Roborock has demonstrated a robot vacuum that can climb and clean stairs, but the machine is the Saros Rover—a product still described as being in development. The Roborock Saros 20, which is available to buy, can cross unusually high thresholds and reach edges and corners. It is not a robot that climbs an ordinary flight of stairs.
The Saros Rover is the stair-climbing model
Roborock introduced the Saros Rover at CES 2026 in Las Vegas on January 6. The company describes it as its first robot vacuum built around an AI-powered wheel-leg architecture and says it can navigate slopes, staircases and other changing terrain.

Unlike a conventional robot vacuum, the Rover uses two wheel-legs mounted on independently moving, extendable mechanisms. The legs are intended to lift and reposition the body as the robot moves from one tread to the next, while keeping the main body relatively level. Roborock says its motion system combines sensors, 3D spatial data and AI algorithms to coordinate climbing, turns, stops, directional changes and small jumps.
Most importantly, Roborock says the Rover is designed to clean each stair step while ascending. That makes it substantially different from a carrier, lift or accessory that merely transports a normal robot vacuum between floors.

Can you buy the Saros Rover?
Not according to the available launch information. Roborock presented the Saros Rover as a demonstration and product in development, and no confirmed retail release date or price has been announced in the cited coverage. Vacuum Wars and Tom’s Guide both reported that availability had not been confirmed.
The CES demonstration shows the direction of Roborock’s technology, but it is not the same as an independent long-term test in a typical home. There is not yet enough information to confirm how reliably the Rover handles traction loss, missed steps, damaged treads, pets or people on the staircase, or a failed climb.
What kinds of stairs might it handle?
Coverage of the demonstration says Roborock has positioned the Rover for conventional and curved staircases, slopes, carpeted stairs with bullnose fronts, uneven terrain and complex multilevel transitions. Those are claimed or demonstrated use cases—not a guarantee that the robot will work safely on every staircase.

- Maximum riser height or staircase angle
- Minimum tread depth
- Carpet thickness or loose carpet
- Wet, polished or damaged steps
- Open-riser, floating, spiral or unusually narrow stairs
- Railings, obstructions and fragile trim
Before treating the Rover as a solution for a multilevel home, buyers would also need clear answers about fall prevention, safety boundaries, recovery after a failed climb, battery capacity, mapping between floors, and whether the dock can remain on a different floor.
The Saros 20 is a different robot
The confusion comes partly from Roborock announcing the Saros Rover alongside the commercially available Saros 20. The Saros 20 is a premium floor-cleaning robot with a lifting chassis, but its capability is designed for thresholds—not full staircases.

Roborock’s AdaptiLift Chassis 3.0 is rated to cross a single threshold up to 1.77 inches, or 4.5 cm. The company also lists double-layer threshold capability of approximately 3.46 inches, although the individual figures vary slightly between its announcement and product page. These measurements are useful for raised door tracks, floor transitions and similar obstacles. They should not be described as the ability to climb a normal flight of stairs.

The Saros 20 is listed on Roborock’s U.S. store at $1,599.99. Its other published specifications include:
- Manufacturer-rated suction of up to 36,000 Pa
- FlexiArm side-brush and mop extension for edges and corners
- Navigation under spaces as low as 3.13 inches
- Dynamic carpet cleaning for pile up to 1.18 inches
- Hot-water mop washing up to 212°F (100°C)
The listed suction figure is a manufacturer rating, not a standardized real-world pickup score that can be directly compared across brands.
What “deep-cleans corners” means
For the Saros 20, corner cleaning mainly refers to Roborock’s FlexiArm system. The side brush can extend toward edges and corners, while the mop can extend along edges to reduce the uncleaned strip that many robot vacuums leave beside walls or furniture.
That does not mean the Saros 20 can scrub vertical baseboards, stair risers or every three-dimensional crevice. Edge reach is different from cleaning a vertical surface. It also does not connect the Saros 20’s corner-cleaning feature to the Rover’s stair-climbing concept; they are separate products with different purposes.

What testing says about the Saros 20
In a several-week home test, Tom’s Guide reported strong vacuum performance on pet hair, dust, crumbs and other debris. The vacuum function was the strongest part of the product in that review.
Rank #3
- Fits Pet Owners and Hard Floors: With a tangle-free suction port, V2 robot vacuum focuses on picking up hair without tangle; It also tackles dirt, crumbs and debris effectively on hardwood, tile, laminate, stone and low pile carpet
- Ultra-Slim Design: The 2.99-inch low profile allows the V2 robot vacuum cleaner to easily clean under beds, sofas, and other furniture
- Friendly Remote Control: The V2 vacuum robot equipped a physical remote control, no Wi-Fi connection is required for operation. Start cleaning easily via the remote or one-touch button, simple to operate for all family members

- Schedule Cleaning & Automatic Charging: V2 vacuum robot can run routine cleaning automatically based on preset schedule, it cleans up to 120 minutes on a single charge and automatically returns to the charging dock when the battery is low
The same review found the mopping less consistent, describing results as somewhat streaky and patchy. That matters if the main reason for considering the Saros 20 is automated mopping rather than vacuuming, threshold crossing or edge reach. Tom’s Guide reported a U.S. release date of March 23, 2026, with a $1,599.99 MSRP; buyers should verify current availability and pricing on Roborock’s store.

Wait for the Saros Rover if:
- Your main problem is moving a robot between floors.
- You have long staircases that you want cleaned automatically.
- You are comfortable waiting for an unpriced, not-yet-confirmed retail product.
- You are willing to evaluate first-generation reliability and safety information when it becomes available.
Choose the Saros 20 if:
- You want a premium robot vacuum for ordinary floors now.
- Your home has raised thresholds rather than full staircases to climb.
- Edge and corner reach, low-clearance navigation and dock automation are priorities.
- You value strong vacuum performance and accept that mopping may be less consistent.
Use another arrangement if stairs are the immediate need
For a multistory home today, one conventional robot per floor is more practical and proven than buying the Saros 20 expecting it to climb stairs. A handheld or stick vacuum remains the dependable choice for stair treads, risers, upholstery and tight vertical corners. A conventional premium robot is also the better value when the home is mostly single-level and the main task is removing everyday floor debris.
Questions Roborock still needs to answer
The Rover’s headline capability is promising, but a finished product would need to document more than a successful demonstration. Buyers should look for published limits and testing covering:
- Maximum riser height, tread depth and slope
- Open-sided and floating stairs
- Wet, glossy, loose or damaged surfaces
- Fall detection and recovery procedures
- Behavior around children and pets
- Battery use and dust capacity over multiple floors
- Charging, emptying, mapping and resuming after a floor change
- Maintenance, replacement parts and support
Until those details and a retail launch are confirmed, “robot vacuum that climbs stairs” should be understood as a description of the Saros Rover concept—not a feature of the Saros 20 currently sold in the United States.
Bottom line
Roborock really has shown a robot vacuum designed to climb and clean stairs: the Saros Rover. But it remains a development-stage product with no confirmed price or retail date in the available reporting. The Saros 20 is the model buyers can purchase, and it offers impressive threshold crossing and FlexiArm edge cleaning—not full-stair climbing.
