Roborock’s latest robot vacuum grew a robotic arm, and it’s changing what a cleaning robot can do. First announced at CES 2025, The Saros Z70 is the first of its kind to feature a mechanical arm capable of picking up household items like socks and small toys.
It also packs 22,000Pa of suction, spinning and articulating mops, hot water mop washing, fast charging, and Roborock’s slimmest low-profile design. The Roborock Z70, along with Roborock’s app, is jam-packed with features and abilities that make it the most advanced and ambitious robot cleaner to date.
Saros Z70 Explained
It’s the retractable robotic arm that earned the Z70 all the awards at CES, and it’s the feature that instantly sets this model apart from anything else on the market.
Beyond the robotic arm, the Z70 stands as Roborock’s most advanced robot vacuum and mop to date. It boasts an impressive 22,000Pa suction power, dual spinning mops that automatically lift on carpets, and a low-profile design measuring just 3.14 inches in height, allowing it to clean under most furniture.
The Multifunctional Dock 4.0 enhances the hands-free experience with features like 80°C (176°F) hot water mop washing, 55°C (131°F) warm air drying, auto mop removal, auto detergent dispensing, and a 2.5-hour fast charging capability.
Navigation is handled by Roborock’s latest StarSight 2.0 system, which replaces the traditional top-mounted LiDAR turret with a front-facing sensor array. This design choice contributes to the vacuum’s sleek profile and enables it to navigate complex environments effectively.
This advanced device pairs with one of the best vacuum apps out there, making its deep feature set feel approachable and intuitive. It supports voice control via Alexa, Siri, and Google, plus it has Matter support for broader smart home compatibility.
There’s an onboard voice assistant, Rocky, that can handle basic commands without needing another device. The vacuum has a built-in camera that can be used for remote viewing, remote controlling, and even to find and take pictures of pets or obstacles.
While it’s easily the most advanced and feature-rich vacuum in Roborock’s lineup, there’s only a few shortcomings, the most notable being its price. It doesn’t use Roborock’s latest dual-roller system intended to increase performance and reduce tangles, but it does have built-in blades to cut hair. It also comes with a smaller onboard water tank and dust bin, which technically means more frequent trips back to the dock, reducing battery.
The Robot Arm
The claw is really something. Roborock calls it the OmniGrip arm, and it’s a first of its kind. It’s a 5-axis robotic arm with a surprisingly powerful gripper that can lift objects up to 300 grams. In practice, that means it can move socks, cables, kids’ toys, small towels or clothing, and even a men’s size 13 sneaker—though it can be hit or miss.
What’s impressive is how seamlessly and covertly the arm folds into the design. The Z70 is actually one of the thinnest vacuums Roborock makes. Aside from a slightly smaller onboard water tank and dustbin, there aren’t many trade-offs to make room for the arm.
When the claw grips something, it does so with serious strength. There were a couple of times I had to pry an object loose and it took more effort than expected. There’s a kill switch that works while the claw is in action, but it doesn’t work after the claw gets stuck. I did find a claw release in-app.
The arm isn’t just for removing clutter, either. It can temporarily shift objects out of the way to clean under them. It relies entirely on the Z70’s front-facing camera and AI object recognition to decide what to pick up and what to avoid. That makes it smart, but not perfect. In my testing, I’d give it about a 75% success rate.
Often times it avoids lightweight things it could handle, and other times it’ll try (and fail) to pick up something that’s awkwardly shaped or positioned. The experience has been a bit unpredictable, but it does mostly work. In theory it should get better with software updates too.
By default, the arm is turned off in the settings. Once enabled, you can assign pickup zones and even designate a spot for shoes. Roborock includes a little bin that the vacuum will use as a drop-off point. Watching it in action is kind of mesmerizing. It can take a few minutes to navigate and drop something off, depending on how far away the basket is.
There’s also something strangely satisfying about coming home to find socks or toys sitting neatly in the bin like the vacuum tidied up after you. In some cases, we’ll come home to find our stuff scattered outside the bin, but having it all in one place is still good.
