What's inside
When testing pool cleaners through a full season of heavy debris, pine needles, and stubborn algae, you quickly learn that a mediocre robot just creates more work. Standing by the edge of the water with a tangled cord or fishing out a unit that died halfway across the shallow end is endlessly frustrating, which is why choosing the right automated cleaner matters so much for your maintenance routine in 2026.
That exact frustration brings us to a head-to-head showdown between two of the most talked-about options on the market: the Dolphin Nautilus CC and the WYBOT C1. Having spent weeks putting both machines through their paces on various pool surfaces, dealing with fine silt and heavy leaf loads, I found that they approach automated pool care from entirely different engineering philosophies.
