Roborock Saros Z70: Complete review of the robot vacuum cleaner with mechanical arm

Roborock Saros Z70

A robot that vacuums... and tidies up?


Just when you thought you'd seen it all in the world of robot vacuums, Roborock pulls out a model that doesn't just avoid obstacles, but actually starts moving them . Yes, you read that right.


The Roborock Saros Z70 features a mechanical arm called OmniGrip , which can pick up certain objects on the floor. Got a sock lying around? The robot can drop it in a sorting box. And between jobs, it vacuums and mops like a pro, with its 22,000 Pa , rotating pads, and 5-in-1 dock .


So, is this just a marketing gimmick or a true revolution? To answer this question, we tested the Roborock Saros Z70 in real-life conditions, including children's toys and cat hair. Spoiler: this robot isn't perfect, but it's got what it takes... and what it can do.


A robotic arm on the Roborock Saros Z70 : useful or gimmick?


How the OmniGrip Arm Works


The OmniGrip mechanical arm deploys on command or automatically to grip certain light objects (up to 300 g) such as:

  • socks,

  • papers,

  • sandals,

  • towels,

  • slippers.


Once entered, objects can be moved to:

  • a defined storage area ,

  • a sorting box supplied with the robot.


Intelligent recognition and limits


The robot uses its onboard camera and an AI algorithm to identify objects. Each detection is displayed in the app with:

  • object type,

  • photo,

  • precise position.


Unfortunately , only a few types are recognized so far. And despite the precision of the gestures, handling remains slow.


Powerful suction at 22,000 Pa: a competitive vacuum cleaner


Suction test on various floors


The Roborock Saros Z70 reaches 22,000 Pa , one of the best suction levels on the market.


Our observations:

  • on tiles: 1 pass is enough,

  • on carpet: automatic power increase,

  • on thick carpet: a little less efficient (lack of double roller).


Main brush and side brush


  • FreeFlow central brush : limits blockages,

  • FlexiArm side brush : good edge coverage,

  • Suitable for pet hair… but not perfect.


A uniform wash without vibrations


Extendable rotating skates

  • 2 rotating mops,

  • one extendable to reach the baseboards,

  • Effective washing on fresh stains (marks, splashes).


Results on stubborn stains

  • Dried coffee: 2 passes,

  • Fat or sauces: 3 passes required,

  • Automatic rewash mode could be improved.


Multifunction station and automated maintenance


Station Features

  • Automatic dust emptying,

  • Wash at 80°C,

  • Drying at 55°C,

  • Water filling,

  • Detergent distribution.


Ease of maintenance

  • Low maintenance required,

  • Slightly bulky station,

  • Removable washboard.


StarSight 2.0 Navigation and Obstacle Recognition


Navigation equipment

  • ToF sensors,

  • Front camera,

  • Integrated LiDAR,

  • LED for night vision.


Performance in real-life situations

  • Accurate and fast mapping,

  • Good threshold management (up to 4 cm),

  • Some recognition errors on cables or lint.


Roborock App: Full control over the robot vacuum cleaner


Key features of the app

  • Manual control of the OmniGrip arm,

  • Management of cards by floor,

  • Personalized scenarios,

  • Live onboard camera,

  • Prohibited areas, detailed programming.


Home automation compatibility

  • Matter ,

  • Google Assistant ,

  • Amazon Alexa ,

  • Siri / HomeKit (via gateway).



❓ FAQ: 5 Frequently Asked Questions About the Roborock Saros Z70


1. Is the OmniGrip arm really useful?

Above all, it's impressive! It can pick up some objects, but it's slow and limited to a few categories. It's useful, but not yet essential.


2. What is the difference with the Roborock Saros 10 ?

The Saros 10 focuses on pure power. The Z70 adds interaction with its robotic arm. It's more home automation than household cleaning.


3. Does the robot go under furniture?

Yes! At only 7.98 cm high , it is one of the flattest on the market.


4. Is it noisy?

No. It remains discreet around 58-60 dB , and the station does not exceed 65 dB .


5. Can the arm be controlled remotely?

Yes, via the app. A virtual joystick allows you to manually aim, grab, and drop objects.


✅ Conclusion: The Roborock Saros Z70 opens a new era of connected cleaning


The Roborock Saros Z70 isn't just a great robot vacuum and mop. It's a technological showcase , with a slightly crazy idea that has become reality: a robot that vacuums AND cleans .


The OmniGrip arm is impressive, even if it remains limited. The suction is powerful, the cleaning is consistent, the navigation is controlled, and the dock is incredibly efficient.


So yes, it's expensive. Yes, some features could still be improved. But if you're a techie and want a high-end robot vacuum that's a step ahead of the future of home automation, this is definitely the model to follow.


For those who prefer a more classic but equally effective model, take a look at the Roborock Saros 10R or the Dreame X50 . But what if you want your robot to pick up your dirty sock? You know what to do.
