A random orbit scrubber comprises a main body having a front end and a rear end, a squeegee assembly coupled to the rear end of the main body, and a cleaning head assembly coupled to the front end of the main body. The cleaning head assembly can include a cleaning element structured for contact with a floor surface. The cleaning head assembly can further include a motor that is operable to impart rotational and orbital movement on the cleaning element. The cleaning head assembly can also include one or more arcuate cleaning fluid manifolds each having a plurality of dispensing points to distribute cleaning fluid in one or more locations on top of and in front of the cleaning element. The arcuate cleaning fluid manifolds can include variable flow nozzles and can be mounted to a carriage that rotates about the cleaning head assembly.

A nozzle for a cleaner includes a nozzle body having a suction passage in which air flows. A water tank is detachably mounted on the nozzle body, and a rotation cleaning part is rotatably supported at a lower side of the nozzle body to receive water from the water tank for cleaning a floor. The water tank includes an outlet through which water is discharged, a valve configured to open and close the outlet, and an air hole configured to introduce outside air into the water tank. An air hole operation part is movably installed on the water tank to open and close the air hole.

A floor surface cleaning machine includes a suction mechanism disposed at a bottom side of a machine frame for suction of dust and dirt on the floor surface, a brush mechanism disposed at the bottom side of the machine frame rearwardly of the suction mechanism for brushing the floor surface with cleaning liquid, and a squeegee unit disposed at the bottom side of the machine frame rearwardly of the brush mechanism for gathering dirty liquid. Before brushing the floor surface, fibers may be removed from the floor surface together with the dust and dirt for preventing the fibers from being tangled up with bristles of the brush mechanism.

The present disclosure relates to the field of cleaning robot technology, and in particular to a base station which is adapted for cooperating with a cleaning robot having a mop member that is configured to mop a floor, the base station includes a base station body and a mop member cleaning device arranged on the base station body, and the mop member cleaning device being configured to clean the mop member; the base station further includes a cleaning fluid supply device configured to supply cleaning fluid for cleaning the mop member; and a dirty fluid collection device configured to collect the cleaning fluid after the base station cleaning the mop member.

Provided is a robot cleaner that travels along a virtual traveling line connecting a start point to a predetermined target point in a straight line. The robot cleaner includes a body having formed therein a space for accommodating a battery, a water container, and a motor, and a pair of rotation plates that have coupled to lower sides thereof, mopping cloths facing a floor surface, and are rotatably disposed on a bottom surface of the body, in which when a shortest distance between the body and the traveling line is greater than or equal to a predetermined reference distance, rotation speeds of the pair of rotation plates are different from each other.

Provided is a robot cleaner that includes a body having formed therein a space for accommodating a battery, a water container, and a motor, a pair of rotation plates that have coupled to lower sides thereof, mopping cloths facing a floor surface, and are rotatably disposed on a bottom surface of the body, and a virtual connection line connecting rotation axes of the pair of rotation plates to each other, in which a midpoint of the connection line moves while drawing a trajectory in a closed curve form on the floor surface in rotary traveling, thereby preventing a center of rotation of the robot cleaner from moving away from an origin of rotation.

A machine for cleaning surfaces comprises a main body and a handle portion configured to move the main body along a determined advancing direction. The main body is equipped with a cleaning brush positioned adjacent to the surface to be cleaned, and a first and a second squeegee element positioned at opposite sides of the cleaning brush. The main body provides, furthermore, a first and a second suction mouth positioned at the first and the second squeegee element, respectively, connected to a suction device by a suction circuit. This comprises a deviation device configured to alternately and selectively pneumatically connect the first suction mouth, or the second suction mouth and the suction device, and to pneumatically disconnect, instead, the other suction mouth.

A device (1) for automatically performing an activity, in particular for cleaning dirty surfaces, having at least one sensor (3) and at least one drive element (4). The drive element (4) divides the device (1) into a rear region (11) and a front region (12), on the basis of the intended direction of movement (B). The sensor (3) is a mechanical sensor which is arranged in the front region (12) of the device (1) and is used to determine, by contact with the floor, a change in the height of the floor.

A surface cleaning apparatus includes at least a recovery system for removing the spent cleaning fluid and debris from the surface to be cleaned and storing the spent cleaning fluid and debris. The recovery system is provided with a recovery tank having a removably strainer that is configured to strain large debris and hair out of the recovery tank prior to emptying the recovery tank.

A surface cleaning apparatus adapted for movement across a surface to be cleaned. The surface cleaning apparatus can dock within a storage tray and charge a power supply. Electrical contacts on the surface cleaning apparatus and the storage tray can be shielded when the surface cleaning apparatus is not docked within the storage tray. Furthermore, the storage tray can include a reservoir for a self-cleaning mode.
