Laresar Start Command / User Interface Failure

Robot vacuum powers on but will not start cleaning when the Start button is pressed or via the app.

This repair may involve working with high voltage components or water connections. Always unplug the appliance before removing any panels.

If you are not confident in your ability to perform this repair safely, we strongly recommend contacting a professional technician.

Possible Causes

Start button switch worn, Child lock enabled in app, Firmware glitch, Main PCB input circuit fault

Safety: Keep the robot on the dock while troubleshooting.

Check app settings: Ensure no child lock or schedule-only mode is enabled in the Laresar app.
Try alternative control: Start cleaning from the app if the physical button fails, or vice versa.
Restart robot: Power cycle the unit and retry.
If only the physical button fails: The button switch or top control board may be defective and require replacement.
