Roborock RockMow Z120 LiDAR Robotic Lawn Mower

How does the wireless Sentisphere LiDAR navigation work?

The Roborock RockMow Z120 uses 360° 3D LiDAR coverage and VSLAM technology to map the terrain. The device records 200,000 points per second with a detection range of up to 70 meters and achieves centimeter-accurate positioning without the need for perimeter wires, whether in shade, under trees, or in complex parts of the garden.

• 360° 3D LiDAR scanning: Scans 200,000 points per second for instant orientation.
• Detection up to 70 meters: The wide laser range eliminates signal loss in complex terrain.
• Centimeter accuracy: Combined with VSLAM, it guarantees perfectly straight mowing lines.

How does the Vision-LiDAR Fusion system respond to obstacles?

The Vision-LiDAR Fusion Obstacle Avoidance system combines optical sensing with laser data. The mower identifies both static and moving objects in real time. By not just detecting obstacles but also interpreting them, it smoothly changes direction and avoids them in tight spaces regardless of the time of day.

• Camera and LiDAR fusion: Comprehensive obstacle evaluation for collision-free operation.
• Smooth avoidance: Dynamic real-time direction changes without unnecessary stopping.
• 24/7 operation: Reliable detection and stable performance in any lighting conditions.

What slope capability does the all-wheel drive provide?

The device features all-wheel drive (4WD / AWD) and patented Active Steering. This design combines high mechanical axle traction with precise front-wheel turning. It effortlessly handles slopes of up to 80% (38.7°), minimizes slippage, and protects the structure of the lawn.

• Slope climbing up to 80%: Stable driving and high torque on steep slopes.
• Active Steering control: Precise front-wheel movement prevents lawn damage.
• Four-wheel chassis: A robust construction ensures stability on slippery ground.

How do dynamic suspension and 6 blades mow dense grass?

An adaptive chassis with dual independent springs forms a stable base for the floating cutting deck. The system automatically follows the terrain contours and overcomes obstacles up to 8 cm high. Six durable blades with a 24 cm cutting width are powered by a strong motor that easily handles dense and lush grass.

• Obstacles up to 8 cm high: The suspended chassis absorbs bumps from holes and raised roots.
• Cutting head with 6 blades: Electrically adjustable cutting height from 20 to 70 mm.
• Floating cutting deck: Automatically adapts to ground contours for an even cut.

How accurate is the PreciEdge™ blade along edges?

The PreciEdge™ cutting module allows the mower to trim grass as close as 3 cm from garden walls and fences. On open lawn edges, the cutting head design ensures a smooth pass, creating a perfectly straight and clean cut without leftover uncut grass, and reducing the need for manual touch-ups.

• Cutting just 3 cm from walls: An advanced industrial solution for maximum edge cleanup.
• Clean finish: The PreciEdge™ blade design prevents tufts of grass from being left along edges.
• Smooth on-the-spot turning: Ensures quick direction changes and increases time efficiency.

What protective modes and zone management does the mower offer?

In the Roborock app, you can set up multiple independent zones and customize mowing schedules for each. The device includes a wildlife protection mode that pauses mowing during set hours to keep hedgehogs safe. Anti-theft protection comes in the form of a loud alarm, PIN code, and real-time 4G location tracking.

• Multi-zone management: Individual cutting settings for different parts of the garden.
• Wildlife protection: Considerate operation prevents collisions with nocturnal animals.
• 4G and PIN security: Instant machine location tracking and an acoustic alarm in case of unauthorized movement.
