What are the ways to maintain vacuum cleaner and floor buffer?

To maintain a vacuum cleaner, regularly empty the dustbin or replace bags, clean or replace filters as needed, and check for clogs in hoses or brushes. For a floor buffer, ensure the pads are clean and in good condition, and inspect the machine for wear or damage after each use. Additionally, keep both appliances stored in a dry place and periodically check electrical components for safety. Regular maintenance will extend their lifespan and ensure optimal performance.
