Roborock presented its latest robotic cleaning solutions at CES in Las Vegas, including the Saros Rover, a prototype for a stair-climbing robotic vacuum, along with updated models in its Saros and Qrevo series. The company also introduced a new handheld wet/dry vacuum and expanded its product portfolio to include robotic lawnmowers.
Saros Rover: Stair-Climbing Robotic Vacuum
The Saros Rover, currently a prototype under development, was previewed as a wheel-leg robotic vacuum designed to navigate and clean stairs. It features hinged legs, each equipped with a wheel, capable of independent operation. Software is intended to maintain balance and level orientation, allowing the Rover to ascend and descend stairs, including curved staircases, and clean each step. It is also designed to climb ramps.
According to Katie Leonowitz, Roborock's public relations manager for North America, the Saros Rover is positioned as the first robot model capable of cleaning stairs while actively climbing them. This feature aims to address cleaning challenges in areas between floors that traditional robotic vacuums cannot access. Roborock anticipates further improvements over the next year, with potential availability projected around 2027. Details regarding pricing and a closer retail launch date are pending.
New Robotic Vacuums: Saros Series
Roborock introduced two new models in its Saros series: the Saros 20 and Saros 20 Sonic.
Saros 20The Saros 20 incorporates Roborock’s AdaptiLift Chassis 3.0 system, which facilitates transitions over obstacles up to 3.3 inches in height. Navigation is managed by the StarSight Autonomous System 2.0, which generates 3D home maps and is designed to identify over 200 object types for obstacle avoidance. The vacuum offers 35,000 Pa suction power and includes a FlexiArm for cleaning close to edges. Its mopping function utilizes dual heads that spin at up to 200 RPM with 12N downward pressure. The accompanying RockDock provides cleaning capabilities for the mop with 212°F water, followed by 131°F warm air drying.
Saros 20 SonicThe Saros 20 Sonic retains the AdaptiLift climbing system and vacuum capabilities of the Saros 20. It is designed for confined spaces, with a height of 3.1 inches, and can temporarily retract its LiDAR sensor to pass under furniture, using its cameras for navigation. A primary feature is its VibraRise 5.0 Mopping System, which vibrates up to 4,000 times per minute. It features a single mop head designed to clean floor edges without gaps and applies 14N of downward pressure. Pricing and availability for both Saros 20 models are expected to be announced in 2026.
Qrevo Curv 2 Flow
The Qrevo Curv 2 Flow delivers 20,000 Pa suction and features a continuously self-cleaning SpiraFlow mop. The mop's 10.6-inch roller spins at up to 220 RPM and applies 15N of pressure. The device's onboard intelligence is designed to adapt cleaning strategies based on detected mess types, switching between vacuuming and mopping as needed. Its dock supports over two months of use before dust bin emptying is required and includes 167°F water cleaning and 131°F warm air drying for the mop. The Qrevo Curv 2 Flow also includes pet recognition features and supports remote video calls. Sales are scheduled to begin on January 19, 2024, with an introductory price of $849, which will increase to $999 in February.
F25 ACE Pro Handheld Wet/Dry Vacuum
The F25 ACE Pro is a handheld wet/dry vacuum offering 25,000 Pa suction. Its wet cleaning function combines 430 RPM rotation speed with 30N downward pressure and an enlarged water tank. The device can generate ultra-dense foam for certain cleaning tasks. For maintenance, it includes hair-rejection scrapers. The base dock provides 203°F high-temperature washing and 203°F hot-air drying. Sales commence on January 19, 2024, at an initial price of $549, which will rise to $699 in February.
Expansion into Outdoor Robotics
Beyond indoor cleaning devices, Roborock is expanding its product portfolio with new robotic lawnmowers. Three models were introduced, which utilize satellite navigation and lidar technology for managing various yard sizes and complexities. These lawnmowers feature four-wheel drive, enabling them to ascend terrains described as steep.
Company Approach and Industry Context
Roborock attributes its product development to a core philosophy centered on artificial intelligence (AI) as the underpinning for its technology. This AI, combined with lidar-based mapping, allows its machines to perceive environments and adapt. Other companies also showcased robot vacuum innovations at CES, including Ecovacs Robotics with new DEEBOT models featuring enhancements such as stain pretreatment, Samsung's Bespoke AI Jet Bot Steam Ultra with advanced navigation, and LG, which presented a model with a built-in station designed to fit under kitchen counters, receiving a CES Innovation Award.
