STIHL SE122 Vacuum Cleaners

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. The dirt is collected by either a dustbag or a cyclone for later disposal.They are called vacuum cleaners because of their suction to pull in dirt, dust particles, and other undesirable materials. The same physics that powers them is what gave vacuum cleaners their name.
