A cleaning robot includes a main body and a cleaning module. The main body is configured to move on a floor along a travelling direction. The cleaning module includes a first shaft and some first roller sets. The first shaft is connected with the main body. The first shaft extends along a first axis perpendicular to the travelling direction. The first roller sets are separated from each other. Each first roller set includes a first bearing, a first tire and a first flexible structure. The first shaft penetrates through the first bearing. The first tire includes a first cleaning surface configured to abut against the floor. The first flexible structure includes a first inner surface and a first outer surface. The first inner surface abuts against the first bearing. The first outer surface abuts against the first tire. The first flexible structure has a first elasticity.

An autonomous mobile robot includes a body, a drive supporting the body above a floor surface, a light-propagating plate positioned on the body and having a periphery defining a continuous loop, light sources each being positioned to direct light through a portion of the plate to a portion of the continuous loop, and a controller to selectively operate the light sources to provide a visual indicator of a status or service condition of the autonomous mobile robot. The drive is configured to maneuver the mobile robot about the floor surface.

A roller assembly for a mobile cleaning system for cleaning a work surface can include a drive shaft, a sheath, a bushing, and a bushing shroud. The drive shaft can be rotatable about a drive axis, and the drive shaft can include a driven end and an opposite bushing end. The sheath can be supported by the drive shaft and the sheath can be rotatable with the drive shaft. The sheath can include a shell engageable with the work surface. The bushing can be located about the bushing end of the drive shaft. The bushing shroud can be connected to the bushing. The sheath and the drive shaft can be together rotatable with respect to the bushing and the bushing shroud, the bushing shroud can include an outer portion defining a first radius of curvature and a recessed portion connected to the outer portion.

Disclosed is a cleaning unit comprising a variable brush portion. The cleaning unit according to an embodiment of the present invention comprises a shaft capable of reciprocating along an axial direction, wherein a first cam protrudes from the outer circumferential surface of the shaft. In addition, the brush portion is arranged on the outer circumferential surface of a body member surrounding the shaft, and the brush portion includes a second cam engaged with the first cam. When the shaft is moved in the axial direction, the first cam pushes the second cam in a radial direction, whereby the brush portion may protrude in the radial direction. That is, as the shaft reciprocates in the axial direction, the length of the brush portion protruding from the outer circumferential surface of the body member may vary.

A cleaning appliance includes: a main body with a bottom side, the main body being assigned on the bottom side, which faces toward a floor to be cleaned, at least one cleaning body, the at least one cleaning body being mounted on the main body so as to be rotatable about an axis of rotation, the axis of rotation of the cleaning body being oriented perpendicularly to the bottom side. The at least one cleaning body is mounted in the main body such that, during cleaning, the axis of rotation is movable relative to the bottom side along a movement path which is oriented perpendicularly to the axis of rotation.

A cleaner is disclosed. The cleaner according to an embodiment of the present invention comprises a winding member. The winding member is rotated in the cleaner to wind up thereon long and thin trash that can be compressed, such as animal hair, fibers, etc., which is introduced in a dust accommodation container. An attachable/detachable frame is accommodated in the cleaner to be detachable. The winding member has a base which has the largest diameter and is inserted and coupled to a winding member coupling portion of the attachable/detachable frame. Trash such as hair, fibers, etc. wound on the winding member is placed on a coupling plate that is located above the winding member coupling portion. Therefore, when the attachable/detachable frame is detached, the trash in the form of hair or fibers wound on the winding member is also discharged out of the dust accommodation frame along with the attachable/detachable frame. Accordingly, user convenience can be improved.

A cleaner is disclosed. A dust storage container according to an embodiment of the present invention includes a winding member. The winding member rotates in the dust storage container to wind debris having a shape which is thin, long, and compressible, such as fur of an animal or fiber introduced into the dust storage container. Accordingly, a space occupied by the debris in the form of fur or fiber in the dust storage container is reduced. Therefore, the dust storage container can receive a large amount of debris so as to increase an operable time of the cleaner. Consequently, the convenience of a user can be improved.

An autonomous coverage robot includes a chassis, a drive system configured to maneuver the robot, and a cleaning assembly. The cleaning assembly includes a cleaning assembly housing and at least one driven sweeper brush. The robot includes a controller and a removable sweeper bin configured to receive debris agitated by the driven sweeper brush. The sweeper bin includes an emitter disposed on an interior surface of the bin and a receiver disposed remotely from the emitter on the interior surface of the bin and configured to receive an emitter signal. The emitter and the receiver are disposed such that a threshold level of accumulation of debris in the sweeper bin blocks the receiver from receiving emitter emissions. The robot includes a bin controller disposed in the sweeper bin and monitoring a detector signal and initiating a bin full routine upon determining a bin debris accumulation level requiring service.

In general, the present disclosure is directed to a hand-held surface cleaning device that includes a relatively compact form-factor to allow users to store the same in a nearby location (e.g., in a drawer, in an associated charging dock, on a table top) for easy access to perform relatively small cleaning tasks that would otherwise require retrieving a full-size vacuum from storage. A hand-held surface cleaning device consistent with aspects of the present disclosure includes a body (or body portion) with a motor, power source and dust cup disposed therein. The body portion also functions as a handgrip to allow the hand-held surface cleaning device to be operated by one hand, for example.

A cleaning device connects to a mobile device through an interface. The cleaning device includes a trigger mechanism which includes at least one plate body, two elastic members connect to the plate body, and a baffle mechanism resting on the plate body. The baffle mechanism comprises at least one baffle, a torsion spring, and a processing unit. The baffle defines a first elastic sheet and the plate body defines a second elastic sheet. When a pressure is applied on the mobile device, the plate body is driven to rotate the baffle to make the first elastic sheet on the baffle contact the second elastic sheet on the plate body. The processing unit produces a trigger signal to execute a function of function modules when the first elastic sheet contacts the second elastic sheet.
