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 without hot air. Anyone wanting the Saros 10R's equipment with the arm as a bonus can consider it once the price approaches the 10R's.

Roborock Saros Z70 specifications
The numbers that matter first, then every fact by group. As published by the maker or the store we read it from.
The side brush swings out in a corner or along a baseboard, so the dust there is swept in too. On this model: from the maker's product text, not from a specification table.
yes
Suitable for pet hair
When it matters
Dogs and cats that shed.
Long-haired pets, whose hair wraps around a brush.
Without pets, ordinary hair and dust need nothing special.
Source: derived, no source of its own · checked on Oct 2
Whether the robot copes with pet hair: a brush that hair does not wind around and a dock that empties the bin for you. Where the maker does not say so itself, we read it from those two.
yes
Dirt detection
When it matters
Entrances and kitchens, where dirt gathers in one place.
Pets that leave hair in a favorite spot.
If dirt is spread evenly, a normal pass cleans it just as well.
The robot leaves the mop at the dock before it vacuums a carpet, so the carpet never gets wet. On this model: from the maker's product text, not from a specification table.
yes
Dock11 facts
Empties the dust bin
When it matters
Pets, sand or a large home, which fill the bin every run.
Dust allergy, since you rarely touch the dust yourself.
In a small home with little dust, emptying the bin by hand takes a moment.
The dock collects dust in a bin instead of a disposable bag. No bags to buy, but you empty it yourself. On this model: Assumed, not a stated fact: the maker's full specification does not name it, so we take it as no.
How hot the dock washes the mop. Above 140 °F (60 °C) grease comes off, which is what keeps a mop from smelling. On this model: from the maker's product text, not from a specification table.
176 °F (80 °C)
Dries the mop
When it matters
Mopping often, since a damp mop in the dock starts to smell.
Humid rooms, where a mop dries slowly.
If you take the pads off and wash them yourself, you will not miss it.
