iRobot Braava 380t Troubleshooting

Your mopping device does not move and lights will not turn on

Plug in device and wait for battery to fully charge before attempting to use. This problem could also be due to a faulty AC adapter. If the light on the AC adapter does not turn on, check the current of AC adapter with a voltmeter. In order to do this, plug the adapter into a power source, turn the voltmeter on, attach the red terminal of the voltmeter to the pin inside the plug of the ac adapter, attach the black terminal of the voltmeter to a ground (any piece of metal), and check for a current. If the voltmeter reads a current, the ac adapter is functional. If not, replace the ac adapter.

Replace battery with this guide

The battery may not be properly connected. Remove the bottom battery panel with a flat-head screwdriver and ensure that the wires are firmly plugged in.

The power button may be broken or have some kind of obstruction below the surface of the panel. The button may need to be replaced.

Your iRobot Braava 380t turns on but will not move

If your iRobot Braava 380t does not move at all, a possible reason is that the wheel tread has worn off. The wheel tread may need to be replaced.

If from the side view, you cannot see the wheels of the iRobot, the suspension spring may have failed. If so your iRobot will have trouble moving.

If your mopping machine will not move it might be because your wheels are broken. Replacing the wheels is a simple procedure.

The immobility of your device might also be due to a faulty wheel motor. This part can be found online and replaced fairly simply.

Your iRobot moves in an irregular pattern; going in circles, not turning

If the device isn’t turning or is moving in circles, one wheel motor could be burned out.

The wheel axles could be jammed with hair or other debris from normal operation. If so, remove debris with tweezers or other tools. If you are still unable to remove the debris, remove wheels to completely clean the wheel-axles assembly.

Ensure that the mopping cloth is firmly attached to the cleaning pad and that the cloth is not tangled. Disconnect and reattach the cleaning pad to the iRobot to ensure proper connection.

Irregular movement may be caused by a malfunctioning navigation cube or if the signal is interrupted. Make sure that no obstructions are in the line of sight of the navigation cube. If there are no obstructions then you may need to replace the navigation cube.
