FAQ

  • What are the key cleaning-performance upgrades of the Saros 20 Sonic compared with the Saros 10?

    The Saros 20 Sonic introduces several major improvements in cleaning performance. Suction power has been increased to 36,000 Pa, significantly enhancing dust and debris removal from carpets and deep crevices. The mopping system has been upgraded to VibraRise® 5.0, featuring an extendable mop that applies 14 N of downward pressure while operating more quietly than the previous generation. In addition, threshold-crossing capability has been improved. The robot can now overcome double-layer thresholds up to 4.5 cm + 4.3 cm, allowing it to move smoothly over door sills, sliding door tracks, etc.

  • What improvements have been made to the new VibraRise® 5.0 mopping system?

    The VibraRise® 5.0 system has removed Edgewise mopping module and adopts an extendable mop design to clean corners and edges more effectively. The downward pressure of the mop has been increased to 14 N. When combined with 4,000 vibrations per minute, it delivers more thorough removal of stubborn stains. In addition, overall system noise has been significantly reduced, making cleaning quieter.

  • How has the Saros 20 Sonic been improved for carpet cleaning?

    The Saros 20 Sonic features a brush stabilization module that works in conjunction with the AdaptiLift™ Chassis 3.0 multi-stage lifting system. This combination keeps the main brush in a precisely controlled position, improving carpet-cleaning performance and significantly enhancing the pickup efficiency of larger debris.

  • What new features or upgrades does the docking station offer?

    The docking station introduces the industry's first independent mop washing system, supporting mop washing at temperatures of up to 100°C, along with further optimized drying performance. A new 55°C warm-air dust-bag drying function has also been added to help inhibit odors and bacterial growth. Together, these upgrades significantly improve both cleaning efficiency and hygiene.

  • How well does the robot handle thresholds? What types of thresholds can it cross?

    The Saros 20 Sonic supports a maximum threshold crossing height of 8.8 cm, making it suitable for various home environments. It can easily cross single thresholds such as door sills up to 4.5 cm, as well as double-layer thresholds like sliding door tracks combined with door sills up to 4.5 cm + 4.3 cm. This allows it to adapt smoothly to sliding doors and other complex conditions.

  • Does it support carpet detection and automatic mop lifting?

    Yes. With the AdaptiLift™ Chassis 3.0 intelligent lifting system, the robot automatically detects carpets and lifts the mop to prevent wetting carpets. When combined with main-brush stabilization and downward pressure control, it delivers deeper and more effective carpet cleaning in Vacuum Only mode.

  • What navigation and obstacle-avoidance features does the Saros 20 Sonic offer?

    The robot retains RetractSense™ retractable LiDAR navigation and is equipped with the Reactive AI 3.0 obstacle avoidance system, which integrates tri-laser structured light, an RGB camera, and a VertiBeam side laser. This advanced sensing setup enables highly accurate object recognition, faster avoidance responses, and the ability to remember remember the positions of frequently encountered obstacles. As a result, the robot delivers smarter path planning and more efficient cleaning.

  • How about the battery life and charging performance of the Saros 20 Sonic?

    The Saros 20 Sonic is powered by a 6,400 mAh high-performance battery, providing up to 180 minutes of runtime in Vac & Mop mode with Balanced suction power. It features fast-charging protection technology and can recharge from 15% to 100% in approximately 2.5 hours, balancing charging efficiency with long-term battery health.

  • How many colors are available for this model? Does the robot still maintain its slim design?

    The Saros 20 Sonic is available in classic black and in white. The machine retains its ultra-thin 7.98 cm design, enabling it to move easily beneath sofas, beds, and other low-clearance furniture for comprehensive cleaning coverage.
