The answer to 'how to clean vacuum' is to regularly maintain and clean your vacuum cleaner to keep it working effectively. This involves emptying the dust cup or bag, cleaning the filters, and removing any hair or debris from the brush roll and other components.
Over time, dust, dirt, and hair can build up in your vacuum, reducing its suction power and efficiency. Regular cleaning helps extend the life of your vacuum and ensures it continues to pick up dirt and debris effectively.
