Roidmi Mode Button or Control PCB Fault

Vacuum randomly switches between power modes without user input.

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

Stuck mode button, Moisture ingress into control panel, Faulty control PCB, Electrical noise or interference on button lines

Safety first: Remove the battery before cleaning the control area.

Inspect the mode button area for signs of liquid spills or sticky residue. Wipe gently with a slightly damp cloth (unit powered off and battery removed), then dry thoroughly.
Do not spray cleaners directly onto the vacuum.
If random mode changes continue, the control PCB or button membrane is likely faulty and the main body or handle assembly should be replaced.
