RADAR LAWN EDGE DETECTION
Twenty ZR is the new simple, compact, light, powerful and fast robot mower, which does not require the installation of perimeter wire.
The robot is equipped with the most innovative technologies, which allow it to manage and map the garden by learning its characteristics.
ZR technology integrates artificial intelligence systems with front mounted radar sensors, allowing the robot to detect grass, recognise obstacles at a distance (stationary and moving), edges and perimeters.
Once it’s finished a mowing session the Twenty ZR automatically returns back to the dock to recharge ready for the next scheduled mowing operation.

NAVIGATION
Using the front bumper mounted radar sensors paired with advanced algorithms the Twenty ZR can tell the difference between a lawn and other surfaces. As the mower moves around the lawn, it continuously uses advanced imaging techniques to assess what surface is ahead of it. Deciding as it goes whether to mow it or navigate away.
What are suitable lawn edges?
Walls, Fences & Buildings
Any solid wall, fence or solid structure more than 9cm tall.

The TWENTY ZR can detect hedges directly on a lawn edge.
Patios
