The Dolphin Cayman sits right in the middle of Dolphin's lineup, and for me, it's the best value for small-to-medium inground pools (and even for above-ground pools). It builds on what I love about the Escape but adds features that make pool ownership way easier .Read T

Both had a spot on my video for the best robotic pool cleaner of the year, and you should consider both. But which is a better robot? After testing both with a monometer, I'm going to dig in and help you figure out if either of these robots is right for you. Let me say this right up front. I like both of these robots.

If you’re budget-minded, go Cayman. If you want more power, a bigger debris basket, true waterline scrubbing, and an anti-tangle swivel, the Quantum is worth the upgrade.Watch T
In practice, the brush does a decent job on the usual greenish algae films and on mineral deposits that tend to build up near the skimmer. If you've ever tried a traditional suction cleaner and watched it slip over the tiled edge without ever really making contact, you'll notice that the Cayman's brush actually presses against the surface thanks to its low center gravity design.Watch P
Overall, the Dolphin Cayman is super impressive. It works with any in-ground, above ground pool, including vinyl, gunite, fiberglass, and more. With it's strong brush, tracks, and SmartNav technology, it covers the pool floors and walls with ease and vacuums all debris, leaves, algae, and more into its filter basket.Watch A
