How a Vacuum Cleaner Works
The science is simple. It uses air flow to move things.
How Suction Is Created
The motor spins the fan. This lowers air pressure inside. Air rushes in to fill the gap.
How Dirt Is Pulled In
The rushing air grabs dust. Brushes help lift dirt from rugs.
How Dust Is Stored and Filtered
Dirt goes into the bin. Air goes out through the filter. The dust stays inside.
Vacuums work by creating low air pressure. A spinning fan sucks air and dirt into a bag while a filter traps the dust.

| 1 | Fan spins |
| 2 | Air rushes in |
| 3 | Dirt is trapped |
