Apparatus and method for receiving and holding debris in a collection chamber of a vacuum cleaner. The collection chamber has an inlet opening through which debris-entrained air enters the collection chamber. When the vacuum cleaner is off, an internal valve prevents debris from leaving the collection chamber through the inlet opening. The internal valve is movable from a first sealed position, in which the internal valve covers the chamber inlet opening, to a second unsealed position in which the internal valve does not cover the chamber inlet opening.

A cleaning robot including: a main body; a drive device; and a cleaning device equipped for wet-cleaning floors to be cleaned, wherein: the main body, on the side facing the floor to be cleaned, is assigned a receptacle unit, a first mop pad configured for wet-cleaning is fastened to the receptacle unit, and the cleaning robot is configured to autonomously exchange the first mop pad fastened to the receptacle unit for a second mop pad.

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 cleaning robot includes a machine body, a perception system, a control system, and a driving system; the perception system includes a laser distance sensor and a camera; the laser distance sensor is located on a top surface of the cleaning robot; and the camera is mounted on the cleaning robot through a mounting bracket, and a field of view of the camera includes a traveling direction of the cleaning robot. The camera apparatus is applied to the cleaning robot, and provides good shockproof performance and good stability. In addition, when a distance between optical axes of two cameras changes, the camera can be replaced and calibrated at any time, facilitating maintenance and repair.

The present invention relates to a robot cleaner and a method for controlling the same. The present invention provides a mobile robot and a method for controlling the same, the mobile robot using the rotational force of three or more rotary members as a moving power source thereof, wherein the mobile robot is controlled to effectively travel along a configured straight travel route and not to deviate from the configured straight travel route, or is controlled to immediately return to the configured straight travel route when deviating from the configured straight travel route.

The present application describes one or more map data transmission methods, cleaning devices and storage media. A method may comprise obtaining a first map data corresponding to a current cleaning position and a second map data corresponding to a previous cleaning position. Both the first and second map data may be divided into at least two map layers. The method may further comprise extracting a first map layer data from the first map data and extracting a second map layer data from the second map data. The method may further comprise obtaining the changed first map layer data with respect to the second map data of the same map layer; and sending the changed first map layer data to a computing device (e.g., a cloud server).

A floor cleaning machine with a base, which has a driven cleaning element, and an operating bar that is pivotably attached to the base via a joint and extends between a proximal end and an actuating end. The joint includes a bellows, which is coupled at its opposite ends to the base and the operating bar, a first supporting element, which is arranged inside the bellows and is attached to and points away from the base, and a second supporting element, which is arranged inside the bellows and is attached to and points away from the proximal end of the operating bar. A free end of one of the first and second supporting elements has a projection, while a free end of the other of the first and second supporting elements has a receiving recess that receives the projection and guides it for pivoting movement.

A floor cleaning machine having a cleaning element arrangement with inner and outer cleaning elements that include inner and outer cleaning bodies, respectively, that extend jointly in the cleaning body plane and have first and second receiving openings, respectively. The inner and outer cleaning elements extend from the inner and outer cleaning bodies, respectively, away from the cleaning body plane to one side thereof. The inner cleaning body is arranged in the second receiving opening. The output shaft extends with an output shaft section into both the first and second receiving openings. First and second eccentric elements are attached to the output shaft section and to the inner and outer cleaning bodies, respectively, so that when the output shaft is rotated, the inner and outer cleaning bodies perform eccentric movements that are phase-shifted with respect to one another.

A torque transmitting ball joint can include a spherical ball, a stem extending from the spherical ball, one or more pins coupled to the spherical ball, and a socket. The socket can define an opening sized to contain the spherical ball within the socket and one or more slots sized to accommodate a pin of the one or more pins. The one or more pins can be contained by the one or more slots and can translate within the slot as the spherical ball rotates relative to the socket about a pivot center. At least one of the one or more pins can abut a sidewall of its slot and transmit torque from the stem to the socket via the spherical ball when the stem and spherical ball rotates relative to the socket.

A cleaning apparatus may include: a main-body unit; and first and second dust units, which are alternately attachable to and detachable from the main-body unit. The main-body unit may include: one or more cleaning tools, which brush(es) up waste on a work surface; a main body rotatably supporting the cleaning tool(s); and one or more wheels rotatably supported by the main body and configured such that the cleaning apparatus is movable along the work surface via the one or more wheels. The first dust unit may include: a first container, which is detachable from the main body and is capable of collecting the waste brushed up by the cleaning tool(s). The second dust unit may include: an adapter, which is detachable from the main body; and a second container, which is detachable from the adapter and is capable of collecting the waste brushed up by the cleaning tool(s).
