Roborock Robot Vacuum and Mop Saros 20 Sonic
Roborock Robot Vacuum and Mop Saros 20 Sonic is a premium smart cleaning solution designed for powerful vacuuming, advanced mopping, intelligent navigation, and convenient hands-free maintenance. With an impressive 36,000Pa suction power, hot-water sonic vibration mopping, AI-powered obstacle recognition, precise LiDAR navigation, and an advanced RockDock Ultra system, the Saros 20 Sonic is built to deliver a deeper and smarter clean.
Its ultra-thin 3.14-inch design allows the robot to reach low spaces and difficult areas under furniture. The retractable LDS system, RGB camera, and ToF sensor work together to improve dirt detection and navigation, even in tight or low-light areas.
Roborock Robot Vacuum and Mop with 36,000Pa Suction
The Saros 20 Sonic delivers up to 36,000Pa powerful suction, helping remove dust, dirt, crumbs, debris, pet hair, and other everyday messes from your floors. Its tangle-free main brush is designed to reduce hair wrapping and keep cleaning performance consistent.
The anti-tangling design makes this robot especially useful for homes with pets and long hair. It combines strong suction with intelligent cleaning technology to provide effective cleaning across different floor surfaces.
Hot Water Sonic Vibration Mopping
The advanced mopping system is designed to tackle stubborn stains and everyday marks. Its Hot Water Sonic Vibration Mopping technology can deliver up to 4,000 vibrations per minute, helping loosen dirt and stains more effectively.
The retractable anti-tangling side brush and lifting anti-tangling side mop help improve edge and corner cleaning. This allows the Saros 20 Sonic to clean closer to walls, furniture, and other hard-to-reach areas.
The combination of powerful vacuuming and advanced sonic mopping makes the Roborock Robot Vacuum and Mop a convenient all-in-one cleaning solution for modern homes.
Ultra-Thin 3.14-Inch Design
The Saros 20 Sonic features an ultra-slim body measuring approximately 3.14 inches in height. Its retractable LDS system helps the robot adapt its navigation system when cleaning underneath furniture and in tight spaces.
The top-mounted ToF sensor automatically adjusts the LDS height while maintaining a wide viewing angle. Combined with the RGB camera, this technology helps the robot detect dirt and navigate challenging areas more effectively.
The slim profile makes the Saros 20 Sonic suitable for cleaning under beds, sofas, cabinets, and other furniture with limited clearance.
Reactive AI 3.0 Obstacle Recognition
The Saros 20 Sonic features Reactive AI 3.0 for advanced obstacle recognition. Its perception system combines front triple structured light, an RGB camera, and VertiBeam lateral structured light technology.
VertiBeam helps the robot identify side obstacles and navigate around furniture, household items, and other objects. The system continuously adapts to the surrounding environment, allowing the robot to respond quickly as it moves through your home.
Precise obstacle detection helps reduce collisions while maintaining efficient cleaning coverage around furniture and other objects.
Precise LiDAR Navigation
Advanced LiDAR navigation helps the Saros 20 Sonic understand the layout of your home and plan efficient cleaning routes. The robot can intelligently navigate rooms and avoid obstacles while working toward thorough floor coverage.
Its combination of LiDAR, structured light, RGB imaging, and smart sensors provides accurate navigation in complex home environments.
New Generation RockDock Ultra
The RockDock Ultra provides automated maintenance to reduce the amount of manual work required after cleaning. The docking station supports 212°F hot-water mop washing, dynamic temperature adjustment, and 140°F heated-air drying.
The dock also features self-cleaning with warm water, intelligent dirt detection, automatic detergent dispensing, automatic water refilling, fast charging, and off-peak charging.
These automated functions help keep the robot ready for its next cleaning session while minimizing daily maintenance.
Smart Voice Assistant Integration
The Saros 20 Sonic supports convenient voice control. With the compatible voice assistant functionality, users can issue commands to start cleaning, clean specific areas, skip rooms, empty the dustbin, clean the dock, and perform other supported functions.
It supports integration with Alexa, Siri, and Google Home, allowing you to control your robot using compatible smart-home devices.
The Saros 20 Sonic also supports Matter 2.0 compatibility, helping integrate the robot into compatible smart-home ecosystems.
Pet-Friendly Robot Vacuum and Mop
For homes with cats and dogs, the Saros 20 Sonic offers useful pet-focused features. Its powerful 36,000Pa suction helps collect pet hair, dust, dander, and debris from floors.
Pet Snaps and Video Call & Cruise features allow users to check on their pets remotely when supported. Smart cleaning algorithms can also focus on high-traffic areas around pet feeding and supply zones.
This makes the Saros 20 Sonic a practical choice for pet-friendly households that need frequent automated cleaning.
Smart Cleaning for Large Homes
The Saros 20 Sonic is designed for substantial cleaning areas, with a specified living area coverage of up to 340m². Its battery provides up to 190 minutes of running time, depending on cleaning mode and environmental conditions.
With smart navigation, automatic charging, and automated dock maintenance, the robot can handle regular cleaning with minimal user intervention.
