Let the people around you think you're using the vacuum cleaner ...
A vacuum cleaner is a device that causes suction in order to suck up dirt / particles and dust from floors, upholstery, draperies and more. It is generally electrically driven.
The dirt is collected by a dustbag or a cyclone for later disposal. Vacuum cleaners, which are used in homes, as well as in the industry, there is a variety of sizes and models — small battery-powered hand-held devices handle several hundred liters of dust before being emptied, and self-propelled vacuum trucks for recovery of large spills or removal of contaminated soil. Specialized shop vacuums can be used to suck up both dust and liquids.
