  • Remove the Digital Motorbar and other attachments and clear any hair, dust, or debris tangled around the brush.
  • Use a cleaning brush or scissors carefully to cut away any entangled hair.
  • Ensure all parts are dry and reassemble.

Step 3: Check Battery Health and Connection

Ensure the battery is properly seated and connections are secure. If the battery appears swollen, damaged, or is more than 2-3 years old, consider replacing it with a compatible replacement.

After cleaning and replacing parts, fully charge the vacuum. Use it to see if the battery now lasts longer and the cleaning performance has improved.
