UPDATE: Sep. 4, 2025, 6:30 p.m. EDT This post was originally written in January 2025 and has been updated to reflect current pricing information for the Roborock Saros Z70, Saros 10, and Saros 10R. Each model has also since been tested at home, with my experiences documented below.

It’s unlikely that many people had a robot vacuum with a whole-ass arm on their CES 2025 bingo card. But alas, Roborock gave us one: the Roborock Saros Z70, which costs $2,599 regularly. That’s steep but expected, considering the current high-end Roborocks with no robotic limbs go for over $1,500-ish (a few hundred less if they’re on sale).
Where can you buy the Roborock Saros Z70?
If you’re in the market for a new robot vacuum — and are open to buying one on the more expensive end of the spectrum — you still have plenty of time to decide whether the arm thing is overkill even for you. The Roborock Saros Z70 began shipping in April 2025, and is currently available for purchase at Amazon, Best Buy, and Roborock’s website. Roborock’s site is the only place that has sported the Saros Z70’s first big discount: It was $1,000 off for a few days in August and September.
What’s so special about the Roborock Saros Z70?
The Roborock Z70 goes past the small obstacle avoidance technology that has become a navigational staple in the best robot vacuums, instead, bulldozing into obstacle removal technology. It performs such with a robotic OmniGrip arm that unfolds out of the top of the robot vacuum to grab the obstacle claw machine-style, and drops it in a nearby designated area. The live demo at CES 2025 showcased the Z70 putting socks into a basket.

I have since had the Saros Z70 in my home for several months, and was disappointed (but not surprised) that the robotic arm doesn’t make your life much easier. The arm’s pickup capabilities were advertised to cover four different types of obstacles and must weigh under 300 grams: socks, paper, small towels, and lightweight shoes (no pet toys yet). The arm does technically work sometimes — I’ve witnessed it successfully pick up sandals and socks — but other times, it completely misses or ignores obstacles altogether. The half-baked innovation had good intentions, but for now, is just another robot vacuum that is trying to do too much.

People more swayed by practicality than a hit-or-miss high-tech feature might find the bigger grab here to be the Z70’s incredible 22,000 Pa of suction power. That’s 12,000 Pa more powerful than the Roborock Qrevo Master, my favorite overall robot vacuum of 2024 that cleans with 10,000 Pa, and also beats the suction power of any Roomba I’ve tested by a long shot.
The Saros Z70 isn’t the only new 2025 Roborock vacuum
Roborock also announced two more flagship robot vacuum and mop combos in the Saros line that are armless, making each a much more digestible price to the average household. Since this story’s first writing in January, I was able to test both the Saros 10 and Saros 10R at home for several months. Both retail for $1,599.99 (in line with my original price prediction) but have been on sale for $1,299.99 toward the end of summer 2025. As it stands, I think the Roborock Saros 10R is the best robot vacuum you can buy currently.
Rather than relying on the rotating laser tower atop many robot vacuums alone to assess walls and furniture in the room, the Roborock Saros 10R maneuvers using dual-light 3D Time-of-Flight technology and AI-powered RGB cameras. That’s fancy talk for more meticulous 3D mapping of your home and more precise detection of small obstacles that may be lying in the cleaning path — so even without the arm, this is still a big step up in the autonomous navigation department. The AI itself is also upgraded for more accurate, ever-improving recognition of the trickiest obstacles, including small toys and loose, unfolded cables. It just can’t clean under them like the Z70, though that might be a no-brainer sacrifice depending on the price difference between the two.

Cleaning-wise, the Saros 10R cleans with 20,000 Pa of suction power, while the similar Saros 10 cleans with the same 22,000 Pa suction power as the Saros Z70. But to me, the biggest difference between the Saros 10 and Saros 10R is actually related to mopping — I compared both models head-to-head in my apartment to help you pick one.
