The vacuum robot that “walks”: Roborock Saros Rover surprises CES 2026

In Las Vegas, Roborock arrived at CES 2026 with an eyebrow-raising announcement: the Saros Rover, touted as the world’s first robot vacuum combining “legs and wheels”. The idea is straightforward and notably less simple to achieve: to clean in places where robots usually abandon, notably stairs, slopes, and complex thresholds.

The brand also took the opportunity to unveil its “first half of 2026” range with several new robot vacuum models (Saros 20, Saros 20 Sonic, Qrevo Curv 2 Flow) and a new stick vacuum-mop (F25 Ace Pro). As if that weren’t enough, Roborock is also bringing new robotic lawn mowers to the garden, including a LiDAR version.

Saros Rover: legs, wheels, and (finally) stairs in sight

The Saros Rover is the “world first” highlighted by Roborock. Its principle relies on a dual “leg-wheel” system, where each module can raise, lower, and lift independently.

Roborock explains that the robot can perform small jumps, rapid turns, sudden stops, and precise direction changes while maintaining its stability despite varying floor conditions. We filmed it at CES.

The key point is the “multi-level” ambition: the Rover is designed to climb stairs and clean each step along the way to the upper floor. Roborock also mentions the ability to navigate on curved stairs, steps with carpeting and nosing, and to manage slopes as well as multi-level thresholds that require both height… and torque.

On the intelligence side, Roborock talks about advanced AI algorithms, motion sensors, and 3D spatial modeling to analyze the environment and adjust movements precisely.

Note: the Saros Rover is announced as a product still in development, with no launch date communicated at this stage. But the technical prowess is interesting!

Saros 20: XXL crossing, navigation AI, and RockDock station that heats to 100°C

In the new Saros series, the Roborock Saros 20 relies on an AdaptiLift 3.0 chassis designed to overcome “difficult” thresholds, including double-level thresholds up to 8.5 cm total (4.5 cm + 4 cm), and up to 4.5 cm on a single threshold. Roborock also highlights dynamic lifting of the chassis on carpets (up to 3 cm of pile height when activated in the app) to maintain suction and brush contact. The cherry on top, the robot can raise its chassis at the front, back, left, or right to free itself from a “trap” without intervention.

For navigation, Roborock introduces StarSight 2.0, a 3D platform meant to map faster and improve obstacle avoidance, recognizing more than 200 types of objects/obstacles. All this with a sampling rate reported to be 21 times higher than that of a traditional LDS, and a side system, VertiBeam, to stay well aligned along walls and limit the risk of tangling (cables, irregular shapes). The Saros 20 also has a height of 7.98 cm, convenient for passing under beds and sofas.

On the cleaning side, we find the HyperForce suction rated at 35,000 Pa, plus a duo of rotating mops (up to 200 rpm) with adaptive pressure that can increase when tougher stains are detected. Roborock also mentions StainTarget AI Cleaning, capable of adjusting the strategy depending on whether the dirt is “dry” or “wet”, and an anti-tangling approach with the DuoDivide main brush and FlexiArm Arc side brush, designed for long hair and pet fur.

Finally, the new RockDock station clearly emphasizes maintenance: washing mops with hot water up to 100 °C, hot air drying at 55 °C, automatic emptying with up to 65 days between bag changes, automatic detergent distribution, and even a version with integrated filling/emptying (depending on regions/countries, with water supply and drainage constraints).

Announced availability: first quarter of 2026 on the Roborock site and Amazon, with “Saros 20 Set” and “Saros 20X” variations based on the channels.

Saros 20 Sonic: extendable sonic mop, retractable LiDAR, and offline “Hello Rocky”

The Roborock Saros 20 Sonic stands out for its washing approach: VibraRise 5.0, with an extendable sonic mop that can scrub at 4,000 vibrations per minute, and a pressure reported up to 14 N. Roborock also indicates a vibration surface 27% larger than its previous vibrating models, and especially edge-to-edge work with a head that physically extends to reach baseboards, up to 0 mm along the edge according to internal testing.

It also includes AdaptiLift 3.0 for overcoming (up to 8.5 cm on double level), and a dynamic cleaning mode for carpets up to 3 cm, with a reported gain in dust pick-up on long pile carpets. For suction, it remains at HyperForce 35,000 Pa, with a reported anti-tangling system capable of handling strands up to 40 cm, and internal results claiming 0% tangling and 100% hair removal.

The clever “engineering” point is the RetractSense navigation: to maintain a total height of 7.98 cm, the main LiDAR retracts automatically under low furniture while preserving a 100° rear view to continue mapping and exit low clearance areas. The avoidance relies on Reactive AI 3.0 (triple structured light, RGB camera, VertiBeam). And for control, Roborock integrates “Hello Rocky”, an offline built-in voice assistant, as well as Matter support for smart home integration (Alexa, Siri, Google Home).

Announced availability: first quarter of 2026 on the Roborock site and Amazon, with a “Saros 20 Sonic Complete” pack at retailers.

