The Roborock Saros Z70 takes home cleaning to new heights. It combines powerful suction with the first mass-produced robotic arm that can move small obstacles.
At just 7.98 cm tall, it easily slides under furniture. Its OmniGrip™ 5-axis arm lifts items up to 300 grams, clearing socks, tissues, and sandals before vacuuming.

The vacuum delivers 22,000 Pa of HyperForce® suction. It uses dual anti-tangle brushes and StarSight™ Autonomous System 2.0 for navigation. This system combines LiDAR, dual cameras, and AI to create 3D maps of your home.
The Z70 avoids obstacles effectively and returns to clean missed spots. Its FlexiArm™ technology ensures corner-to-corner cleaning coverage.
The Multi-functional Dock 4.0 automatically empties the bin, washes the mop, and recharges the vacuum. Despite its high $1,899 price tag, it offers outstanding performance. Smart-home integration and strong privacy features make it ideal for tech-savvy homeowners wanting minimal cleaning effort.
Roborock Saros Z70 Review: Design and Build Quality
The Saros Z70 features a sleek, minimalist design with an ultra-slim 7.98 cm profile. This allows it to clean under sofas and low cabinets with ease.
Its circular body houses a powerful HyperForce® motor delivering up to 22,000 Pa of suction. This ranks among the highest in consumer robotics.
The vacuum is built from matte-textured polycarbonate that resists fingerprints and scratches. Both the brush assembly and dustbin detach easily for cleaning.
The standout feature is the foldable five-axis OmniGrip™ mechanical arm. This arm takes up just 10% of the space of previous robotic arms and folds flat when not in use.
Roborock Saros Z70 Review: Mechanical Arm
The Saros Z70 is the first mass-produced vacuum with an integrated robotic arm. This arm can pick up and move small objects weighing up to 300 grams.
It handles socks, crumpled tissues, and sandals with ease. Using AI-powered cameras on both the arm and front bumper, it identifies items and plans the best path. It grips objects gently before placing them in a “Store Box” or user-chosen location.
Early testers found the arm works well for common household clutter. However, it slows overall cleaning by about 10-15%, especially in crowded rooms.
The arm reliably picks up socks and small towels under 300 grams. Irregular or soft items like tangled cables or plush toys sometimes confuse the sensors.
The arm moves smoothly when deploying and retracting. Some users suggest adding a “pickup-only” mode for areas with multiple objects.
Roborock Saros Z70 Review: Cleaning Performance
With 22,000 Pa HyperForce® suction, the Z70 excels on all floor types. It easily lifts dust and pet hair from tile, hardwood, and low-pile carpets in a single pass.
Its dual all-rubber brush design prevents hair tangles. Anti-tangle systems on both main and side brushes reduce maintenance for pet owners.
The FlexiArm™ riser side brush extends under cabinets and along baseboards. This ensures thorough edge cleaning, with over 95% coverage after two passes.
The vacuum’s AdaptiLift chassis adjusts height by up to 5 mm. This allows it to cross thresholds and area rugs without losing suction or getting stuck.
Roborock Saros Z70 Review: Navigation and Mapping
StarSight™ Autonomous System 2.0 combines several sensors for navigation. It uses LiDAR, dual cameras, and structured light sensors to build real-time 3D maps.
The system tracks rooms, furniture, and obstacles, adjusting its cleaning path as needed. In busy homes, it marks obstacles during the first run and returns later to clean missed areas.
This approach reduces the need for user-initiated remapping by 80%.
App Control and AI Customization
The Roborock Home app lets users label rooms and set no-go zones. Users can also teach the arm which items to move and where to place them.
The AI recognition system improves over time through cloud-based updates. Currently, it can identify socks, sandals, tissues, towels, and some toys.
Roborock Saros Z70 Review: Docking and Maintenance
The upgraded dock does more than just empty the bin into a disposable bag. It also washes and dries the mop pad at 80°C, killing common bacteria.
The 6,400 mAh battery fully recharges in 150 minutes. The dock optimizes charging based on upcoming scheduled cleaning sessions.
Roborock recommends replacing HEPA filters every 2-3 months and brushes every 6-8 months. Replacement parts cost between $20-30 each.
The arm’s joints need a quick wipe-down every 50 hours to prevent dust buildup. The included microfiber cleaning kit makes this simple.
Roborock Saros Z70 Review: Privacy and Security
Roborock prioritizes privacy with on-board processing for arm operations. Video footage is stored locally and encrypted before any upload.
The vacuum meets TUV Rheinland privacy standards. A child-lock mode disables the arm, and a safety stop button halts all movement immediately.
Smart Home Integration
The Z70 works with Alexa, Google Assistant, and Apple HomeKit through Matter 1.4. This enables voice commands and status checks.
IFTTT support allows custom triggers. For example, you can set the arm to pick up items when you leave home or schedule auto-emptying after every third cleaning.
Value and Alternatives
At $1,899, the Saros Z70 sits at the premium end of the market. It costs about $600 more than high-end models like the Ecovacs T10 Omni.
However, its unique arm, 3D mapping, and multifunctional dock offer features no other robot currently provides. This makes it valuable for busy homes with frequent clutter.
If you don’t need obstacle relocation, consider the Roborock S7 MaxV Ultra at $1,099. It still offers excellent suction, self-emptying, and mop-washing at nearly half the price.
Roborock Saros Z70 Review: Conclusion
The Roborock Saros Z70 marks a major advance in autonomous home cleaning. Its mechanical arm isn’t just for show—it reduces pre-cleaning preparation and reaches hidden areas.
While its speed and price may give some pause, the Z70’s advanced vision, AI mapping, and multifunctional dock showcase Roborock’s innovation. For those wanting cutting-edge convenience—a “tiny butler” that vacuums and tidies—this flagship model delivers an impressive all-in-one solution.
