Industry-Leading Obstacle-Crossing Power: AdaptiLift™ Chassis 3.0 dynamically raises the body to glide over thresholds and uneven floors without losing suction. Effortlessly crosses up to 3.46 in double-layer steps and cleans carpets up to 1.18 in deep, so every room stays fully cleaned, uninterrupted. (Based on internal testing by the manufacturer, under test conditions where the first threshold height does not exceed 1.77", the gap depth between the two thresholds is greater than 4.72" and does not exceed 5.51", and the second threshold height does not exkceed 1.69", the robot is capable of crossing double-layer thresholds with a combined height of up to 3.46". Actual performance may vary depending on environmental conditions and actual user usage.) Ultra-Precise Navigation with Fewer Missed Spots: Powered by StarSight™ Autonomous System 2.0, the advanced 3D ToF sensors build accurate maps in real time. The RGB camera enables the robot to detect and recognize over 300 obstacles to avoid clutter, reduce interruptions, and deliver smoother routes with more complete coverage. Cleans Under 3.13" Furniture with Ease: With its ultra-slim design, Saros 20 glides under sofas and beds as low as 3.13", removing hidden dust and pet hair from places you rarely clean. No moving furniture, no missed spots—just a deeper, more effortless clean every day. (The body height of the robot vacuum is 3.14". Due to slight vertical flexibility in the front structural components, the robot may achieve limited passive compression when entering low-clearance spaces, allowing access down to 3.13". However, please note that scraping may occur. Actual performance may vary depernding on environmental conditions) Extreme 36,000 Pa*, Zero Hair Hassle: The 36,000 Pa digital motor pulls dust, pet hair, and debris from deep floor gaps with ease. A dual anti-tangle system automatically handles hair buildup, cutting down manual brush cleaning—perfect for pet owners who want powerful, worry-free results. (Based on internal testing of the digital motor under specific conditions. Actual results may vary depending on products configuration and usage conditions.) Fully automated Dock for True Hands-Free Care: Brand New RockDock® features a new one-piece cleaning tray that boosts mop coverage and water capacity for deeper washing and quieter operation. Combined with 212°F* hot water washing, 131°F* hot air drying, self-cleaning maintenance, and up to 65 days of auto dust emptying, it delivers a truly hands-free experience. (*Based on internal testing by the manufacturer. The water at the clean water dispensers of the base can be heated up to 212℉ under standard atmospheric pressure (1 atm, 101.3 kPa) and the air at the base's outlet during drying can be heated up to 131℉ under room temperature. Actual temperatures mayvary depending on environmental conditions such as altitude and atmospheric pressure.) Edge-to-Edge Cleaning with Smart Reach: FlexiArm™ technology extends the side brush and mop to reach corners, edges, and under furniture where dirt hides. Mark curtains in the app, and the robot cleans behind them intelligently—leaving no blind spots and no missed messes. AI-Powered App Control: Control everything in the Roborock App, including SmartPlan™ 3.0, which learns your home and routines to optimize cleaning with one tap. Voice control, smart mapping, and the built-in RGB camera let you check in on your pets anytime, delivering a smarter, more effortless clean for pet-loving homes. (Supports 2.4GHz and 5GHz Wi-Fi)
