorine, salt, pH or other water chemistry topics, and the catalogue holds no data for them. For water quality in pools, the WHO guidelines for safe recreational water environments are listed in SOURCE PAGES.
