A vacuum cleaner is an electrical 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 are equipped with attachments for cleaning upholstery, corners, and hard-to-reach areas. They can be used on various surfaces, such as carpets, hardwood floors, and tiles. Regular use of a vacuum cleaner helps maintain a clean and healthy living environment by reducing allergens and improving air quality.
