Roborock Saros Z70

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 22 millimetres and can stay behind in the station, and a station that washes in 80-degree 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-litre bag and cleans itself. At under eight centimetres it fits under most furniture.

The arm itself is the weak spot: it only recognises 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 55-degree 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.

Each point sums up, in our words, the review of the test it names, and its link leads to that review. We do not summarise RTINGS or Wirecutter: their lists are linked above.
