2. What Makes It Viral

The Roborock Saros Z70 didn’t just quietly slip onto store shelves. It exploded onto the internet and generated massive buzz from the moment it was shown at CES 2025. And for good reason — it does something no other mass-produced robot vacuum has ever done before: it picks up objects off your floor and moves them to where they belong.

Think about how many times you’ve had to manually pick up a sock, a shoe, or a crumpled tissue before running your robot vacuum. With the Saros Z70, that pre-cleaning ritual is becoming a thing of the past.

During its first cleaning session, the Saros Z70 detects and marks objects it can lift, then circles back to clean missed areas in the second session. This two-pass intelligent system means your floors get genuinely cleaner — not just the parts that were already clear.

The “robot vacuum picks up objects” concept is what most people can’t stop sharing on social media. Videos of the Saros Z70 scooping up socks and depositing them near a closet have racked up millions of views across platforms. It taps into something deeply satisfying — the idea that your robot isn’t just cleaning around your mess, it’s actually dealing with it.

The Roborock Saros Z70 earned the Most Innovative Robot Vacuum Award for Mid-2025 thanks to its groundbreaking OmniGrip mechanical arm — the first of its kind to autonomously stow small objects into a user-defined compartment — alongside industry-leading mopping performance, near-flawless 3D Time-of-Flight obstacle avoidance, and a multifunction dock that washes, dries, and dispenses detergent for its mop pads.

This is what a next generation robot vacuum looks like. It doesn’t just react to your home — it interacts with it.

3. OmniGrip Technology Explained

At the heart of the Saros Z70’s wow factor is the OmniGrip arm. Let’s break down exactly what it is and how it works, because it’s genuinely impressive engineering.

At the core of OmniGrip is a system combining pressure sensors and computer vision. The robotic arm uses an RGB camera to visually identify objects and assess their size, shape, and position. Pressure sensors ensure the grip strength is appropriate, avoiding damage to objects. The LED light aids the arm’s operation by providing consistent illumination, which helps the Saros Z70 recognize objects even in dimly lit environments.

The five-axis design means the arm can move in multiple directions — not just up and down, but with nuanced rotational movement that allows it to approach objects from different angles. The five-axis foldable arm can move both horizontally and vertically and is able to handle objects weighing up to 300 grams.

What makes this a true robotic vacuum with manipulator technology — and not just a gimmick — is the folding mechanism. When the arm isn’t in use, it folds compactly inside the robot’s chassis, occupying minimal space. Based on internal measurements conducted by the manufacturer, the mechanical arm occupies just 10% of the total product space of the Saros Z70. This is a remarkable feat of engineering, especially given the robot’s ultra-slim 7.98 cm profile.

Safety was clearly a priority in the design of the OmniGrip system. The Saros Z70 is designed with multiple safety protection devices and mechanisms to prevent the moving robotic arm from injuring users, children, and pets. These include a robotic arm switch to disable it when not needed, an emergency stop button, pressure switch and anti-pinch sensors, collision sensing, and grip force restrictions.

Currently, the arm is programmed to handle a defined set of household items. Recognizable and organizable objects include socks, sandals, crumpled tissues, and towels under 300g, with new items being added continually via firmware OTA updates. This means the RoboSwing robot vacuum concept — a robot that actively manages your home’s clutter — will only get smarter over time.

4. AI Capabilities and Smart Navigation

The Saros Z70 is a robot vacuum with AI arm, but the intelligence doesn’t stop there. The entire machine is packed with AI-powered systems that work together to make your home cleaner with less effort from you.

The Saros Z70 features the advanced StarSight Autonomous System 2.0, providing smart navigation and obstacle avoidance. Its VertiBeam Lateral Obstacle Avoidance technology enables the robot to accurately detect and navigate around obstacles like furniture legs, cables, and up to 108 other types of obstacles. This ensures precise movement in complex layouts, delivering thorough and reliable cleaning coverage even in challenging environments.

The StarSight 2.0 system is a major upgrade over previous generations. It creates detailed spatial awareness with more than 21,600 data points at a frequency of 38,400 Hz — building an incredibly precise real-time picture of your home’s layout.

What’s exciting about the Saros Z70 as a smart robot vacuum with obstacle removal is the custom AI training capability. Beyond its pre-programmed 108 object recognition, the Z70 allows users to define and label up to 50 new objects in the Roborock app for a fully personalized experience. AI-driven recognition features are delivered through OTA updates.

Using precision sensors, a camera, and an LED light, the OmniGrip arm is able to determine its position, surroundings, and the weight of each object it grips. This ensures the mechanical arm operates with exceptional accuracy. The built-in sensors prevent it from lifting items over a safe threshold.

The dual camera system adds another layer of intelligence. The Saros Z70 is designed with dual cameras: one on the mechanical arm and one at the front of the vacuum. This design enhances accuracy when gripping objects and provides the convenience of camera switching, allowing you to get a higher view of your home environment.

