What testers say about the Roborock Saros Z70
The Roborock Saros Z70 is the first robot with a mechanical arm that rises from the top to move socks, cloths and slippers out of the way, on top of everything the flagship Saros 10R already has: an embedded lidar without a turret, a climbing chassis, two spinning mop pads that lift 0.9 inches and can stay behind in the station, and a station that washes in 176 °F water and doses detergent. Vacuum Wars gave it its award for the most innovative robot of mid-2025.
Mopping was a standout: on dried stains the second-highest score ever measured, 139 points against 103 for the Saros 10R and a 93 average, with the least residual water in the test. Debris of every size came off hard floors and carpet, the extending side brush handled corners well and the station empties the bin into a 2.7-liter bag and cleans itself. At under 3.1 inches it fits under most furniture.
The arm itself is the weak spot: it only recognizes paper balls, fabrics and one style of slipper, picked objects up sometimes and sometimes not in the tests, and did not always put them in the right place. The testers call the feature a glimpse of the future rather than a reason to buy today, and the price is among the very highest. The station dries the pads with 131 °F warm air. Anyone wanting the Saros 10R's equipment with the arm as a bonus can consider it once the price approaches the 10R's.
Pros
- Vacuums carpet and hard floors thoroughly, leaving almost nothing behind TechRadar ↗
- Mops very well, with a pad that swings out to clean along edges TechRadar ↗
- Its low, flat top lets it clean under furniture taller robots miss TechRadar ↗
- One of the best mopping results they tested, and floors stay only slightly damp Vacuum Wars ↗
- Avoided nearly every obstacle in their tests Vacuum Wars ↗
- Very complete app with multiple maps, a smart cleaning plan and pet features Vacuum Wars ↗
Cons
- Automatic tidying with the arm rarely worked, steering it by remote works better TechRadar ↗
- The review unit rattled while cleaning, and the dock can be noisy TechRadar ↗
- Very expensive, and models without the arm clean just as well for less TechRadar ↗
- Weak at getting embedded grit and flattened pet hair out of carpet Vacuum Wars ↗
- The arm often failed to pick up or place items, and knows few objects Vacuum Wars ↗
- Very small dustbin in the robot, because the arm takes up room inside Vacuum Wars ↗
