Dreame X40 Ultra vs Roborock S8 Pro Ultra
Side-by-side comparison of features, pricing, ratings, and alternatives.
The Dreame X40 Ultra roams your home autonomously, using LiDAR navigation to map multiple floors and target high-traffic zones. Its built-in self-emptying dustbin holds up to 0.5 L of debris, so you can go weeks without manual emptying. When switched to mopping mode, retractable pads glide over hardwood, tile, and laminate, delivering a consistent damp clean. All functions are controlled via the Dreame app, allowing scheduling, no-go zones, and real-time status updates.
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.
