Spend more time in the water and less time maintaining it. The Dolphin Liberty 400 brings dependable, automated cleaning to your pool so you can skip the manual vacuuming and brushing. Here's a clear look at what this model does well, and what to weigh before you buy in 2026.
Clean like a pro. With wall coverage, the Dolphin Liberty 400 can clean and scale your walls with precision and power. While Wall Climbing is a great feature, don't get this confused with the superior waterline cleaning feature.
Dolphin Liberty 400 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 Liberty 400.
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.
To set expectations: the Liberty 400 uses standard filtration rather than NanoFilters and isn't a ProLine or Max-Series machine. If premium, fine-debris filtration and commercial-grade power are priorities for you, a ProLine cleaner like the Dolphin Premier or a Max-Series model is a worthwhile upgrade.
The Dolphin Liberty 400 includes everything you'll need. Here is what is included with the unit:
Dolphin Liberty 400 Unit
Power Supply
Standard Filters
2 Year Warranty
Simply plug and play. All robotic pool cleaners are ready to go right out of the box. No booster pump or assembly needed. The Liberty 400 has everything needed to get started in its box. It's that easy.
