Ultimate Dolphin Pool Robot Guide (2026): ALL 28+ Models Compared

If you're trying to decide which Dolphin robotic pool cleaner to buy in 2026, this is the most complete buying guide available. I tested nearly every Dolphin robot on the market and compare the entire lineup, including the ProLine, Max-Series, Explorer, Nautilus and even the commercial Wave series. In this guide, I explain the real differences between Dolphin's ProLine, Max-Series, Nautilus, Explorer, Active, S-Line, T-Line, Liberty cordless lineup, and the brand-new EON robots. I also cover which models offer true waterline cleaning, NanoFilters, weekly timers, Wi-Fi, app control, step and sun shelf cleaning, commercial-grade motors, and the best warranties. One of the biggest changes for 2026 is the warranty structure across the lineup. I explain why that matters, why the ProLine robots continue to offer exceptional value, and why several popular Nautilus models may not be the best buy compared to similarly priced alternatives. Whether you own an above-ground pool, vinyl liner pool, fiberglass pool, or gunite pool, I'll help you determine which Dolphin robot fits your pool size, budget, and cleaning needs.
