Rock showcased a dual-legged sweeping robot at CES: can climb stairs and jump, release date undetermined.

```

Roborock has launched a stair-climbing robot vacuum cleaner, in an attempt to revitalize its home robot strategy after last year’s lukewarm performance of its robotic arm product.

On Tuesday, Roborock showcased a concept product equipped with two legs that can climb stairs at this year's technology conference CES.

This device, called Saros Rover, is the first robot vacuum cleaner equipped with double-wheeled legs. The two legs can rise and descend independently, allowing it to climb stairs, traverse uneven surfaces, and perform emergency stops and minor turns while moving.

This year's CES conference centers around robotics technology, and the organizers have set up a dedicated exhibition area for this category. However, high prices and practicality issues remain key obstacles to large-scale adoption. The company's robotic arm product, launched last year, received a lukewarm market response.

Questions on battery life and emergency capability

Rover navigates by combining artificial intelligence, multiple motion sensors, and 3D spatial information.

According to Bloomberg, in a media demonstration prior to Tuesday’s release, it successfully climbed several steps, rolled down a slope, and performed a small jump. A company spokesperson said that this move could be used to descend stairs or bypass certain obstacles.

However, similar to the previous Z70, Rover moves slowly when standing on its legs—slower than traditional robot vacuums that remain close to the ground at all times. Roborock has not revealed how long the device can operate on a single charge.

The carefully arranged demonstration did not immediately show what would happen if Rover fell over, or whether it could adjust its direction by itself without human assistance.

Apart from Roborock’s household appliance products, multiple brands will showcase humanoid robots at CES, some of which claim to be capable of completing complex multi-step tasks, such as sorting and folding clothes.

But the technology still faces many challenges before entering mainstream use, most notably the high cost of machines with complex mechanical structures like Rover.

Companies also need to make progress in enhancing mobility and battery life to a level where consumers feel comfortable entrusting household tasks to robots.

Learning from past failures, launch timing remains uncertain

At last year's CES, Roborock became an unexpected focal point with the Saros Z70, a robot vacuum equipped with a robotic arm that could pick up socks.

Although the device stunned audiences with meticulously choreographed demonstrations at the show, tech reviewers responded coolly when it was launched in the United States months later at a price of $2,599.

In addition to its steep price, a common criticism was that the Z70 could only recognize a few types of items, such as tissues, paper, and slippers, but failed to identify children’s toys or pet toys.

After that unsuccessful launch, Roborock has adopted a different strategy with the two-legged Rover. According to reports quoting the company, the launch date for this product has not been determined yet.
