  • Patent number: 8407849
    Abstract: A cleaning tool includes a mop which includes at a lower end a mop head with a wiping object. The mop includes a mop rod formed of an inner rod and an outer rod and a drive mechanism is used to convert the telescoping motion of the mop rod to rotation motion of the mop head. The drive mechanism is a variable speed drive mechanism. As a result, the mop head of the cleaning tool achieves different rotation speeds under dry working condition with a lower resistance compared to washing conditions with a higher resistance. During washing, the mop head is washed rotationally at a lower speed, and the washing operation is conducted through depressing the mop rod.
