A steam mop is a cleaning device that uses steam to sanitize and clean hard floors. It heats water to create steam, which is then released through a cleaning pad. This steam helps to loosen dirt, grime, and stains, making it easier to wipe away without the need for harsh chemicals. Steam mops are effective on various surfaces, including tile, laminate, and hardwood floors. They often come with different attachments for cleaning carpets or upholstery. Many users appreciate the quick drying time and the ability to kill bacteria and allergens, making them a popular choice for households.
