Eufy RoboVac 11S (Slim) vs Roborock S8 Pro Ultra
Side-by-side comparison of features, pricing, ratings, and alternatives.
The Eufy RoboVac 11S (Slim) is a compact, low-profile robot vacuum designed for effortless daily cleaning. Its 2‑cm height lets it glide under furniture while the BoostIQ technology automatically increases suction power when needed. Equipped with BoostIQ, a 100‑minute runtime, and a triple‑filter system, the 11S delivers consistent performance on hard floors and low‑pile carpets, all while staying whisper‑quiet at 55 dB.
The Roborock S8 Pro Ultra combines robot vacuuming and mopping with a dock that automatically washes and hot-air dries the mop pad after each cleaning cycle, addressing the common complaint of dirty, smelly mop pads with other robot vacuum systems. A retractable mop lifts automatically when the robot detects carpet, preventing wet mopping cloths from soaking carpeted areas while vacuuming continues normally across all floor types. Reactive AI 2.0 obstacle avoidance combined with LiDAR navigation and multi-level mapping lets it clean multiple floors of a home intelligently, remembering furniture layout and no-go zones set through the companion app.
Around $1,599.99 MSRP, frequently discounted.

Works, with some caveats
Roborock S8 Pro Ultra is solid overall, though it's not perfect. On the plus side, genuinely reduces manual mop maintenance. That said, dock is large and needs dedicated space, which held us back from rating it higher.
