Service

Up to 80% less hand weeding.

We bring our autonomous laser weeding robot to your farm and take care of most of the weeding. You need no staff and no machinery of your own for the robot's work. Only the remainder is left for hand weeding.

Inquire about deployment for 2027  Here's how it works

Precira Laser Weeding Robot in the vegetable field

No chemicals

Weeds are destroyed with the laser, without herbicides 

Fully managed

We handle the transport, deployment, and monitoring of the robot.

Fair billing

You only pay for the machine hours that we work on your field.

Process using carrots as an example

Two passes, well-timed

The right timing is crucial. We plan the deployments from your sowing date and come when the weeds are still small.

  1. Before the season

    Inquiry & planning

    We discuss your crop, area and sowing dates, check your bed system and reserve your deployment days.

    Together
  2. Day 0

    Sowing

    You sow as usual and tell us the sowing date. We plan the passes from that date.

  3. Day 7–10

    1st pass

    Our robot drives autonomously across your field, detects young weeds and removes them precisely with the laser. No chemicals, no tillage.

  4. Day 14–17

    2nd pass

    About a week later we come back and take care of the weeds that have germinated since.

  5. Afterwards

    Result & billing

    With good timing, the two passes take care of about 80 % of the hand weeding. Billing is based on machine hours.

    Together
Two passes within the first two weeks or so after sowing, the window in which weeds are easiest to control.
