A robot cleaner includes a main body, a water tank including a turbidity sensor and a water level sensor, and a pair of rotary mops configured to move the main body while rotating in contact with a floor. A drive motor rotates the pair of rotary mops and a nozzle supplies water from the water tank to the rotary mop. A rotary mop controller varies an output current of the drive motor based on signals from the water tank sensors. A controller determines whether the water tank is contaminated based on the output current of the drive motor received from the rotary mop controller.

A surface cleaning apparatus having a fluid delivery system and a fluid recovery system is provided with a housing including an upright body and a base coupled with the upright body. Cleaning fluid and electrical wiring can be routed between the upright body and the base via a yoked spine section of the upright body.

A wiping object cleaning device for a floor mopping machine belongs to the technical field of cleaning appliances. The wiping object cleaning device includes a bucket body, and further includes a water conveying mechanism for conveying water to a wiping object of a floor mopping machine. The water conveying mechanism conveys water during cleaning, and stops conveying water during water removal. The wiping object cleaning device is able to clean a mop of a floor mopping machine efficiently, wide in application range, suitable for different wiping objects of floor mopping machines, and low in production cost.

A cleaner includes a body including an insertion slot facing a floor and an installation space inside the body. The cleaner includes a dust housing detachably connected to the body. The dust housing includes a collection opening surface and a storage space that stores foreign substances collected through the collection opening surface. The cleaner has an agitator rotatably connected to the dust housing and exposed through the collection opening surface. The cleaner also includes a driving apparatus that rotates a driving coupler, which drives a driven coupler coupled to the agitator. The cleaner includes a lever located on either the driving coupler or the driven coupler. The lever selectively attaches or separates the driving coupler and the driven coupler. Manipulating the lever separates the driving coupler and the driven coupler and allows the sweep module including the agitator to be removed through the insertion slot in the body.

A maintenance station for maintaining a cleaning robot includes a housing, a cleaning structure, and a liquid supply assembly. The housing includes a guiding platform configured to guide the cleaning robot to park. The cleaning structure is arranged on the housing and positioned corresponding to the guiding platform. The cleaning structure includes a tank body and a cleaning protrusion. The tank body defines a groove, the cleaning protrusion is arranged in the groove, and the cleaning protrusion is configured to clean a cleaning piece of the cleaning robot. The liquid supply assembly is arranged on the housing, the liquid supply assembly defines a liquid supply port, the liquid supply port is positioned above the cleaning structure and configured to supply liquid that flows into the groove by gravity.

A sweeping and mopping integrated household intelligent robot includes a host machine and a base station. Dust bins are arranged in the host machine. A mopping mechanism is arranged at the bottom of the host machine. A cleaning system and a dust collection system are arranged in the base station. The cleaning system is used for cleaning the mopping mechanism; and the dust collection system is used for recycling garbage in the dust bins. The sweeping and mopping integrated household intelligent robot of the present disclosure has excellent obstacle crossing capability, achieves a better mopping effect by virtue of rolling mops with double cloth-bundled rollers, provides a strong dust collection force and has a variety of optional work modes; the rolling mops of the host machine are automatically cleaned by the base station; and a base station dust bag can be replaced quickly and conveniently.

A nozzle for a cleaner includes a nozzle housing that has a suction flow path that allows air containing dust to flow therethrough. The nozzle also includes a driving device including a driving motor. Further the nozzle includes a rotation cleaning unit including a rotation plate which is connected to the driving device at a lower side of the nozzle housing. The nozzle also includes a mop attached to a lower side of the rotation plate. In addition, the nozzle includes a water tank mounted on an upper side of the nozzle housing and configured to store water. The water tank is separable from the nozzle housing. An upper side wall of the water tank forms an upper surface of the nozzle when the water tank is mounted on the nozzle housing, and a portion of a bottom wall of the water tank is configured to surround the driving device.
