Generally, the interior of a building structure is provided with a certain internal space by the floor, walls, and ceiling and is blocked from the outside while maintaining constant insulation, soundproofing, and lighting to create a comfortable and safe space can be provided.
Life in an indoor space involves the inflow of dust from the outside due to a user's entry and the generation of a significant amount of foreign substances or dust during the user's daily living activities or the use of household items and electronic devices within the indoor environment.
Life in an indoor space contaminated with foreign substances or dust has become a factor in causing various diseases, including respiratory diseases. To address these issues, people often engage in daily cleaning routines and ventilate by opening windows. Meanwhile, the air in the indoor space can be freshened by ventilation, but in particular, dust settled on the indoor floor cannot be effectively removed by ventilation alone. Therefore, it was necessary to use a separate vacuum cleaner or mop to remove the dust.
Even when using a vacuum cleaner to remove dust from the floor, fine dust may still remain on the floor, which can cause respiratory diseases and allergies, especially for the elderly and children.
Moreover, when using a mop to clean the floor, it becomes very challenging for individuals who cannot easily bend their backs, such as the elderly or pregnant women, and even for healthy homemakers it could impose excessive strain on their backs.
