Software update for Robotic Lawnmowers (ROB S Models only)


Sometimes your ROB S robotic lawnmower needs an update of the software. With this firmware update you will receive all optimizations and new features that make your robotic lawnmower (ROB S600/ S400) even better; free of charge and quickly. 

You only need a computer (PC or Mac), internet access, a  Printer USB cable (USB-A to USB-B; see figure) and a Torx T20. You can find step-by-step instructions below. 

How it works:

Step 1:

To perform the update you need a computer with Windows 10 / Mac 10.10 or later. (Other systems are currently not yet supported).

Step 2:

Plug your robotic lawnmower into your computer. To do this you will need a standard USB printer cable (A plug to B plug) and, depending on the model, a Torx 20 screwdriver. The USB connection for the ROB S is in the battery compartment.

Step 3:

Now download the software file, run the program and follow the instructions. A stable internet connection is required for this. Your robotic lawnmower will soon be available again with the latest updates.

Release Notes:

After updating to the current version, the following functions and improvements are available:

March 2020

  • Spot Cutting. The spiral mowing function is ideal for hard-to-reach places, such as under a trampoline or garden furniture. This saves you tedious reworking.
  • CorridorCut. Narrow corridors from a width of 60 cm are no longer a problem for the robotic lawnmower. He doesn't even stop at dead ends. The only requirement - the guide cable must be laid in the affected areas.
  • FrostSense. Mowing frozen grass can be harmful to your lawn. Activating the frost sensor prevents your robotic lawnmower from starting to mow when the floor temperature is less than approx. 5 ° C, even if its schedule actually tells it to.
  • Inclines. The robotic lawnmower can now manage an incline of up to 35%.
  • Lawn Shield. The robotic lawnmower adapts the mowing frequency to the growth of the lawn.

June 2020

  • Fixed an unusual stopping and turning during the mowing process without external influence. Various optimizations that make your robotic lawnmower work even more reliably in different situations. Basis for upcoming new functions.
