Beijing Roborock Technology Co.,Ltd.
SB C&S Corp.
Beijing Roborock Technology Co.,Ltd. (Headquarters: Beijing, China; President: Quan Gang), a manufacturer and developer of robot vacuums and stick vacuums, and SB C&S Corp. (Headquarters: Minato-ku, Tokyo; Representative Director, President & CEO: Kazuya Kusakawa), which provides the world's latest IoT products and smart home appliances, will launch the next-generation flagship robot vacuum cleaner 'Roborock Saros 20 Sonic' (hereafter 'Saros 20 Sonic') on Monday, June 1, 2026, at Yamada Denki stores nationwide (excluding some stores) and Yamada Web.com. Ahead of the release, pre-orders will begin on Monday, May 18, at Yamada Denki stores nationwide and Yamada Web.com.
The 'Saros 20 Sonic' is equipped with a high-speed vibrating mop that scrubs floors at 4,000 times per minute with high downward pressure. The mop physically extends to thoroughly clean along walls and deep into corners of the room. Furthermore, it flexibly adapts to complex steps and carpet environments, implementing a lifting mechanism that smoothly climbs over double thresholds up to 8.8cm high. It also adopts LDS (Laser Distance Sensor) technology to achieve innovative levels of smooth driving and mopping, as well as highly accurate mapping even over wide areas.

■ From Wiping to Polishing: Evolved High-Speed Vibrating Mopping System
The high-speed vibrating mop system, featuring an independent motor, mops powerfully with sonic vibrations of 4,000 times per minute and 1.75 times the strong pressure compared to the previous 'Saros 10' model. It firmly wipes away stubborn dirt stuck to the floor, keeping it smooth. The mop head, boasting a 27% expanded vibration area, adopts a physically extending structure. When it detects a wall, the high-speed vibrating mop slides out, reaching 0mm to the wall for gentle mopping. Also, by using a highly absorbent mop, it wipes the floor evenly and beautifully. Furthermore, within the Roborock app, water volume and vibration intensity can be adjusted individually.
■ Max 8.8cm: Unstoppable Cleaning Beyond the Steps
When crossing threshold steps, an automatic lifting mechanism for the main body is activated. It can stably climb over double steps up to 8.8cm. Additionally, it supports carpets up to 3cm thick, automatically adjusting the body height to match the carpet's pile. For deep-pile carpet cleaning, it achieves a high dust removal rate of 30%.
■ 36,000Pa Strong Suction and Two Brushes Achieving 0% Hair Tangling to Minimize Maintenance
With a powerful suction force of 36,000Pa, it thoroughly cleans floors, from fine house dust buried deep in carpets and between flooring gaps to large debris like pet litter. Also, two spiral main brushes guide dirt and hair to the dustbin entrance for powerful suction. The asymmetrically designed arc-shaped side brush gathers dirt without tangling long hair or pet hair, utilizing flexible movement via centrifugal force. Both brushes achieve a 0% hair tangling rate, reducing maintenance effort.
■ Understanding Room Shapes for Efficient Cleaning
An ultra-thin design of 7.98cm allows it to enter low spaces under furniture. The top LDS laser sensor automatically retracts and rises, making it possible to clean low spaces such as under furniture. Even when the LiDAR sensor is retracted, it maintains a 100-degree rear viewing angle, achieving a 100% success rate in mapping and escaping even in spaces as tight as about 7cm. Navigation uses the 'Reactive AI 3.0 Obstacle Recognition Function,' which identifies over 300 types of objects using triple structured light, an RGB camera, and VertiBeam™ side structured light to smartly avoid cables and scattered items.
■ Minimizing Post-Cleaning Effort with the New 'New RockDock®'
The latest multi-functional charging dock, 'New RockDock®', breaks down oil stains through 100-degree high-temperature water washing, achieving 99.99% sterilization. Afterwards, it dries the mop, dock bottom, and entire dust path with 55-degree hot air, suppressing mold and odors. Furthermore, by lifting only the mop during suction mode, secondary pollution is prevented.
