Vacuum Cleaner

A vacuum cleaner 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.

    Teenagers who are never required to vacuum are living in one.
    Fred G. Gosman (20th century)

    With boys you always know where you stand. Right in the path of a hurricane. It’s all there. The fruit flies hovering over their waste can, the hamster trying to escape to cleaner air, the bedrooms decorated in Early Bus Station Restroom.
    Erma Bombeck (20th century)
