What features does it have?
The Dolphin S50 is an entry-level robotic cleaner aimed at smaller in-ground pools, and heading into 2026 it's still one of the most budget-friendly ways to stop vacuuming by hand. It's genuinely plug-and-play and gets the basics done — but before you buy, it helps to know exactly what this model does and doesn't include.
What is Dolphin S50 missing?
Waterline Cleaning
Dolphin S50 does not included waterline cleaning. Not only is this an essential feature that you'll want when looking for a pool robot, but one you will likely need. Waterline cleaning enables the robot to climb and reach the dirtest part of your swimming pool. Without this feature, you'll still need to manually clean your waterline by hand with a brush to prevent any algae or scum that builds up. It is one feature that you'll need that is not included with the Dolphin S50.
Leaf Bag
With leaves being a common issue, it would be safe to assume most pool robots utilize a leaf bag. Well, no so fast. Nearly every robotic pool cleaner is missing a leaf bag, except the Dolphin Premier. If you have a lot of leaves, this is the best pool robot for leaves. Not to mention the Premier's 3 year warranty, Dual Commercial Motors, and Multi-Media™ make it one of the best models available.
Keep in mind the S50 ships with standard filters and a single-motor build. It does not include NanoFilters for ultra-fine debris capture or ProLine commercial-grade motors. If you want maximum suction and the cleanest water possible, step up to a ProLine cleaner such as the Dolphin Premier, or explore the Max-Series. Not sure which fits? Compare them all in our best robotic pool cleaners guide.

How to set up the Dolphin S50
