A robot cleaner and a control method thereof are disclosed. A robot cleaner, according to an embodiment of the present invention, comprises: a tilt sensor module; a distance sensor module; and a light amount sensor module. Each piece of sensed information is transmitted to a lifting information calculation module. The lifting information calculation module calculates information on whether the robot cleaner is lifted, by using each piece of the transmitted information. If it is calculated that the robot cleaner is lifted off a floor, a power module is stopped. In addition, if it is calculated that the robot cleaner is not lifted off the floor, the power module is driven. Accordingly, when a user lifts the robot cleaner, injuries to the user caused by operation of a drive module can be prevented.

A robot vacuum cleaner and a control method therefor are disclosed. A robot vacuum cleaner according to an embodiment of the present invention comprises an acceleration change sensor module and a distance sensor module. Each piece of detected information is transmitted to an obstacle-passing information calculation module. The obstacle-passing information calculation module uses each piece of transmitted information so as to calculate information about whether an obstacle is present on one side of the robot vacuum cleaner and information about whether the robot vacuum cleaner can pass the obstacle on the one side. When the inability of the robot vacuum cleaner to pass the obstacle on the one side is calculated, a power module is driven so that the robot vacuum cleaner avoids the obstacle. Therefore, the robot vacuum cleaner can be prevented from going on an obstacle such as a carpet. In addition, the robot vacuum cleaner can be prevented from passing an obstacle such as a door sill so as not to leave a cleaning area.

A floor processing device has a floor processing element, a detection device for detecting a surface parameter of the floor surface, and a data processing device. The data processing device has a data memory, which stores a recommended use belonging to a surface parameter of the floor surface for using a specific floor processing element. The data processing device retrieves the recommended use from the data memory and transmits it to a user via an interface. The data processing device compares the size of a first surface area that has a first surface parameter with the size of the remaining surface areas of the environment, which have a surface parameter that deviates from the first surface parameter, and retrieves the recommended use from the data memory corresponding to the surface parameter that corresponds to the largest surface portion from the entirety of the surface areas.

Disclosed is a drainage system for an automatic cleaning storage base of an electric mop. The automatic cleaning storage base of the electric mop comprises a casing member having a cleaning tank. The drainage system comprises a drain valve; an outlet end of the drain valve is connected to the outside of the casing member, and an inlet end of the drain valve is connected to the cleaning tank; the drain valve has a switch, and the switch is provided with a first rack; the drain valve is further provided with a duplex gear and a second rack; the duplex gear has a gear portion with a larger outer diameter to mesh with the first rack, and the duplex gear has a gear portion with a smaller outer diameter to mesh with the second rack.

A cleaner head for a cleaning appliance, including an agitator rotatable about an axis; a housing having a front side, a rear side and first and second sides which extend between the front side and rear side, said housing at least partially defining a chamber. The chamber at least partially surrounds the agitator, the chamber having a dirty air inlet and a dirty air outlet. The chamber includes an opening for permitting access to and removal of the agitator from the chamber and a cover cooperatively associated with the housing for permitting access to the chamber through the opening. The cover is movable to an agitator access position to permit the agitator to be removed from the chamber through the opening in a direction substantially orthogonal to the axis of the agitator and in a direction which is substantially parallel to a plane of the surface to be cleaned.

A mobile cleaning robot can include a body and a cleaning assembly. The body can include a suction duct. The cleaning assembly can be operable to ingest debris from a surface of an environment. The cleaning assembly can include a dustpan engageable with the surface to direct debris toward the suction duct. The dust pan can be movable with respect to the body.

A cleaning assembly for a cleaning robot is provided. The cleaning assembly includes a motor, a transmission mechanism coupled with the motor, and a cleaning device comprising a shaft having a first gear coupled with the transmission mechanism and a cleaning module mounted to an end of the shaft. The transmission mechanism is configured to drive the shaft to rotate through the first gear. The shaft is configured to move axially. The cleaning module is configured to clean a surface area.
