Roborock launches Saros 20 Sonic at CES 2026
Roborock unveils the Saros 20 Sonic at CES 2026, combining advanced sonic mopping, adaptive mobility, and intelligent navigation.
Roborock has unveiled the Saros 20 Sonic at CES 2026, expanding its Saros product line with a new robotic vacuum and mop designed to address more complex home cleaning conditions. The company positions the Saros 20 Sonic as a precision-focused device that combines advanced mopping, adaptive mobility, and intelligent navigation within a compact form factor. The launch reflects Roborock’s continued push towards fully autonomous, hands-free home cleaning systems.
At the centre of the Saros 20 Sonic is the VibraRise 5.0 Mopping System, which introduces an extendable sonic mop designed to improve edge and baseboard cleaning. The system delivers 4,000 vibrations per minute and applies increased downward pressure to break down dried stains more effectively. Unlike multi-pad designs that can leave gaps along edges, the single mop head physically extends to clean flush against walls, enabling edge-to-edge coverage with minimal streaking.
Users can customise the cleaning approach through the Roborock app, independently adjusting water flow and vibration intensity based on floor type. Lower water levels can be applied to sensitive surfaces such as hardwood, while higher intensity settings target grease and tougher kitchen messes. This level of control is intended to balance cleaning performance with floor care, particularly in mixed-surface homes.
Adaptive mobility and carpet performance
Beyond mopping, the Saros 20 Sonic is designed to navigate real-world household obstacles more effectively. The AdaptiLift Chassis 3.0 allows the robot to analyse and memorise the best way to cross thresholds using a combination of vision systems, adaptive algorithms, and a mechanical structure that includes a main wheel, auxiliary wheel, and climbing arm. This enables the device to handle double-layer thresholds with a combined height of up to 8.5 cm, a common challenge in multi-room or older homes.
The same system also supports a dynamic cleaning mode for carpets up to 3 cm thick. By adjusting chassis height in real time, the Saros 20 Sonic maintains consistent suction across different pile heights. Roborock states that this results in a 30 percent improvement in dust pickup on long-pile carpets compared with standard designs. When Deep Carpet Cleaning is enabled, the Main Brush Stabilisation Module keeps the brush in a stable downward position, increasing agitation and improving debris removal.
Suction performance is driven by a 35,000 Pa HyperForce digital motor, paired with a Dual Anti-Tangle System. This includes the DuoDivide main brush and FlexiArm Arc side brush, which extend to reach corners and edges. The system is engineered to manage hair strands up to 40 cm long, targeting homes with pets or long hair while reducing manual maintenance and interruptions during cleaning cycles.
Intelligent navigation, docking, and connected features
Navigation is handled by the RetractSense Navigation System, designed to support the robot’s ultra-slim 7.98 cm body. The primary LiDAR sensor automatically retracts when the robot moves under low furniture, while a rear-facing view allows it to continue mapping and navigating without losing orientation. Roborock reports a 100 percent success rate in spaces just above 7.98 cm in height, reducing the risk of the robot becoming stuck in low-clearance areas.
Obstacle avoidance is supported by Reactive AI 3.0 Obstacle Recognition, which combines triple structured light, an RGB camera, and lateral structured light to identify more than 200 types of objects. This enables the robot to avoid cables, clutter, and other common household obstacles, supporting uninterrupted cleaning runs in busy environments.
The Saros 20 Sonic is paired with a new RockDock system designed to handle maintenance tasks automatically. Mop washing uses 100°C hot water to dissolve grease and achieve a reported 99.99 percent bacteria removal rate. Drying is carried out using 55°C warm air, which circulates through the mop, dock base, dust bag, and internal dust pathways to reduce moisture, odours, and mould. Additional features include smart dirt detection for re-washing heavily soiled areas, automatic detergent dispensing, dust emptying for up to 65 days, and fast charging that replenishes the 6,400 mAh battery in 150 minutes.
On the software side, the device runs on Roborock SmartPlan 3.0, which identifies room types, learns user habits, and adjusts cleaning strategies automatically. Pet-friendly features allow the robot to recognise and avoid pets, capture images, and support real-time video check-ins. Voice control is available through the built-in “Hello Rocky” assistant, which operates offline and supports Matter integration for compatibility with Amazon Alexa, Apple Siri, and Google Home.
Roborock has confirmed that the Saros 20 Sonic will begin its international rollout in 2026, with pricing and market availability to be announced closer to launch.
