- Applicable Models: VK8902DCAL, VK8903LHAY, VK8904LHA, VK8906/07DCAL, VK8801/02/03/04/07/10FHAY, VK8805/06/08FHY, VK8100LHAY , VK7901/02LHA, VK7100LHAY, VK6101/02LHAY.
- The automatic power-off function activates to help prevent damage when the dust bin is full. Empty the dust bin before using the vacuum. Make sure the dust bin is correctly attached to the main body before use.
- If you continue vacuuming when the dust bin is full, dust can flow back into the dust separator and reduce its separation performance. This allows dust to enter the motor directly, which can cause malfunctions like sparking. To prevent this, LG introduced a dust level detection function. When dust reaches a certain level, the vacuum alerts the user with an LED and buzzer, then turns off the power to prevent further operation.
- Dust level detection function.
- The filter check indicator on the hose blinks for 1 minute, and the vacuum sounds a chime. After 30 seconds, suction power drops significantly, and the vacuum automatically stops.
- The vacuum will not operate if the dust bin is missing or improperly attached to the main body. The red LED on the hose handle will blink, and the vacuum will sound a repeating chime.
- This vacuum features a dust compression system. The compression plate operates when the gear connected to the compression motor in the main body engages with the gear at the bottom of the dust bin. If the dust bin is removed, the compression gear is exposed, which can be dangerous for children. Therefore, the vacuum shuts off automatically when the dust bin is removed to prevent the gear from operating.
