Understanding Edge-Cutting Behavior And Modes

Roborock robotic lawn mowers offer different edge-cutting behaviors depending on the selected mowing mode and PreciEdge accessory configuration.

(1) Different Mowing Mode Behaviors

Mowing Mode

Edge-Cutting Performance

Full Mode (Global Mowing)

After completing the main central area, the mower will perform two laps of edge mowing around the edge. *

Area Mode (Selected Areas Mowing)

Follows the same logic as Full Mode. *

Edge Mode (Area Edge Mowing)

The mower only focuses on the edge and performs one lap only.

*Note: In the [Preferences] settings for both Full Mode and Area Mode, you will find the Edge-Cutting toggle:

-Switch ON: The mower will perform the two-lap edge mowing.

-Switch OFF: The mower will only mow the main area and won't mow the edge.

(2) The Two-Lap Logic (Full & Area Mode)

When edge-cutting toggle is on, the mower performs two laps and follows a specific sequence to ensure maximum coverage:

  1. Outer Lap (First): The mower moves directly along the boundary line.

  2. Inner Lap (Second): The mower moves slightly inward to mow a second parallel lap.

(3) When & how main blades and PreciEdge Accessory work?

The blade operation depends on your specific model and whether the PreciEdge kit is equipped.
