Support for your Roborock Saros 20 Sonic

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.

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.

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.

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.

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.

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 the positions of frequently encountered obstacles. As a result, the robot delivers smarter path planning and more efficient cleaning.

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.

The Saros 20 Sonic offers some major noise reduction features:

1. In Mop Only mode, the noise level is as low as 55 dB, comparable to a quiet library.
2. In Vac & Mop mode with Balanced suction power, the noise level (63 dB) is similar to the hum of a refrigerator or the sound of normal conversation. You will notice the robot working, but you won't find it noisy.
3. The docking station has been also optimized for noise reduction. Mop washing operates at around 57 dB, and warm-air drying is exceptionally quiet at just 43 dB. When auto-emptying, noise temporarily increases to 74 dB, similar to a high-power vacuum cleaner, but lasts less than a minute.

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.

Both models are Roborock flagship products and share key specifications, including 36,000 Pa ultra-high suction, 8.8 cm double-layer threshold crossing, the AdaptiLift™ Chassis 3.0 lifting system, 100°C hot-water mop washing, and dust-bag drying. The primary differences lie in the mopping system and navigation system with obstacle-avoidance technologies:

1. The Saros 20 Sonic features the VibraRise® 5.0 high-frequency vibrating mopping system, with an extendable mop that applies 14 N of downward pressure, suitable for users who prefer intensive, pressure-based floor scrubbing.
2. The Saros 20 is equipped with a dual rotating mopping module, which uses two high-speed spinning mop cloths to simulate manual scrubbing.

In terms of navigation, both models accurately detect common household obstacles and plan efficient cleaning routes, but they rely on different sensing technologies:

1. The Saros 20 Sonic 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 to deliver stereoscopic environmental perception.
2. The Saros 20 uses the StarSight vision recognition system, which offers exceptional visual detection and identification capabilities.

Both models deliver premium performance in suction power, obstacle handling, and docking station functionality. The best choice for you depends primarily on your preferred mopping method.
