I have a question about the physics of suction. How does a vacuum cleaner work?

A vacuum cleaner works by creating a partial vacuum in a chamber. The air is sucked out of the chamber by a fan, and the air is then pushed back in by the fan. This creates a partial vacuum in the chamber, which allows the fan to pull in more air. The air is then pushed out of the chamber by the fan, and the cycle repeats.
