Suction cleaners, commonly known as vacuum cleaners, are devices designed to remove dirt and debris from floors and other surfaces. They work by creating a vacuum that pulls in air and particles, which are then trapped in a filter or bag. Suction cleaners come in various types, including upright, canister, and robotic models, each suited for different cleaning needs. These machines are powered by electricity and often feature attachments for cleaning upholstery, carpets, and hard-to-reach areas. Regular use of suction cleaners helps maintain cleanliness in homes and offices, contributing to a healthier environment by reducing allergens and dust.
