The Roborock Saros Z70 is the first mainstream robot vacuum with a mechanical arm that picks up objects from the floor. The five-axis OmniGrip arm extends from the robot body to grab socks, small toys, and lightweight items weighing up to 0.66 pounds, placing them aside before vacuuming and mopping the area underneath. This review covers what the arm actually delivers in practice, alongside the 22,000Pa suction and 3D ToF LiDAR navigation that handle the core cleaning work.

Beyond the headline feature, the Saros Z70 shares the same ultra-thin 3.14-inch profile as the rest of the Saros lineup. The StarSight navigation uses machine learning to recognize 108 different objects, and the self-emptying dock handles dust collection, mop washing with hot water, warm air drying, and detergent dispensing. The built-in "Hello Rocky" voice command lets you start cleaning without opening the app or connecting to Wi-Fi.
Product Overview
The OmniGrip mechanical arm is what separates the Saros Z70 from every other robot vacuum on the market. When the robot detects a recognized object on the floor during its cleaning path, the arm extends from a protected flap on top of the unit, grasps the item, and moves it to a designated spot. The arm handles items up to 300 grams, which covers most small obstacles that would otherwise force a traditional robot to navigate around or get stuck on.

In practice, the arm works best on flat, lightweight objects like socks and small stuffed toys. Irregular shapes and heavier items still require manual pickup before running the robot. The arm folds flat when not in use, keeping the 3.14-inch profile intact for cleaning under furniture.
The dual spinning mop pads handle wet cleaning with the VibraRise system, lifting 22mm when carpet is detected. The AdaptiLift chassis crosses thresholds up to 40mm for tiered configurations and 30mm for standard door frames, keeping the robot moving between rooms without getting stuck.
Technical Specifications
The Saros Z70 packs strong hardware into its 350 x 353 x 79.8mm frame at 4.9kg:
- Suction power: 22,000Pa HyperForce with automatic carpet boost
- Battery: 6,400mAh with up to 300 minutes runtime (180 minutes typical)
- Dustbin: 180ml onboard, 2.7L disposable bags in dock
- Water tanks: 590ml detergent, 4.23-quart clean water, 3.17-quart dirty water
- Navigation: 3D ToF LiDAR with VertiBeam lateral sensors, recognizes 108 objects down to 2x2cm
- Threshold crossing: 40mm tiered, 30mm standard, chassis lifts 10mm
- Noise level: 50dB quiet mode, 60dB standard mode
- OmniGrip arm: five-axis, lifts up to 0.66 pounds (300 grams)
- Dock dimensions: 381 x 475 x 488mm

The dual all-rubber main brushes prevent hair tangles, and the extending edge brush reaches along baseboards and into corners. The SmartPlan 2.0 AI system optimizes cleaning routes based on room layout and detected dirt levels.
Connectivity and Smart Home Integration
The Saros Z70 connects over 2.4GHz and 5GHz Wi-Fi through the Roborock app. The app provides multi-floor mapping, virtual barriers, no-go zones, and SmartPlan 2.0 custom cleaning schedules. The onboard RGB camera enables live video monitoring and the "Cruise to Check on Pets" feature for remote pet monitoring.

Voice control works with Alexa and Google Assistant, plus the built-in "Hello Rocky" command handles basic functions like starting cleaning or returning to dock without any network connection. For advanced automation, the robot integrates with Home Assistant through the Roborock integration, letting you trigger cleaning from presence sensors, schedules, or other smart home events. You can customize obstacle avoidance behavior for up to 50 objects ranging from 10x10cm to 100x100cm through the app.
Real-World Use Cases
The Saros Z70 addresses specific household scenarios effectively:
- Families with young children benefit most from the OmniGrip arm, which picks up scattered socks and small toys before vacuuming rather than pushing them around or getting tangled
- Pet owners get the 108-object recognition system that identifies and avoids pets, plus the video monitoring feature for checking on animals during the day
- Multi-story homes use dedicated floor maps with separate cleaning preferences, virtual barriers, and schedules for each level
- Large floor plans take advantage of the 300-minute maximum battery life that covers significantly more area than the 180-minute Saros 10R
- Low-furniture homes get thorough cleaning from the 3.14-inch profile that reaches under couches and beds

The self-emptying dock handles mop washing at 176 degrees Fahrenheit, warm air drying, dust emptying, and detergent dispensing. Some dock models support direct water line connection for truly hands-free operation over extended periods.
Setup and Getting Started
Place the dock on a flat surface near a power outlet. Download the Roborock app, create an account, and connect the robot to your Wi-Fi network. The initial mapping run uses the 3D ToF LiDAR to scan your entire home, building a floor plan you can then customize with room labels, no-go zones, and furniture markers.

After mapping, configure the OmniGrip arm settings to specify which objects it should attempt to pick up. Set cleaning schedules, mopping intensity, and virtual barriers for each room. The robot learns your home layout over multiple runs, improving its navigation efficiency. Firmware updates install automatically through the app.
Final Thoughts
The Roborock Saros Z70 pushes robot vacuum design forward with the OmniGrip mechanical arm, even if the feature works best on specific object types rather than everything on your floor. The 22,000Pa suction, 3D navigation, and self-emptying dock deliver strong core cleaning performance, and the 300-minute battery life handles larger homes comfortably.

The smaller 180ml dustbin is a tradeoff for the arm mechanism, but the 2.7L dock bag compensates for most households. For buyers willing to invest in the premium price point, the Saros Z70 offers the most capable robot vacuum available in 2026, especially for homes where floor clutter is a recurring problem.

Frequently Asked Questions
What can the Roborock Saros Z70 OmniGrip arm pick up?
The five-axis OmniGrip mechanical arm picks up small objects weighing up to 0.66 pounds (300 grams), including socks, small toys, and lightweight items left on the floor. The arm folds flat when not in use and extends only when the robot detects a recognized object in its path.
How does the Saros Z70 differ from the Saros 10R?
The Z70 adds the OmniGrip mechanical arm for object pickup, has a slightly larger 180ml dustbin versus the 10R 270ml, and includes the SmartPlan 2.0 AI cleaning system. Both share the same 22,000Pa suction and 3.14-inch height. The Z70 offers 300-minute max battery life compared to the 10R 220 minutes.
Does the Saros Z70 work with Home Assistant?
Yes. The Saros Z70 works with Alexa, Google Assistant, and integrates with Home Assistant through the Roborock integration. It also supports the built-in Hello Rocky voice command for basic operations without Wi-Fi.
How quiet is the Roborock Saros Z70?
The Saros Z70 operates at 50dB in quiet mode, which is roughly the volume of a normal conversation. Standard cleaning mode reaches about 60dB. This makes it one of the quieter robot vacuums available.
Can the Saros Z70 connect directly to a water line?
Some dock configurations support direct water line connection for hands-free water refilling. The standard setup uses a 4.23-quart clean water tank and a 3.17-quart dirty water tank that require manual refilling.
