Roborock has pulled the curtain back on the Saros 20, its latest flagship robotic vacuum and mop designed to handle the kind of real-world obstacles that typically stop robovacs in their tracks. Introduced as part of the brand’s CES 2026 lineup, the Saros 20 leans hard into autonomy, mobility, and self-maintenance, aiming to reduce the number of times owners need to intervene mid-clean.
At a glance, Saros 20 is a premium robot vacuum and mop built for mixed flooring, deeper carpets, and busy homes with thresholds, rugs, pets, and clutter. Under the hood, it pairs a new adaptive chassis with upgraded navigation, stronger suction, and a significantly more capable docking station.
AdaptiLift Chassis 3.0 Targets Real-World Obstacles
One of the Saros 20’s headline upgrades is the new AdaptiLift Chassis 3.0. Instead of relying on fixed wheels, the system combines liftable main and auxiliary wheels with a climbing arm that actively analyzes floor transitions. The result is support for double-layer thresholds totaling up to 3.3 inches, which covers many door frames, step-downs, and uneven transitions found in older homes.
The chassis can also dynamically raise and lower itself during cleaning. On carpets, Saros 20 lifts its body to maintain suction and brush contact on rugs up to 1.18 inches tall, while adjusting wheel height independently if it needs to free itself from a tricky spot. The goal is simple: fewer rescues, fewer “robot stuck” notifications.
StarSight Autonomous System 2.0 Improves Mapping and Avoidance
Navigation duties fall to the StarSight Autonomous System 2.0, Roborock’s latest vision-based platform. It maps faster than traditional laser-based systems and recognizes more than 200 types of common household objects, including cables, pet toys, and small obstacles that typically require pre-tidying.
Roborock says the system samples its surroundings at a much higher frequency than LDS navigation, improving path accuracy and edge alignment. A slim 3.14-inch body height allows the Saros 20 to clean under low furniture, while side-facing sensing helps it follow walls and furniture lines with tighter precision.
Vacuuming and Mopping Adapt to the Floor Beneath
Saros 20 uses a triple-lift design that coordinates the chassis, main brush, and dual spinning mops in real time. On carpet, the mops lift or detach to keep fabrics dry while the brush and suction focus on debris removal. For hard floors, the main brush can lift during wet mopping to reduce dust streaking.
Vacuum power tops out at 35,000 Pa, paired with Roborock’s Dual Anti-Tangle System to manage long hair and pet fur. For mopping, the dual spinning pads rotate up to 200 times per minute and apply increased downward pressure when tougher stains are detected. A mop-only mode can be enabled for liquid messes to avoid spreading debris.
Edge cleaning gets extra attention via the FlexiArm system, which extends to reach baseboards and corners that many robot vacuums leave behind.
A New RockDock Focuses on Hands-Free Ownership
The redesigned RockDock is doing a lot of heavy lifting. It washes mops with hot water up to 212°F, dries them with warm air, empties dust automatically for up to 65 days, refills water, and dispenses detergent. There’s also an optional refill and drainage configuration for households that want fully automated water management, pending regional availability and installation requirements.
Fast charging rounds out the package, helping Saros 20 spend more time cleaning and less time parked.
App Features, Smart Controls, and Availability
Control runs through the Roborock app, where SmartPlan 3.0 adapts routines based on room type, floor material, and usage patterns. Users can fine-tune carpet behavior, enable advanced stain targeting, and integrate the robot into broader smart home setups via Matter, Alexa, Siri, or Google Home.
Roborock says the Saros 20 will roll out internationally in 2026. Pricing and regional availability have not been announced yet. More details can be found on Roborock’s official website as launch timing approaches.
