A vacuum cleaner is an electric device designed to remove dirt, dust, and debris from floors and other surfaces. It works by creating suction, which pulls in particles through a filter or bag. Vacuum cleaners come in various types, including upright, canister, and robotic models, each suited for different cleaning needs. Most vacuum cleaners have attachments for cleaning upholstery, corners, and hard-to-reach areas. They are commonly used in homes and offices to maintain cleanliness. Regular use of a vacuum cleaner can help improve indoor air quality by reducing allergens like dust mites and pet dander.
