Vacuum Not Charging

Symptoms

• LED ring on handle remains dark when placed on dock or connected via USB-C
• Battery percentage in the app does not increase after several hours
• LED ring shows amber briefly then turns off
• Machine powers on but shows critically low battery after overnight charging

Likely Causes

1. The vacuum is not correctly seated on the dock
2. The dock power adapter is not connected or the outlet is off
3. The USB-C charging port on the handle is blocked by debris
4. Battery has discharged completely and requires a longer recovery period
5. Dock charging contacts are dirty or corroded

Step-by-step Fix

1. Confirm the wall outlet powering the dock is live. Try plugging another device into the same outlet.
2. Remove the A9 from the dock and re-hang it, ensuring the charging contacts on the handle base align with the dock pins. You should feel a light resistance as the magnets seat.
3. Inspect the charging contacts on both the dock and the base of the A9 handle. Clean both surfaces with a dry cloth. Oxidation or dust on the contact pins is a common cause of charging failure.
4. If using the USB-C cable, try a different cable. Check the port on the handle for lint or debris and clear gently with a wooden toothpick.
5. If the battery discharged completely (the machine won't power on), connect via USB-C and leave for 15 minutes before attempting to power on. Deeply discharged batteries need a recovery phase before the LED activates.
6. Check the Monverta Home app — if the battery health reads below 20% capacity, the battery may need replacement.
