Instructed by the Kress RTKn network, it navigates your lawn with centimeter-level accuracy. No need for boundary wire or fixed reference antenna to be installed on the lawn. The bullseye navigation algorithm ensures accuracy where lines of sight to the satellites are blocked by trees and buildings. Operated by the MAP™ (Mowing Action Plan) technology, it can maintain each zone independently and efficiently manicures lawns up to 1¼ acre large.

Centimeter-level positioning accuracy
Kress’s proprietary RTKn network delivers correction data to each robot mower without the need of any GNSS receiver antenna in the lawn.

Dead reckoning navigation
When lines of sight to the satellites are blocked by trees and buildings, accuracy is ensured by Kress’s proprietary algorithm that processes the mower’s inertial and odometry data.

Unique MAP™ (Mowing Action Plan) technology
MAP™ technology automatically determines the most efficient path to complete the hob and calculated the shortest route to the charging station from whichever position.

Precise multi-zone management
Kress’s MAP™ technology allows the maintenance of each zone independently.

Auto-leveling cutting disc
The blade-to-ground clearance is automatically adjusted to match any unevenness of the terrain, preventing the blade from scalping the turf.

Electronic cutting height adjustment
It allows to progressively trim overgrown grass down to the desired height, and to adjust the mowing height according to the season for a healthier grass.

Theft protection
In the unfortunate event that the robot mower is stolen, it will be possible to trace its position wherever it ends up.

Washable underbody
IPX5 rated, it resists sustained water jet sprayed from the nozzle of a water hose. (do not powerwash)

RBS™ Regenerative Brake System
When running downhill, the robot mower is slowed down by converting its kinetic energy into electricity that’s stored in the battery for longer runtime.

OAS (Obstacle Avoidance System)
Instead of bumping into unmapped obstacles, OAS detects them and steers the mower accordingly.
