How The Upright Vacuum / Vac Cleaner Works
A vacuum cleaner, commonly referred to as a "vacuum" or "vac", is a device that uses an air pump to create a partial vacuum to suck up dust and dirt, usually from floors, and optionally from other surfaces as well. The dirt is collected by either a dustbag or a cyclone for later disposal. Vacuum cleaners, which are used in homes as well as in industry, exist in a variety of sizes and models: small battery-operated hand-held devices, domestic central vacuum cleaners, huge stationary industrial appliances that can handle several hundred litres of dust before being emptied, and self-propelled vacuum trucks for recovery of large spills or removal of contaminated soil.
A home use upright vacuum is a self contained unit and can be stored in a small space for immediate use.
Here we have an example of a vacuum sharing a small storage space with a clothes steamer:
