Roborock Launches 'Saros 20 Sonic', an Innovative Flagship Robot Vacuum with Retractable Sonic Mop and Advanced AI Navigation

Beijing Roborock Technology Co., Ltd., a manufacturer and developer of robot and stick vacuums, and SB C&S Corp., which offers the latest global IoT products and smart home appliances, will launch the next-generation flagship robot vacuum, the 'Roborock Saros 20 Sonic', on Monday, June 1, 2026, at Yamada Denki stores nationwide (excluding some locations) and Yamada Web Com. Pre-orders will begin on Monday, May 18, at all Yamada Denki stores and Yamada Web Com. The 'Saros 20 Sonic' is equipped with a high-speed vibrating mop that scrubs floors with 4,000 vibrations per minute*1 and high pressure. The mop physically extends to clean thoroughly along walls and into corners. Furthermore, it flexibly adapts to complex steps and carpeted environments, implementing a lifting mechanism that smoothly overcomes double sills up to approximately 8.8cm. It also adopts LDS (Laser Distance Sensor) technology for an innovative level of smooth travel and mopping, as well as high-precision mapping even in large areas. [Product Intro Video] https://youtu.be/btuCvwgBQ6Y ■ From Wiping to Polishing: The Evolved High-Speed Vibrating Mopping System The high-speed vibrating mop system, with its independent motor, powerfully mops with 4,000 sonic vibrations per minute*1 and 1.75 times*2 stronger pressure compared to the previous Saros 10 model. It effectively wipes away stubborn stains caked on the floor, keeping it sparkling clean. The mop head, boasting a 27%*3 larger vibration area, uses a structure that physically extends. When it detects a wall, the high-speed vibrating mop slides to reach 0mm*1 to the edge*4 for gentle mopping. The highly absorbent mop ensures an even, streak-free clean. Within the Roborock app, water volume and vibration strength can be individually adjusted. ■ Up to 8.8cm: Cleaning Doesn't Stop at Obstacles A lifting mechanism automatically raises the main body when crossing sills, allowing it to stably clear double sills up to 8.8cm high*5. It also supports carpets up to 3cm*1 thick, automatically adjusting its height to the carpet pile. For long-pile carpets, it achieves a high dust removal rate of 30%*6. ■ 36,000Pa Powerful Suction and Two Brushes for 0% Hair Tangle, Minimizing Maintenance The powerful 36,000Pa*8 suction thoroughly cleans everything from fine house dust in carpet depths and flooring gaps to larger debris like pet litter. Two spiral main brushes guide dirt and hair to the dustbin entrance for powerful pickup. An asymmetrically designed arc-shaped side brush uses centrifugal force for supple movements to gather long hair and pet fur without tangling. Both brushes achieve a 0% hair tangle rate*7, reducing maintenance. ■ Navigates Room Shapes for Efficient Cleaning An ultra-slim 7.98cm body allows entry into low spaces under furniture. The top LDS laser sensor automatically retracts and raises, enabling cleaning in low areas. Even with the LiDAR sensor retracted, it maintains a 100-degree rear field of view, achieving a 100%*9 success rate for mapping and escaping in spaces as small as 7cm. Navigation uses 'Reactive AI 3.0 Obstacle Recognition', employing triple structured light, an RGB camera, and 'VertiBeam™ side structured light' to identify over 300*10 types of objects and smartly avoid cables and clutter. ■ New 'New RockDock®' Drastically Reduces Post-Cleaning Chores The latest multi-functional charging dock, 'New RockDock®', dissolves grease with 100-degree*11 hot water washing, achieving 99.99%*12 sterilization. It then dries the mop, dock base, and entire dust path with 55-degree*13 warm air to prevent mold and odor. It also features a smart dirt detection function that uses an independent mop washing feature to detect dirt and re-wash/re-clean when only the mop is left in the dock during suction mode. It supports automatic detergent dispensing, auto-emptying for up to 65 days, and 150-minute fast charging*1, maximizing convenience when combined with the standard charging dock or optional water supply/drainage systems. ■ Advancing the Smart Home with Connected Intelligence The Roborock app learns room types and user habits to automatically optimize cleaning routines. It provides detailed, life-accommodating cleaning by increasing suction as needed, re-washing the mop based on its dirtiness, or automatically adjusting power to reduce noise during 'quiet time'. It also supports detailed carpet settings, allowing for focused rug cleaning or complete avoidance to prevent wetting. Mop lifting behavior and edge cleaning routes can also be finely configured for each room. Matter compatibility ensures smooth integration with Alexa, Siri, and Google Home for whole-home automation.
