A cleaning accessory for a vacuum cleaner comprises a housing having a first air inlet on an underside of the housing and an air outlet and a first airflow path between the first air inlet and the air outlet. The cleaning accessory also comprises at least one cleaning brush having at least one flexible cleaning element projecting outwards from a side of the housing. The cleaning accessory also comprises at least one side air inlet on the side of the housing and a second airflow path between the at least one side inlet and the air outlet. The at least one flexible cleaning element is arranged to engage a surface to be cleaned adjacent to the at least one side air inlet.

A nozzle of a cleaner includes a nozzle body, a rotation cleaning part having a rotation plate to which a rag is attached, a driving device provided in the nozzle body, a water tank, a water supply passage, and a water adjuster of which at least a portion is mounted on the nozzle body at a rear side thereof so as to be exposed to a rear surface or a top surface of the nozzle body. A user standing on the same floor surface as the nozzle body may manipulate the water adjuster by using his or her foot. The water adjuster can adjust an on/off operation and a rotational speed (e.g., rpm) of the pump motor.

A cleaning accessory for a vacuum cleaner comprises a housing. A rotatable cleaning brush is rotatably mounted to the housing. The rotatable cleaning brush has at least one flexible cleaning element projecting outwards from a side of the housing. The at least one flexible cleaning element is configured to rotate and engage with a surface to be cleaned. A dirt deflector projects from the side of the housing and is configured to surround at least part of the perimeter of the rotatable cleaning brush.

A nozzle for a cleaner includes a nozzle housing having a suction flow path through which air containing dust flows, a first rotation cleaning unit and a second rotation cleaning unit located on a bottom side of the nozzle housing, the first rotation cleaning unit and the second rotation cleaning unit being spaced apart from each other in a left-right direction of the nozzle housing, each of the first rotation cleaning unit and the second rotation cleaning unit having a rotation plate, a driving device located in the nozzle housing, and a water tank located on the nozzle housing, the water tank being configured to store water to be supplied to the first rotation cleaning unit and the second rotation cleaning unit. The water tank includes a first chamber, and a second chamber spaced apart from the first chamber in the left-right direction of the nozzle housing.

A self-driving cleaner includes a drive unit that drives movement of a cleaner body, a control circuit disposed in the cleaner body, a camera that captures an image in front thereof, an obstacle detection sensor that detects an object, and a rotational frequency sensor that detects a stuck state. The control circuit (a) identifies information about a target object that caused the stuck state, (b) receives information indicating whether the target object is to be cleaned, and (c) controls the drive unit and a suction unit, when receiving information indicating the target object to be cleaned, to perform a first mode where the space excluding the target object is cleaned first and, thereafter, the target object is climbed if receiving cleaning reservation and perform a second mode where the target object is climbed first and, thereafter, the space excluding the target object is cleaned if receiving a cleaning start instruction.

A nozzle for a cleaner has a nozzle housing including a suction flow path configured to allow air and dust to flow therethrough, A water tank is mounted on the nozzle housing to store water. The nozzle also has first and second rotation cleaning units arranged on a lower side of the nozzle housing. Each of the first and second rotation cleaning units include a rotation plate coupled to a mop. The nozzle includes a first driving device that has a first driving motor to drive the first rotation cleaning unit. The nozzle also includes a second driving device that has a second driving motor to drive the second rotation cleaning unit. Further, the nozzle has a water discharge port provided at a bottom of the nozzle housing to supply water in the water tank to each of the first and second rotation cleaning units.

A cleaning machine may include: a first brush comprising a first brush shaft extending in a left-right direction and a first brush body held by the first brush shaft; a second brush comprising a second brush shaft extending in the left-right direction and a second brush body held on the second brush shaft; a brush supporting member supporting each of the first brush and the second brush such that the first brush and the second brush are rotatable; a body supporting the brush supporting member such that the brush supporting member is pivotable; and a pivot mechanism configured to pivot the brush supporting member with respect to the body. At least the first brush may move with respect to the body in an up-down direction when the brush supporting member pivots with respect to the body.

A nozzle for a cleaner has a nozzle housing, and first and second rotation cleaning units arranged on a lower side of the nozzle housing and spaced apart from each other. Each of the first and second rotation cleaning units includes a rotation plate coupled to a mop. The nozzle includes a first driving device having a first driving motor to drive the first rotation cleaning unit. The nozzle also includes a second driving device having a second driving motor to drive the second rotation cleaning unit. Further, the nozzle has a water tank mounted on the nozzle housing to store water. The nozzle housing includes driving unit covers arranged to surround each of the driving devices. At least one of the driving unit covers includes a first protruding surface, and a second protruding surface positioned higher than the first protruding surface.
