Roborock Saros Z70 Launched With an Arm That Can Pick Up Trash

At CES 2025, Roborock took robot vacuum technology to the next level, equipping its latest flagship, the Saros Z70, with an actual, movable robotic arm. Unlike the small appendage seen on the S8 MaxV Ultra at CES last year, this arm protrudes from the middle of the machine and can be extended to pick up items like socks and paper towels while mopping. While it’s still a little creepy and currently extremely slow, the potential of a robot vacuum that can clean itself before cleaning is undeniable.

The Verge had a chance to experience the Saros Z70 in person before its launch, confirming that the robotic arm works as advertised, albeit slowly. In the demo, it took the robot about a minute to pick up and move each sock. Pickup is also limited to socks, tissues, small towels, and slippers weighing less than 300 grams. 

Roborock says it will add more collectibles in the future, but hasn’t promised any weight increases. Pricing for the Saros Z70 hasn’t been announced yet, but it’s expected to hit shelves in June 2025.

According to Roborock, the Saros Z70 arm is “the first mass-produced foldable robot arm with five axes.” Dubbed OmniGrip, the arm can unfold, extend, and rotate both horizontally and vertically to pick up objects and move them out of the way. The arm is equipped with a camera and LED lights for vision, along with sensors to detect the weight and position of objects, including whether there are any obstacles above, to ensure safety during operation.

The Saros Z70’s operating procedure is quite complex. On its first run, the robot detects and marks the objects that can be picked up. It then turns around, deploys its arms, moves the objects to the cleaned area, and proceeds to clean the hidden area. 

Finally, the robot can be programmed to make a third move, picking up items and placing them in a user-specified location on the map in the Roborock app, such as near a closet or in a shopping cart.

While this whole process is time-consuming and it would be quicker to pick up your socks yourself (if you’re at home), there’s no denying the fun of having a robot pick up your socks for you. We’re truly living in the future!

In addition to its unique robotic arm, the Saros Z70 also has another cool feature that comes with an OTA upgrade. This feature takes advantage of the new StarSight Autonomous System 2.0 for location and obstacle recognition, allowing users to "train" the robot to recognize specific objects, such as a favorite stuffed animal or wallet. The Roborock app will display the last location where the robot detected the object, making it easier for users to find lost items.

StarSight, which first appeared on the Qrevo Slim, uses a 3D ToF sensor, an RGB camera, and machine learning to navigate and identify obstacles. According to Roborock, AI-powered machine learning allows the Z70 to detect and navigate up to 108 pre-programmed objects. The robot is also equipped with new VertiBeam obstacle avoidance technology that uses lasers to help clean more precisely around cables, walls, and irregularly shaped furniture.

Other impressive specs of the Saros Z70 include 22,000Pa of suction power, a dual anti-tangle system for the roller brushes, a dual mop that can be raised 2.2cm to avoid carpets and automatically detach at the charging dock when not needed. At less than 8cm tall, the Saros Z70 can easily move under low sofas and features the AdaptLift chassis first seen on the Qrevo Curv, helping the robot overcome high edges and move on thick carpets.

The robot is connected to Roborock's new Multi-Purpose Dock 4.0, which supports charging, automatic dust collection, filling and draining, hot water mop washing, and hot air drying. This model also supports 2.5-hour fast charging.

While the robotic arm is the highlight, the Saros Z70 is clearly an experimental product (though Roborock says it will ship this year). So in addition to the Saros Z70, Roborock is also unveiling two other high-end robot vacuums at CES: the Saros 10R and Saros 10, which will hit shelves on February 10 for $1,599.99 each. Both feature the same slimline design and AdaptLift chassis as the Z70 and can automatically detach the mop when not needed.

The main difference between the two models lies in the cleaning and navigation technology. The Saros 10R has the same StarSight 2.0 obstacle detection and navigation technology, cleaning technology, and docking station as the Z70, but has slightly less suction power (19,000Pa).

Meanwhile, the Saros 10 is an upgrade to Roborock’s current flagship model, the S8 MaxV Ultra (our top pick for best robot vacuum). With 22,000Pa of suction, the Saros 10 uses the familiar lidar navigation system found on most Roborock machines but can retract the lidar tower to move in low spaces, bringing the machine’s height to the same level as the other two Saros models.

Instead of the oscillating mop found on the Z70 and 10R, the Saros 10 features a new version of Roborock's signature VibraRise mopping feature. This uses a flat mop pad that vibrates 4,000 times per minute to simulate a scrubbing action and can now moisten dry stains before removing them.

The Saros 10 also comes with Roborock's improved Reactive AI Obstacle Avoidance 3.0, VertiBeam cable avoidance technology, the DuoDivide anti-tangle roller brush first seen on the Qrevo Curv, and paired with the new Ultra 2.0 Dock.

Roborock says all three new models will be updated to support Matter 1.4, allowing them to work with any smart home platform that supports Matter. Out of the box, the robots will be compatible with Alexa, Siri Shortcuts, Google Home, and Roborock's Hey Rocky voice assistant.
