A floor treatment facility includes a chassis, a running gear for guiding the chassis over a floor, a treatment facility for treating the floor, a suction mouth, and a guide for applying the treatment facility movably along a predetermined path in relation to the chassis. The path extends in a vertical direction in relation to the floor and the path encloses a predefined angle with a plane parallel to the floor when the floor-treatment facility is standing on an even floor. The angle is at most approximately 45°.

A nozzle part and a robot cleaner including same are disclosed. A nozzle part according to various embodiments of the present invention comprises: a brush for collecting waste such as hair; and a removing member for removing the waste, such as hair, that is stuck to the brush. The removing member more quickly rotates than the brush in the same direction to remove the waste, such as hair, that is stuck to the brush. Therefore, the waste such as hair can be easily collected, removed and captured. Thus, user convenience can be improved.

A cleaning accessory for a vacuum cleaner comprises a housing. At least one rotatable cleaning brush is rotatably mounted to the housing and configured to engage a surface to be cleaned. The at least one rotatable cleaning brush comprises at least one flexible cleaning element projecting outwards from a side of the housing. The at least one flexible cleaning element is arranged to rotate in a cleaning position and rotate in a disengaged position whereby the at last one flexible cleaning element engages the surface to be cleaned when rotating in the cleaning position and the at last one flexible cleaning element is remote from the surface to be cleaned when rotating in the disengaged position.

A moving robot and a controlling method thereof are disclosed. The moving robot includes a dust sensor that detects dust in air suctioned during cleaning, and a controller that performs control so that the robot performs cleaning while traveling over a traveling area distinguished into a plurality of regions. The controller stores, in the data unit, dust information detected by the dust sensor and a number of times of cleaning in each region. The controller also sets a cleaning region and a non-cleaning region based on cleaning data, which is calculated based on the dust information and the number of times of cleaning. This helps prevent cleaning from being repeated unnecessarily and allows for cleaning depending on the number of times of cleaning, despite a small amount of dust. Accordingly, an entire indoor area may be maintained in a constant clean state and cleaning efficiency may be enhanced.

The present invention provides unique portable or stationary hose retraction systems in a single compact unit having an elongated hose, a chamber or plenum for storing the hose, a primary vacuum source for creating suction in the hose, and a secondary vacuum source for retracting the hose into the chamber. Embodiments may include one or more switches located at a distal end of the hose for controlling the primary and secondary vacuum sources. Other embodiments include a movable robotic unit with a proximity generating signal at the distal end of the hose, whereby the robotic unit may withdraw the hose as needed during use, and the secondary vacuum source may retract slack in the hose during use, or may retract the entire hose and the robotic unit after use.

The present disclosure provides a cleaning brush and an intelligent cleaning device. The cleaning brush includes a shaft rod, a cylindrical member and at least one end member. The shaft rod is provided with two first ends which are opposite in an axial direction; the cylindrical member coaxially sleeves the shaft rod and is provided with two second ends which are opposite in an axial direction, and a brush piece is arranged on an outer surface of the cylindrical member; the at least one end member is installed on at least one of the first ends, and the end member is provided with a blocking structure for preventing an entanglement from excessively extending away from the cleaning brush; the end member and the first end are provided with installation structures respectively matching each other; and the second end of the cylindrical member, which corresponds to the end member, covers at least a portion of the end member.

A control system and method which automatically responds to a stalling motor due to a brush head binding or hanging event, and which automatically prevents backlash damage to the electronics when the brush head is freed from it's constraints.

A cleaning robot, a bristle control method and a bristle control device, and a computer storage medium are provided. The cleaning robot includes a robot body, an side brush assembly disposed on the robot body, and a controller disposed on the robot body and configured to control a target bristle of the side brush assembly to be limited in a designated area. In embodiments of this application, the target bristle of the side brush assembly is limited in the designated area to prevent, as much as possible, the target bristle from exceeding out of the cleaning robot and affecting the appearance of the cleaning robot.

An attachment for cleaning a socket is provided including a body with an insertion section of the body for insertion into the socket along an insertion direction and with a connection section of the body for connection to a suction inlet of a vacuum cleaner, the attachment including at least one cleaning element for mechanical cleaning of an inner surface of the socket. The attachment includes at least one bearing element attached to the body, wherein the cleaning element is rotatably mounted on the bearing element relative to the body about an axis of rotation aligned along the insertion direction, and at least one drive element attached to the body for automatically rotating the at least one cleaning element about the axis of rotation. A method for cleaning a socket with the attachment is also provided.

A hand vacuum cleaner has a dual first stage cyclones.
