Roborock SAROS Z70

1 What Agent AI Makes Possible

The Z70’s Agent Artificial Intelligence allows it to do something most robots simply can’t: when it encounters an object like a sock or a toy, it doesn’t just go around it or get stuck. It identifies it, grabs it, and moves it out of the way to continue cleaning.

This different approach to obstacles is what largely justifies its higher price compared to models like the Dreame X50 or the Saros 10R.

2 Lower Profile, More Areas Cleaned

Many modern pieces of furniture have very little space underneath. Taller robots with LiDAR turrets simply can’t fit, leaving those areas uncleaned.

With a height of just 7.98 cm, the Roborock Saros Z70 can easily pass under sofas, beds, and low furniture. By removing the top-mounted LiDAR, it reaches places other robots simply can’t.

3 AdaptiLift™: Adapts to Your Floors

The Z70 isn’t just low-profile—it can also lift itself when needed. Thanks to the AdaptiLift™ system, the robot can automatically raise or lower its chassis instead of relying solely on its wheels.

This allows it to overcome thresholds and height differences of up to 4 cm, which is crucial in homes with high door frames or uneven flooring. It also adjusts its height on carpets, improving suction and preventing unnecessary battery drain.

4 More Precise 3D Navigation

Replacing traditional LiDAR with the StarSight™ Autonomous System 2.0 marks a major shift in how the Z70 navigates.

Instead of relying on simple cameras or LiDAR that “sees” in a single plane, StarSight uses 3D Time-of-Flight (ToF) technology. This allows it to understand depth and recognize surrounding objects more accurately.

5 Works Well Even in Low Light

A common concern with these systems is how they perform in low-light environments. Unlike traditional LiDAR, StarSight 2.0 doesn’t rely solely on ambient light.

To compensate, it uses infrared light and supporting systems that allow it to move under furniture or in dark areas. In testing, navigation performance is solid and consistent in most situations.

However, some users report that in unusual or challenging lighting conditions, it can become slightly more disoriented than turret-based LiDAR models. Still, in everyday use, it performs without major issues.

6 Object Recognition with Smart Reactions

The Roborock Z70’s navigation system can identify up to 108 different types of objects. This is key for determining the right action in each situation. A table leg, pet waste, and a sock all require different responses.

Thanks to this recognition, the robot decides whether to avoid the obstacle, go around it, or activate its mechanical arm to move it. Through the app, users can also teach it up to 50 custom objects, allowing the robot to better adapt to each home and improve over time.

7 The OmniGrip™ Mechanical Arm

The biggest differentiator of the Roborock Z70 is the OmniGrip™ mechanical arm. This feature completely changes the robot’s role: it doesn’t just clean—it can interact with objects in its environment.

The arm has five axes of movement, allowing it to extend, rotate, and grab objects. When not in use, it folds entirely into the chassis without affecting cleaning performance or design. It’s designed to move lightweight objects of up to 300 grams, such as socks, small toys, loose cables, or paper.

In practice, its performance is mixed. In controlled tests it works well, but in real-world use, the success rate is around 50% for certain objects. Shape plays a major role: very flat or smooth items are harder for the gripper to handle. Still, it’s an innovative concept that clearly sets it apart from other robot vacuums.

8 Cleaning Performance: Power That Needs Context

The Z70 advertises a suction power of 22,000 Pa, an extremely high figure even compared to previous flagship models like the S8 MaxV Ultra, which offers 10,000 Pa. On paper, the jump is huge.

However, more power doesn’t always translate into proportionally better cleaning. Beyond a certain point, what really matters is brush design, airflow, and how effectively dirt is agitated.

On carpets, for example, tests show that despite its raw power, the Z70 can perform below the Saros 10R in deep dirt extraction, especially fine sand. This is mainly due to the cleaning head design, not a lack of suction.

9 Active Hair Cutting: Less Maintenance

A major advantage of the Roborock Saros Z70 is the active hair-cutting system integrated into the brush. This mechanism cuts long hair while cleaning, preventing it from tangling around the roller.

This significantly reduces manual brush cleaning and helps maintain consistent performance. It’s also present in the 10R and is essential for truly autonomous cleaning, especially in homes with pets or long hair.

10 More Effective and Complete Mopping

Unlike the S8 series, which used the VibraRise vibrating plate system, the Z70—like the rest of the Saros lineup—uses a dual rotating mop system. In practice, this change improves mopping performance, especially on dried stains, thanks to constant friction.

The Z70 also features the FlexiArm Mop, an extendable mop inherited and improved from previous models, which deploys to clean edges and corners. This allows better coverage and reduces areas that used to remain uncleaned.

11 Base Station 4.0: Everything Cleans Itself

The Z70 relies heavily on its base station, which is why this point is crucial. The base doesn’t just recharge the robot—it handles almost all maintenance tasks.

One of the most important upgrades is mop washing with 80 °C water. At this temperature, it removes not only visible dirt but also bacteria and odors. Hot water is especially useful in kitchens, where grease and oil residues require high heat to be properly cleaned.

The station also cleans itself. It uses hot water and internal brushes to keep the washing tray clean, preventing residue buildup—a common issue with many automatic bases. Finally, it includes a detergent tank with automatic dosing, so there’s no need for manual mixing.
