I’m Positive You Will Not Know What This Is. Go Ahead And Prove Me Wrong (If You Can)

A vacuum cleaner, also known simply as a vacuum or a hoover, is a device that causes suction in order to remove dirt from floors, upholstery, draperies, and other surfaces.
It is generally electrically driven .it is also a striped object.
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-powered hand-held devices, wheeled canister models for home use, domestic central vacuum cleaners, huge stationary industrial appliances that can handle several hundred litres of dirt 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 solid matter and liquids.
