My Robot Mower is going round in circles

Quick answer

If your robot mower is going round in circles, this is usually caused by an issue with the boundary wire, charging station setup, debris affecting the wheels, or signal interference.

Follow the checks below to identify and resolve the issue.

Before you begin

Before checking your robot mower:

  • Switch off the mower
  • Remove any grass, dirt, or debris from the mower
  • Check that the charging station has power
  • Check whether any changes have recently been made to your garden, boundary wire, or charging station position


Steps

1. Check your garden setup

A common cause of the robot mower going round in circles is an issue with the charging station or boundary wire installation.

Check the charging station:

  • The charging station should be installed on flat, level ground
  • The station should face outwards towards the mowing area
  • There should be enough clear space around the station to allow the mower to leave and return correctly

  • Check the boundary wire:
    • Make sure the boundary wire has not been moved, damaged, or disconnected
    • Check the charging station indicator light for any warnings

  • If the charging station light is flashing, this may indicate that the boundary wire is broken or disconnected.

    To check the boundary wire:

    1. Inspect the wire around your garden for visible damage.
    2. Check that the wire is securely connected to the charging station.
    3. Repair any damaged sections using the repair connectors supplied with your mower.

  • For further guidance, see the article on installing the boundary wire and charging station correctly.




2. Check underneath the robot mower for dirt or blockages

Grass, mud, and debris around the wheels can affect how the mower moves and may cause it to turn continuously.

To check:

  1. Switch off the mower.
  2. Turn the mower over carefully.
  3. Check the wheels for trapped grass, dirt, or debris.
  4. Remove any build-up before restarting the mower.

Make sure the wheels can move freely.

3. Check for signal interference

If another robot mower is being used nearby, it may be using the same boundary signal and causing interference.

To resolve this:

  1. Change the boundary signal on your charging station.
  2. Select either S1 or S2 on the charging station.
  3. Select the same signal on the robot mower.
  4. Confirm that the selected signal LED is displayed on the mower.

Using a different signal from nearby robot mowers can help prevent interference.

Frequently Asked Questions

Why is my robot mower spinning in circles?

The most common causes are boundary wire issues, incorrect charging station positioning, debris affecting the wheels, or signal interference from another robot mower.

How do I know if my boundary wire is damaged?

If the charging station indicator light is flashing, this may indicate a broken or disconnected boundary wire. Inspect the wire around your garden and check the connections at the charging station.

Can another robot mower affect mine?

Yes. If two nearby robot mowers use the same boundary signal, interference can occur. Changing your mower signal to S1 or S2 can resolve this.

Why does my robot mower keep turning in the same direction?

This can happen if the mower detects an incorrect boundary signal, has restricted wheel movement, or is affected by interference.

What should I do if my robot mower is still going round in circles?
