How can you use vacuum in a sentence?

Answer 1

Use the vacuum cleaner to remove loose dirt from the carpet.

OR:

The vacuum cleaner works by pumping air out through the exhaust ports and reducing the air pressure within its dust chamber, thereby causing air of relatively higher (atmospheric) pressure to rush inward through the end of the vacuum cleaner's hose to achieve equilibrium, dragging dust and debris with it into the dust chamber.

OR:

Having extracted as much air as possible from a sealed vessel, the vessel could be considered to contain a vacuum.

OR:

If one were to enucleate a bubble of 'true vacuum' in normal space, the boundaries of that bubble would expand outward at near-light velocities, essentially obliterating normal space (converting it to true vacuum, wherein matter as we know it cannot exist).
