A steam cleaner is a device that uses hot steam to clean and sanitize surfaces. It works by heating water to create steam, which is then released through a nozzle. This steam can effectively remove dirt, grime, and bacteria from various surfaces, including floors, carpets, and upholstery. Steam cleaners are often used in homes and commercial settings for deep cleaning. They are considered eco-friendly because they typically require little to no chemical cleaning agents. Many models come with different attachments for specific tasks, making them versatile tools for maintaining cleanliness in spaces like kitchens and bathrooms.
