Quick verdict
The Roborock Saros Z70 is the first mass-produced robot vacuum with a mechanical arm. Its five-axis OmniGrip arm folds out to pick up socks, tissues and slippers and put them in a storage zone you define, instead of just driving around them. Underneath the party trick sits a genuinely flagship cleaner — 22,000Pa suction, an ultra-slim 3.14-inch body and hot-water mop washing — for a $1,999.99 list price. Based on specs and independent testing, the cleaning is elite; the arm, for now, is a promising first draft that only works about half the time.
What is the Roborock Saros Z70?
Announced at CES 2025 as the flagship of Roborock’s Saros line, the Z70 is a robot vacuum and mop built around OmniGrip, a foldable five-axis mechanical arm with its own cameras, LED lighting and a weight sensor. When the robot spots a recognised obstacle, it marks the spot, picks the item up, carries it to a storage area you set in the app — a general storage box zone or a dedicated shoe area for slippers — then returns to clean the patch of floor it had blocked. For safety the arm ships disabled: enabling it takes steps in the app plus a button combination on the robot itself.
What the OmniGrip arm can — and can’t — pick up
The recognised list is short and specific: socks, small towels, tissues and sandals or slippers, each under 300 grams. Anything else, the Z70 treats as an obstacle to avoid, using its StarSight Autonomous System 2.0, which Roborock says recognises 108 object types and can navigate around items as small as 2cm. Independent testing by Vacuum Wars found the arm succeeded only about half the time across its three object classes, and measured real-world intake suction well below the headline figure. Roborock positions the arm as a feature that improves through software updates, and that framing is honest: today it is a glimpse of where home robots are going, not a finished tidy-up service.
Cleaning hardware and dock
As a cleaner, the Z70 wants for little. Suction is rated at 22,000Pa with a dual all-rubber, anti-tangle brush system. The body is just 7.98cm (3.14 inches) tall, so it slides under most furniture, and the AdaptiLift chassis climbs thresholds up to 4cm and lifts the mops up to 22mm on carpet. Dual spinning mop pads wash in hot water at the multifunction dock, which also empties dust, dispenses detergent, dries the pads with heated air and senses dirty water. The 6,400mAh battery is rated for up to 300 minutes of runtime, and a quiet mode runs as low as about 50dB. FlexiArm Riser side brush and mop arms extend reach into corners and along edges.
Pros and cons
- Pros: The only consumer robot vacuum with a gripper arm; top-tier vacuuming and hot-water mopping; near-flawless obstacle avoidance in independent tests; ultra-slim body fits under low furniture; dock automates washing, drying, emptying and detergent.
- Cons: $1,999.99 list price (the near-identical-cleaning Saros 10R costs far less); arm works on only four light object types and succeeded about half the time in testing; deep-carpet pickup tested below cheaper stablemates; the arm is off by default and needs deliberate setup.
Who should buy the Roborock Saros Z70?
Buy it if your floors are rarely clear, you hate pre-tidying before a robot run, and you enjoy owning first-generation technology that improves over time — the underlying cleaner justifies most of the price on its own. Skip it if you mainly want the best cleaning per dollar: Roborock’s own Saros 10R delivers comparable day-to-day cleaning for hundreds less, and every other flagship rival undercuts the Z70 while it waits for its arm to grow up.
Frequently asked questions
How much does the Roborock Saros Z70 cost? The list price is $1,999.99. Roborock’s own US store showed $1,699.99 when we checked in October 2026, and street prices move often, so check before buying.
What can the Saros Z70’s arm pick up? Socks, small towels, tissues and sandals or slippers weighing under 300 grams. Other objects are avoided, not moved.
How strong is the Saros Z70’s suction? It is rated at 22,000Pa. Independent bench testing measured lower real-world airflow than the rating suggests, though its overall vacuuming and mopping results still rank among the best tested.
Does the Saros Z70 work right out of the box? The vacuum and mop do, but the OmniGrip arm is disabled by default. You enable it in the Roborock app’s Robotic Arm Settings and confirm with a button combination on the robot, then set your storage zones on the map.
