Cleaners are professionals who are responsible for maintaining a clean and hygienic environment in a variety of settings, such as offices, homes, schools, and hospitals. They use specialized equipment and cleaning supplies to remove dirt, dust, and stains from floors, carpets, walls, and surfaces, and ensure that the space is presentable and free from harmful bacteria and germs. Cleaners may work independently or as part of a cleaning team, and may have a regular schedule or work on a one-time basis. They need to be detail-oriented, physically fit, and able to follow safety protocols, as well as have good communication and customer service skills.
