Diagnostics For Your Robot Mower

There are a lot of sensors, controls, alarms, and other circuits built into our Wombat mowers.
But how do you check that everything is in working order?
You need a diagnostic tool that can help with robot lawn mower troubleshooting.
Something that can interface with the device, that tells you how all the sensors are working.
Fortunately the robotzoo Wombats have such a tool, onboard, that lets you look into the functions of the device.
Herein is a guide on how to use the diagnostic interface.
It will help you to troubleshoot any unexpected behaviours or issues that may be experienced.
Also, to test the fitness of the various sensors, and how they work.

What sensors are there?

Some mowers have a diagnostic screen.
Robotic mowers are equipped with the following sensors:
  • Boundary Wire Line Detection;
  • Charging Station Current.
  • Touch; Bump; Lift; Rain; Gyro – Pitch / Roll / Angle.
  • Internal Charge; Internal Motor.

Accessing the diagnostic screen

Press Home & Go immediately after turning on the mower.
To initiate the self-detection (diagnostic) program:
    • Release the Red emergency button.
    • Immediately press left two buttons.
(before the welcome message ends)

The diagnostic screen appears:
  • LL – Left Wire Signal
  • RL – Right Wire Signal
  •  L – Left Bump Sensor
  •  R- Right Bump Sensor
  • Gyro – Pitch/Roll/Angle
The following readings show:
  • NUL = No wire signal
  • IN = Inside the wire
  • OUT = Outside the wire
  • 0 / 1 = Inactive / Active

The wire sensors are installed in the undercarriage, near the front wheel. Note the following distances:
  • between the blades and the sensors
  • between the wheel edges and the sensors.

Specific posts on robot mower troubleshooting & diagnostics


Robotic mowers are sophisticated electronic devices, with sensors, circuits, controllers, motors and software.
Sometimes they don’t behave as expected, so robot lawn mower troubleshooting is important.
This is most often done by looking at the settings and making sure that they are all appropriate for the installation.
Sometimes, it can be due to a component that has become damaged.
That is why it is important to source your device from a local supplier.
One that can provide the advice and support required, if necessary.

What does robotzoo do?

Our clever devices help households do mundane chores and maintain the floors, windows, pools and lawns.
There’s a robot for almost every chore:
  • Automatic battery driven robotic lawnmowers;
  • Cordless pool cleaning robots;
  • Frameless glass detecting robotic window cleaners; and,
  • Self-emptying robotic floor vacs.
You can confidently source them all from the one responsible local supplier with a local warranty for every device.