We’ve noticed this vacuum actually gets stuck less, not more, with inclusion of the robotic arm. Perhaps improved cameras and object recognition allows it to avoid more problematic obstacles.
Cleaning and Experience
The Z70 really seems to be the best of all worlds. As both a vacuum and a mop, it delivers possibly the best performance on the market with the polish and reliability you’d expect from a Roborock flagship.
It handles daily dirt with ease, and the results speak for themselves: clean floors, minimal babysitting, and fewer interruptions than we’ve had with any previous model (even with some claw issues). The AI smart features help ensure a great clean without having to think about configuration settings.
Navigation and floor handling are excellent. The Z70 climbs thick gym mats and transitions between surfaces without hesitation, which many premium vacuums still struggle with. It can even set its own no-go zones based on areas it thinks it will get stuck. It’s also noticeably quieter than most robot vacuums. It’s tolerable to be in the same room while it runs, though, like most vacuums, it’s still not exactly soothing background noise.
My Z70 runs for a little over 2 hours with mopping and the robotic arm enabled. This cleans most of my floorplan, and the 2.5 hour fast charge means that it will be finished thoroughly cleaning my home before the end of the work day.
Overall vacuum performance has been on par with our other Roborock flagship, the Q Revo Curv, which had already set a high bar. You can tell it’s doing its job by how little dirt accumulates between cleans—it stays on top of things.
The mopping, while not a total replacement for manual scrubbing, works as well or better than any robot mop we’ve used. It can’t always tackle stuck-on kitchen grime, but it leaves floors looking polished and generally does a good job in high-traffic areas like the kitchen and entryways. Corner and edge cleaning is particularly strong on this vacuum. The precision navigating with the LiDaR combined with the articulating side brush and mop arm makes a real difference in hard-to-reach areas.
One of our favorite features is that the scheduled cleaning will go on as planned even if the dock runs out of mop water. Other vacuums will abort the job. This makes it easier and less urgent to replace the mop water every 2 or 3 days. The mop and all the maintenance has been easy to manage, especially with the app prompting us to do everything. It’s no more than ten minutes per week, if even that.
Hair pickup has been great so far. While the Z70 doesn’t use the dual-roller brush found on some other models, we haven’t run into any major tangles yet. Roborock’s “active cutting technology” seems to be doing its job by cutting hair off the main bush.
The app is still the best we’ve used. Scheduling, mapping, and customization are intuitive and powerful without being overwhelming. Most of the default settings are some form of smart, AI, or balanced and they work very well. The setup is painless, and it’s really easy to fine-tune things when you want to get more customized. The one thing you’ll definitely want to configure is the robotic arm.
We find it more reliable to use the smart home integration with iOS and Google instead of the built-in assistant, “Rocky”. The built-in camera may not be essential, but it’s handy when you need it for checking in on pets or just confirming it’s doing its job. One nice feature of the camera is that it can take pictures to show you obstacles it runs into.
More than anything, the Z70 has been dependable. It hasn’t needed much babysitting, and it only gets stuck or confused once or twice a week. That kind of reliability makes a big difference.
Final Thoughts
Roborock continues to lead the pack when it comes to pushing the boundaries of home cleaning, and the Saros Z70 is a clear example of that. The robotic arm is a glimpse into the future—it’s smart, surprisingly useful, and adds a layer of intelligence we’ve never seen in a vacuum before. Combined with excellent vacuuming, solid mopping, and best-in-class software, this is easily one of the most complete robot cleaners we’ve tested.
That said, it comes at a steep price and the robotic arm isn’t as polished or reliable as it could be, but we expect that it will keep getting better with software updates. That said, while we admire Roborock’s ambition, this first-gen product feels like it’s best suited for early adopters.
If you’re curious and can afford the premium, the Z70 delivers on most of its promises. But for the more practical buyer, it’s worth watching how this line (and pricing) evolves. The Roborock Saros Z70 Robot Vacuum with OmniGrip Mechanical Arm is currently selling for $2,599.
