[0002] With the development of modern technology, there are now a variety of floor cleaning tools, including brooms, mops, floor wipes, and vacuum cleaners. Vacuum cleaners are very common floor cleaning tools, but they are very noisy and very uncomfortable. Furthermore, they only clean up garbage by sucking it into a trash can.

[0003] Brooms, mops, and floor scrubbers are sweeping cleaning tools. They typically have a fixed cleaning part, and their cleaning performance depends on its ability to remove and absorb dirt. Since this cleaning part becomes contaminated upon contact with the dirty floor, its cleaning power gradually diminishes during subsequent cleaning. This makes it difficult to achieve a thorough clean, especially when sweeping large areas continuously. Consequently, these cleaning tools require frequent rinsing, which is quite cumbersome.

[0004] Since the roller of the cleaning tool needs to contact liquid when in use, it is inevitable that it needs to contact liquid during use, so the driving mechanism needs to be waterproofed.
