A vacuum cleaner is a household appliance 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. There are various types of vacuum cleaners, including upright, canister, robotic, and handheld models, each suited for different cleaning needs. Most vacuum cleaners are powered by electricity, although some portable models may use batteries. They often come with attachments like brushes and hoses to clean upholstery, corners, and hard-to-reach areas. Regular use of a vacuum cleaner helps maintain a clean and healthy living environment.
