What reviewers say
Sourced tester consensus for each — the "what people who used it think" layer, not just specs.
Dolphin Nautilus CC Plus w/Wi-Fi
Only one whitelisted tester, Reviewed (USA Today), hands-on reviewed this exact Wi-Fi model — six weeks in a 35,000-gallon in-ground pool — and rated it their best robotic pool cleaner. Praised for powerful suction, easy wall-climbing, and easy-clean dual filter baskets; faulted for occasionally getting stuck on steps and an on/off-only power base. (1 sourced review, 1 lab-tested.)
Praised: Powerful suction with smart navigation removes debris quickly and efficiently; Climbs walls and takes corners easily, even on non-rectangular pools; Dual filter baskets are easy to access and clean (compared to a dryer lint trap).
Flagged: Occasionally gets stuck on pool steps if left unattended; Power base is on/off only — all other settings require the app.
