A floor buffer is an electrical appliance that is used to clean and maintain non-carpeted floors, such as hardwood, marble, tile or linoleum. It is also known as a floor polisher or burnisher if it is a high speed floor buffer with a pad that rotates at over 1000 RPM.
Somewhat resembling a large upright, wide-based vacuum cleaner with handlebar controls and requiring two-handed steering, a floor buffer or rotary floor machine as they are sometimes called, use one or more variable-speed circular rotary brushes to dislodge dirt and dust from flat surfaces. They have a large, round scrubbing pad spinning in a circle in one direction which is powered by a small motor, usually directly over the center of the pad.
Larger powered floor buffer machines are used in schools, hospitals, offices and public buildings. These have wheels and are powered to allow user to easily move and clean items stuck on floors. Scaled-down versions are available for home use and often sold as hard floor cleaner.
