For the best performance and latest features, keep your LawnMaster robot mower firmware up to date.

L10 October 2022 Update 1.4

This latest update fixes a bug in scheduling on the 4-hour duration alternate mowing days function when the rain sensor is triggered, and includes all previous firmware updates.


  1. Download the software file above and save it to a blank USB flash drive/memory stick. Do not change the filename. The filename should show as randomMower.bin - if the file has downloaded with a (1) or (2) in the filename, please re-name the file when you save it.
  2. Make sure that the battery indicator is green and has sufficient charge to perform the software update. 
  3. Turn off the robot mower at the switch underneath and place it upside down on a clean, soft surface. Now is also a good time to perform any routine maintenance such as checking and replacing blades. 
  4. Using a cross-head screwdriver, remove the screws from the battery compartment in the deck of the mower. 
  5. Turn the mower back on at the switch and wait for two beeps. 
  6. Insert the USB flash drive and listen for 4 beeps. All time setting lights on the control panel will flash green. The program is installing. Do not remove the USB stick while the program is installing. This may result in damage to your mower.
  7. When the update is finished (this may take several minutes), the mower will beep continuously. The flash drive can now be removed. The mower will beep twice indicating that the software update is complete. 
  8. Replace the battery cover and screws.

Here are some quick checks to make sure your mower is set up correctly:

Check that:

  1. The boundary wire ends are not stripped too thin - leave plenty of wire core to connect to the terminals

  2. The boundary wire ends are in the right terminals - wire running under the charging station plate to BLACK and wire running away from the charging station to RED

  3. The charging station is oriented so that the terminals are on the left and open end on right (as viewed from the centre of the lawn)

  4. There are no kinks, doubling back, loops or irregular angles along the boundary wire - remember that the robot will follow the exact path of the wire to return home to charge

  5. The wire is straight for 1 metre in front of and behind the charging station and that it is in line with the charging station, or the mower may fail to dock or crash into the charging station

  6. All connectors used in repairing or connecting extra lengths of boundary wire must be of the type supplied in the box (no chocbox connectors) and they should be fully clamped shut with pliers

If you're still having problems, please follow our interactive troubleshooting guide at the top of the page. At the end of guide there is the option to contact our technical team if your issue is still unresolved.
