Dolphin is one of the safest robotic pool cleaner brands to start with, but every Dolphin is not the right buy. Some are floor-only. Some clean waterline. Some have Wi-Fi. Some are corded. Some are cordless. The best Dolphin depends on your pool size and debris problem.

The short version
Start with the problem your pool actually has. Leaves, fine dust, wall grime, waterline scum, floating debris, and above-ground floor dirt are not the same job. The best robot is the one that handles your must-have cleaning area without forcing you to pay for features you do not need.
Dolphin Premier
The Dolphin Premier is the safest overall pick when leaves, mixed debris, and waterline cleaning all matter. It is a corded Dolphin built more around cleaning flexibility than app features.

How to choose a Dolphin
Start with pool size, then decide whether you need waterline cleaning, app control, cordless operation, leaf handling, or above-ground simplicity.
Dolphin corded vs cordless
Corded Dolphins are usually better for scheduling and long-term simplicity. Cordless Liberty models are better if you hate cables.
Waterline matters
Nautilus CC Plus Wi-Fi is popular, but it is not the waterline pick. Compare Premier, Quantum, Explorer E70, Sigma, Supreme, Liberty 600, or Liberty 400 if waterline is important.
Common mistakes
Mistake 1: Buying Wi-Fi when you do not need it
A no-app cleaning-first Dolphin may be better for your pool.
Mistake 2: Ignoring waterline cleaning
Wall climbing and waterline scrubbing are not the same.
Mistake 3: Buying too small
Do not buy a 30–33 ft model for a 50 ft pool.
Mistake 4: Forgetting leaves
Heavy leaves need basket/filter flexibility.
Final verdict
Dolphin Premier is the best overall Dolphin for serious in-ground pools, especially with leaves. Explorer E70 is the premium app-connected pick. Liberty 600 and Liberty 400 are the cordless choices. Nautilus CC Plus Wi-Fi is the popular midrange choice if waterline cleaning is not required. E10 is the above-ground pick.
