## What reviewers say

**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.)
