The present disclosure discloses a cleaning robot and a roller cleaning device thereof. The cleaning robot comprises a shell and a roller cleaning device. The roller cleaning device comprises a flexible roller, a roller motor for driving the flexible roller to rotate, a water sink close to and in communication with a surface of the flexible roller, a water tank, and a sewage pressing member. The water tank comprises a filter member. One end of the water sink is in communication with the water tank through a sewage pipe at a position above the filter member, and the other end of the water sink is in communication with a clean water pipe at a position below the filter member. The water tank is connected to a vacuum pump, and the sewage pressing member squeezes the sewage in the flexible roller into the water tank when the flexible roller rotates.

A cleaning tray is provided for docking an extraction cleaner, including upright or robot extraction cleaners, for self-cleaning. The cleaning tray may include one or more sprayers for spraying a cleaning fluid toward a suction nozzle, brush chamber, and/or agitator of the extraction cleaner. Systems for self-cleaning extraction cleaners are also provided.

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.

A combination of a floor cleaner and a cleaning tray. At least a portion of a base of the floor cleaner is received by a reservoir of the cleaning tray. The floor cleaner further including an upright portion movable between an inclined use position and an upright storage position. The brushroll is powered by a brushroll motor. The brushroll motor includes a control circuit that controls the brushroll. The control circuit has a first switch that is open when the floor cleaner is in the upright position and closed when the floor cleaner is in the inclined use position. The second switch is in parallel with the first switch. The second switch is opened in response to the portion of the base being removed from the cleaning tray and the second switch is closed when the portion of the base is in the cleaning tray.

A cleaner according to the present disclosure includes: a mop module which includes a pair of spin mops that contacts a floor while rotating clockwise or counterclockwise when viewed from a top and is left-right symmetric with a virtual central vertical plane; a collection module which includes at least one collection unit that collects foreign substances from the floor at a position spaced apart from the mop module in a forward and backward direction, forms a collection space which stores the collected foreign substances, and is left-right symmetric with respect to the central vertical plane; and a body that connects the mop module and the collection module.

A cleaner includes a body, a left spin-mop module located on a left side of the body and a right spin-mop module located on a right side of the body, each of the left spin-mop module and the right spin-mop module being rotatable about a first rotational axis to perform mopping, a left spin-drive unit disposed on the left side of the body, the left spin-drive unit being configured to provide a force to rotate the left spin-mop module; and a right spin-drive unit disposed on the right side of the body, the right spin-drive unit being configured to provide a force to rotate the right spin-mop module. Each of the left spin-drive unit and the right spin-drive unit has a second rotational axis that extend in a direction different from the first rotational axis of the respective left spin-drive unit and the right spin-drive unit.

A cleaner includes a first cleaning module including a left spin mop and a right spin mop that come into contact with a floor while rotating in a clockwise direction or in a counterclockwise direction when viewed from an upper side, a second cleaning module that comes into contact with the floor at a position spaced apart from the left spin mop and the right spin mop in a forward-and-backward direction, a body supported by the first cleaning module and the second cleaning module, and a water supply module that supplies water to the first cleaning module. A water tank is disposed inside the body. Water supplied by the water supply module reaches the first cleaning module before reaching the floor.
