Roborock Saros Z70 Review: The Future of Robot Vacuums with OmniGrip Robotic Arm

Today, we’re taking an in-depth look at the Roborock Saros Z70. Big thanks to Roborock for sending us this unit—though, as always, all opinions are our own. If you’re interested in picking one up, you’ll find a purchase link in the description below.

We first got hands-on with the Z70 back in April at an exclusive Roborock event in New York City, ahead of its official launch. This was our first experience with the OmniGrip robotic arm, which is designed to pick up small items like socks, towels, and slippers and place them into designated storage zones. That early demonstration gave us a real appreciation for how far Roborock is pushing smart home robotics, and we’ve been eagerly waiting to test the Z70 more thoroughly in our studio.

Unboxing and Setup

We received the silver model of the Z70, although it’s also available in black. Inside the box, you’ll find the vacuum itself, a multi-purpose station, a station ramp, a gray power cord, an extra dust bag with one pre-installed, a designated storage bin, two magnetic mop pads, and a variety of product literature, including a comprehensive quick start guide.

Setup is straightforward. Simply snap the station ramp and mop pads into place, plug in the unit, let it charge, and fill the clean water and solution tanks. Once that’s done, the Z70 is ready for its first run.

Cleaning Performance

During our initial cleaning run, the Z70 handled a busy household with ease. In a home with three people with long hair and a long-haired dog, it picked up hair, crumbs, dirt, and fine dust with impressive efficiency. One of the first things we noticed was the roller brush. Unlike the Saros 10 and 10R, which use the Duo Divide rollers, the Z70 features a hair-cutting brush. While the Duo Divide remains our preferred design for preventing hair tangles, the Z70’s brush still performed well, leaving only a few stray fibers that would likely be trimmed during the next cycle. We’re curious why Roborock opted to leave the Duo Divide off this model and hope it returns in future versions.

The OmniGrip Robotic Arm

The true standout of the Z70 is the OmniGrip robotic arm. At launch, it can automatically recognize and pick up five types of items: socks, small towels, tissue paper, and sandals or slippers weighing under 300 grams. For other objects, users can switch to manual pickup mode through the Roborock app, which provides a live camera feed and joystick-style controls for precise operation.

The app also allows users to set up dedicated storage zones, such as the included storage box or a designated shoe area, so the robot knows exactly where to place collected items. The Z70 supports two handling modes. In automatic sorting, it picks up recognized items during cleaning and deposits them in the proper storage zones. Slippers and shoes are sorted after cleaning. In manual sorting, users can review flagged items post-cleaning and decide what gets sorted. There’s even a follow-up cleaning mode, where lightweight objects like socks, shoes, or paper balls are moved out of the way so the Z70 can clean underneath.

Using the robotic arm has been a lot of fun, and while its current capabilities are limited, it represents an exciting step forward in smart home robotics. We’d love to see future updates include more granular control, the ability to assign specific zones for individual items, and perhaps the option to train the system to recognize custom objects like toys, pet items, or personal shoes. Optional accessories like magnets, hooks, or scoops could expand its functionality even further. Roborock has already announced that this summer the Z70 will gain improved support for sports shoes, smarter item sorting, and better object placement, along with enhancements to navigation and obstacle recognition.

Limitations

Roborock has been transparent about the Z70’s current limitations. The robot cannot pick up socks from carpet, struggles to cross thresholds while carrying items, and has difficulty with very small, flat, shiny, or dark-colored objects due to sensor constraints. The robotic arm moves deliberately slowly by design, and while it is rated for a 300-gram load, in practice it can handle up to 700 grams.

Suction and Overall Cleaning Performance

When it comes to traditional vacuuming, the Z70 is undeniably flagship-class. Its suction is rated at 22,000 Pascals—the highest we’ve seen from Roborock—and airflow reached 8.2 CFM, beating the Saros 10 and 10R. In real-world testing, it outperformed the average by over 40 feet per minute, and its carpet deep-cleaning performance was near perfect, scoring 95 out of 100. Despite its power, it runs only slightly louder than average, a difference most users would barely notice.

Another standout feature is the ability to fully detach mop pads at the dock when cleaning carpets, a rare and highly effective feature for protecting soft flooring. The trade-off is a smaller onboard dust bin, which is necessary to make space for the robotic arm. With the self-mopping system, this isn’t a dealbreaker, though it does mean more frequent trips to the dock.

The Multi-Functional Dock

The Z70’s dock is one of the most capable we’ve seen. It handles self-mopping, mop washing and drying, solution dispensing, and even full station cleaning. The water heats to high temperatures, and drying performance is above average. One minor drawback is that cleaning solution is not included in the box.

Roborock App

The Roborock app, available on both iOS and Android, is powerful, intuitive, and feature-rich. Users can choose between whole-room, room-specific, zone, or scheduled cleanings, and fine-tune suction, scrubbing intensity, water flow, and path behavior. The app supports multiple mapping, customizable no-go zones, and full control of the dock, including manual triggering of dust emptying, mop washing, and drying cycles.

Smart assistant support includes Amazon Alexa, Apple HomeKit, Google Assistant, and Roborock’s own Hello Rocky. Security-conscious users can enable remote patrol mode and live viewing. Notably, the robotic arm has its own built-in camera, providing a unique view of your home and enabling full manual control for object pickup. Additional features include Matter support, off-peak charging, and a dedicated deep carpet cleaning mode.

User reviews reflect its quality, with averages of 4.6 stars on Android and 4.8 on iOS. Users praise its sleek design, quiet operation, ability to fit under low-profile furniture, and the robotic arm’s functionality. On the downside, some mention the high price, limited arm functionality at launch, and questions about long-term durability due to the additional moving parts.

Final Thoughts

The Roborock Saros Z70 is not just a robot vacuum—it’s a bold step toward a smarter, more interactive home. While there are early limitations, the OmniGrip robotic arm represents a major leap forward, combining flagship-level cleaning performance with future-facing technology. Between its powerful suction, advanced features, and highly capable dock, the Z70 delivers a glimpse of what next-generation home robotics can achieve.

Yes, it comes at a premium, but for those willing to invest in cutting-edge smart home tech, it offers an exciting look at the future of intelligent home assistance. If Roborock continues on this trajectory, we may soon be talking about robots that do much more than just clean our floors—they could become true household assistants.