Qrevo Curv 2 Flow: a roller robot, real-time self-cleaning, and carpet protection

With the Qrevo Curv 2 Flow, Roborock pushes a format still rare in robotics: washing with a motorized roller. The roller is reported to be extra-large (270 mm), spinning up to 220 rpm, with a downward pressure of 15 N, and a clear goal: to quickly remove splashes on hard floors and mixed surfaces (coffee, ketchup, mud). The core system is called SpiraFlow: during cleaning, the roller is continuously washed, with eight hydration points providing clean water, while a scraper manages the moisture and sends dirty water to a separate tank to limit cross-contamination. Roborock highlights bacteria tests (up to >99.99% according to TÜV SÜD) on the roller.

For edges, Edge-Adaptive allows the roller to extend to approach walls and chair legs, up to 10 mm. And for carpets, Roborock adds a “Roller Shield” (physical barrier) and a mechanism that lifts the roller by up to 15 mm and covers it when approaching textile areas, to keep carpets dry.

On the suction side, the Qrevo Curv 2 Flow claims up to 20,000 Pa in Max+, and a software adaptation DirTect AI: the robot adjusts its strategy based on the type of dirt, increases suction on dust, and can switch to washing alone on wet splashes by raising certain brushes to limit contamination. Obstacle avoidance is achieved through Reactive AI (structured light + RGB camera), recognizing over 200 types of obstacles, with a reported ability to detect objects from about 5 cm wide and 3 cm high.

The station also evolves: separation of clean/dirty water on the tray, high-temperature roller washing (75 °C reported, with claims of bacterial elimination), hot air drying at 55 °C, and automatic emptying for up to 65 days. Regarding “smart home,” Roborock talks about multiple Wi-Fi profiles, Matter support, voice assistants, SmartPlan 3.0, and even pet-oriented features (photos during cleaning, video calls).

Availability: first quarter of 2026 on the Roborock site and Amazon, with a “FlowX” version at retailers (additional accessories).

F25 Ace Pro: the stick vacuum-mop focused on foam and anti-tangling

Alongside the robots, Roborock highlights a new stick vacuum-mop: the F25 Ace Pro. Its “signature” is JetFoaming, a technology that transforms 1 ml of foaming cleaning solution into 167 million microbubbles, supposed to adhere to stains (grease, sticky residues, toothpaste…) to dissolve and lift them. Activation is done through a held button, and the foam is sprayed at the front to be spread in a uniform layer.

The F25 Ace Pro announces 25,000 Pa of suction, a downward pressure of 30 N, and a brush speed of 430 rpm. It also includes a DirTect sensor to adapt suction and water flow in Auto mode. On the edges, Roborock claims “0 mm” cleaning thanks to edge-to-edge coverage on both sides (with a note specifying that these are internal tests).

The issue of hair/fur is clearly addressed: JawScrapers, a “shark teeth” cleaning blade with constant pressure scrapers. Roborock cites SGS tests with 0% tangling and more than 90% hair elimination on a protocol involving 2,000 strands of 50 cm. And for maneuverability, we find SlideTech 2.0 (smart double motor push-pull wheels) and FlatReach 2.0, capable of tilting the device to 180° flat while maintaining suction, with a reported height of 12.5 cm to pass under furniture.

The maintenance station aims for “hands-free”: high-temperature washing 95 °C to break down grease/residues and limit bacteria, with a claim of 99.99% bacterial elimination (TÜV SÜD tests). Then hot air drying at 95 °C, a reported silent cycle at 48 dB, in 30 minutes. The app also allows remote control and detergent level adjustments.

Price and availability: €649 with commercialization in January 2026.

Roborock also goes for the garden: RockMow X1 LiDAR, RockMow X1, and RockNeo Q1

Roborock continues to expand its portfolio with a new range of robotic lawn mowers, officially announcing its entry into the American robotic lawn mower market, with a rollout planned for 2026 (United States and other markets). The highlighted model is the RockMow X1 LiDAR, presented as the first Roborock robotic mower based on LiDAR technology, combined with Sentisphere, a four-wheel drive system, patented active steering, and dynamic suspension, for simplified installation and cutting “to the edges”.

Next to it, the RockMow X1 combines centimeter-precise RTK and VSLAM navigation with 4WD traction, patented active steering, and dynamic suspension.

Finally, the RockNeo Q1 aims for the entry-level market, with Sentisphere, multi-band RTK + VSLAM navigation, obstacle avoidance through stereo vision, and an optional PreciEdge cutting module.

Roborock specifies that the prices, availability, and features of the lawn mowers marketed in France will be announced in the first quarter.

What to remember: Roborock focuses on three very clear axes

The first axis is access to “impossible” areas: Saros Rover aims directly at stairs, while Saros 20 / Saros 20 Sonic put a strong emphasis on overcoming thresholds and ground clearance on carpets via AdaptiLift 3.0.

The second is automated maintenance and hygiene: hot water (up to 100 °C on RockDock), hot air drying, more advanced cleaning cycles, and reported dust bag autonomy of up to 65 days depending on the models.

The third is the specialization of washing systems: roller with continuous cleaning on Qrevo Curv 2 Flow, extendable sonic mop on Saros 20 Sonic, JetFoaming foam on the F25 Ace Pro. Three different approaches, three ways to attack everyday stains… and that, frankly, was quite exciting to follow at the show!
