I’ve spent years transforming my home into a modern smart house, and while many futuristic predictions have come true, one major piece has been missing: a true household robot assistant. That gap is finally starting to close.

Groundbreaking Robot Vacuum Technology Now More Affordable
The Roborock Saros Z70, originally priced at $2,599, is currently available for $1,999 – a substantial $500 savings. This isn’t just another robot vacuum; it’s the first commercially available robot vacuum with a mechanical arm designed to lift lightweight objects and clean previously inaccessible areas.
After extensive testing of this innovative device, I can confidently say that Roborock has established a significant advantage in the household robotics market. While the technology isn’t perfect, it represents a genuine stepping stone toward the smart homes of tomorrow.
How the OmniGrip Mechanical Arm Works
The standout feature of the Saros Z70 is undoubtedly its OmniGrip mechanical arm. During cleaning cycles, the robot detects small obstacles it can handle, picks them up, navigates to a predetermined drop-off location, and then returns to clean the previously occupied space.
The device comes with a dedicated Roborock bin that resembles a small trash can. After the robot maps your home, you place the bin and designate its location in the mobile app. You can also create larger drop-off zones for items like slippers and lightweight shoes.
Real-World Performance Testing
The critical question: Does it actually work? After conducting multiple tests with varying numbers of obstacles, I’m pleased to report that it does – most of the time.
In my testing, the mechanical arm successfully picked up intended objects 83% of the time overall. This is impressive for groundbreaking technology. When limited to officially recognized objects – currently socks, sandals, crumpled tissues, and towels under 300g (8 ounces) – the success rate jumped to 90%.
Roborock has committed to continuously expanding the list of recognizable objects through firmware updates, which should improve performance over time.
Exceptional Vacuum and Mop Performance
Beyond the mechanical arm innovation, the Saros Z70 excels as a traditional robot vacuum and mop. It features:
- Outstanding obstacle avoidance – the best I’ve encountered
- Extendable mop pad for edge cleaning
- Thorough cleaning coverage reaching nearly every inch of floor space
- Reliable navigation that prevents getting stuck
Minor Bugs and Limitations
I did encounter some issues, though they’re understandable given the novelty of this technology:
- Occasionally “forgetting” to resume mopping after dropping off objects
- Difficulty gripping certain items like children’s water shoes
- Limited initial object recognition list
These bugs are relatively minor and expected for first-generation technology of this type.
Who Should Buy the Roborock Saros Z70?
The Saros Z70 isn’t for everyone. This robot vacuum is ideal for early adopters who enjoy testing cutting-edge technology and don’t mind occasional bugs. As the first widely available robot vacuum with a mechanical arm, you’re paying for innovation as much as functionality.
However, it is quite expensive even with the discount. You’re not just purchasing a robot vacuum – you’re investing in a multipurpose household robot that represents the future of home automation.
For those willing to embrace new technology and accept its growing pains, the Roborock Saros Z70 offers a genuine glimpse into the future of smart home cleaning. The combination of excellent vacuuming and mopping performance with pioneering mechanical arm technology makes it a compelling option for tech enthusiasts.
With the current $500 discount bringing the price to $1,999, now may be the perfect time for early adopters to experience this groundbreaking technology firsthand.
