Emitting a high pitched noise from the unit
If your HOBOT LEGEE is giving off a high pitched noise, remove the roller-brush from the LEGEE and attempt to run the vacuum without the roller-brush. If the the LEGEE works as normal without the roller-brush this indicates an issue with the existing roller-brush. Replacing the roller-brush can resolve the problem. You can purchase replacement roller brushes here.
If this does not resolve the issue please contact customer service via 0370038791 or customerservice@robotmylife.com.au.
