Vacuum cleaner is an electrical appliance that uses suction to remove dust, dirt, and other debris from surfaces like floors, carpets, and upholstery. It works by creating a partial vacuum with a motorized fan, which pulls in air and particles into a container, such as a bag or dustbin, for later disposal. These devices range from domestic units for homes to powerful industrial versions for large-scale cleaning, with various models designed for specific needs, often including different attachments for versatile cleaning.
