The grey fluff or debris you find inside a vacuum cleaner after cleaning is typically a combination of dust, dirt, hair, lint, and other small particles that the vacuum has picked up from the surfaces it cleaned. Here's a breakdown of what you might find in the grey fluff:
Dust and dirt: This is the most common component, consisting of tiny particles from the floors, carpets, and other surfaces in your home.
Hair: Human and pet hair can accumulate quickly in a vacuum cleaner, especially in households with shedding pets or individuals with long hair.
Lint and fibers: Fabrics shed lint and fibers, which can also be picked up by the vacuum.
Dead skin cells: People naturally shed skin cells, and these can end up in the vacuum cleaner.
Pollen and allergens: If you have open windows or doors, pollen and other allergens can be brought inside and end up in the vacuum cleaner.
Food particles: In the kitchen or dining areas, small food crumbs might be sucked up by the vacuum.
Miscellaneous debris: Depending on the specific areas cleaned, you might find small pieces of paper, plastic, or other debris in the fluff.
Remember that regular cleaning and emptying of the vacuum cleaner's dustbin or bag are essential to maintain its efficiency and suction power. It's also recommended to clean or replace the filters regularly to prevent dust and allergens from being released back into the air during vacuuming.
