A "cleaner" is a person or device that removes dirt, stains, and impurities from surfaces. Cleaners can be found in various forms, including household products like sprays and wipes, as well as machines like vacuum cleaners. They are essential for maintaining hygiene and cleanliness in homes, offices, and public spaces. In professional settings, cleaners may work as part of a cleaning service or facility management team. They often use specialized equipment and cleaning agents to ensure that environments are safe and sanitary. Effective cleaning helps prevent the spread of germs and contributes to overall health and well-being.