There’s also a built-in voice assistant. The Saros Z70 features a built-in intelligent voice assistant called “Hello Rocky,” allowing you to start cleaning tasks without the need for a network connection. It’s a small but genuinely convenient feature that rounds out the device’s smart home credentials.

5. Real-Life Use Cases

Specs and technology are one thing, but how does the Roborock Saros Z70 actually perform in everyday life? Here’s where things get really interesting — and where honest expectations also matter.

Scenario 1: Morning Floor Cleanup. You wake up, the living room floor has a few socks, a crumpled napkin, and a pair of slides near the couch. In the past, you’d have to clear these before running your robot. Now, you simply tell the Saros Z70 to start its run. It identifies the items during its first pass, picks them up, deposits them in designated locations — the sock goes toward the closet, the tissue toward the trash box — and then finishes cleaning the now-clear floor.

Scenario 2: Pet Owner’s Paradise. The Pet and Pet Area Recognition feature pauses the main brush and moves aside to avoid frightening pets, while boosting suction around pet areas for a thorough clean. The robot also captures Pet Snaps so you can download and cherish snapshots of your pets during cleanups. You can even activate the Search for the Pet function to roam your home and help find a hiding animal.

Scenario 3: Video Call from Anywhere. The dual camera system isn’t just for cleaning navigation. The Saros Z70 features Video Call and Cruise functionality to check on pets, schedule on-demand cruises, or manually control patrols with just a tap.

Scenario 4: Multi-Floor Homes. The robot supports customizable multi-floor mapping, so it knows how to behave on different levels of your home — bedroom versus kitchen, tile versus thick carpet.

The robot vacuum picks up objects capability is genuinely useful for everyday items. It’s worth noting that the feature is still maturing, and real-world performance can vary. Independent testing found that success rates were hit-or-miss at times — sometimes the robot picks up objects and places them correctly, sometimes it doesn’t. The feature is well-suited for early adopters and those interested in trying new things. The good news is that every OTA update makes it smarter.

6. Design and Build Quality

The Roborock Saros Z70 features a design philosophy that balances innovation with practicality in ways that are immediately apparent when you look at the device.

The first thing you notice is how thin it is. Key features include the 7.98 cm ultra-slim design, StarSight Autonomous System 2.0, Dual Anti-Tangle System, 22,000 Pa HyperForce suction, industry-first AdaptiLift Chassis, and FlexiArm Riser Technology.

That 7.98 cm (3.14 inch) height means the Saros Z70 can slide under most sofas, beds, and low-clearance furniture — the places where dust and debris love to accumulate. This is especially impressive given that the robot is also hiding a five-axis mechanical arm inside its chassis.

The AdaptiLift chassis ensures the mop pads are well above carpeted areas to prevent accidental wetting, and it can traverse thresholds up to 4 cm high. This means transitioning between different floor types — hardwood to tile to area rugs — is handled seamlessly and automatically.

The dock is equally well-designed. The 10-in-1 Dock 4.0 provides full self-service emptying and refilling of its dustbin and water tanks, along with detergent dispensing, mop washing, drying, and more. Hot water mop washing reaches 176°F, as does the hot water dock self-cleaning cycle — both ensuring hygienic, hands-free maintenance.

The overall aesthetic is sleek and modern — the kind of device you don’t mind leaving in full view in your living room. It looks like a premium product, because it is one.

8. Comparison with Traditional Robot Vacuums

To truly appreciate the next generation robot vacuum category that the Roborock Saros Z70 represents, it helps to compare it against what came before.

Traditional robot vacuums — even good ones — operate on a simple principle: navigate around obstacles, vacuum what’s accessible, and return to dock. The user’s job is to prep the floor before each run, clearing socks, cables, small toys, and other items that would either stop the robot cold or get sucked up accidentally.

The Saros Z70 flips that model on its head. Rather than working around your mess, it engages with it.

 

Feature	Traditional Robot Vacuum	Roborock Saros Z70
Object Handling	Avoids or gets stuck	Picks up and relocates items
Pre-cleaning Required	Usually yes	Largely eliminated
Obstacle Recognition	Basic (bump-and-go or simple AI)	108 types + 50 custom via app
Navigation	LDS or basic camera	StarSight 2.0 with 3D ToF + 21,600 data points
Mopping	Basic damp pad	Hot water spinning mops, 176°F wash
Home Interaction	None	Video call, pet search, voice assistant
Dock Intelligence	Simple charging only	10-in-1 fully autonomous maintenance dock
Slim Profile	Typically 9–11 cm	7.98 cm industry-leading slim design

 

The gap between what a traditional robot vacuum can do and what the Saros Z70 offers is enormous. It’s not just a better vacuum — it’s a genuinely different category of home robot.
