A full dust bag reduces a vacuum's suction power. Change or empty the bag before it's full. Lint, hair or thread that collects on bristles can interfere with the cleaning action of the brushes.

Use the vacuum's hose to remove lint or hair. To remove threads, clip them off or unravel them after disconnecting the plug.

To patch a hole in a vacuum hose, wrap duct tape around the area, make sure the seal is tight.
