A method of delivering a glutinous substance to a workpiece from an end-effector comprises using the end-effector to rotate a brush relative to the workpiece about a rotational axis. The method also comprises, while rotating the brush relative to the workpiece about the rotational axis, urging the glutinous substance from the end-effector through a channel of a body of the brush from an axial inlet of the channel to an outlet of the channel, into contact with a thatch of bristles of the brush. Additionally, the method comprises using the end-effector to position the brush relative to the workpiece such that the glutinous substance in contact with the thatch is delivered onto at least a first surface and a third surface of the workpiece.

A cleaning element carrier for a toothbrush in a form of a disk has a back surface including a central depression covering at least 70% of the back surface and forming an edge at the border. The carrier's front surface includes at least one protrusion so that the front surface comprises two levels, wherein the area covered by the depression is larger than the area covered by the protrusion.

A cleansing device is proposed. The cleansing device may include an inner cleansing part coming into close contact with a cleansing target; an outer cleansing part provided outside the inner cleansing part; and a rotating part configured to rotate the inner cleansing part and the outer cleansing part relative to each other. The inner cleansing part and the outer cleansing part have at least one contact point.

A sweeping brush for an automatically moving cleaning device has a rotational axis receptacle for receiving a rotational axis of the cleaning device and at least one bundle receptacle that extends outwardly from a transition area on the rotational axis receptacle, which holds a bristle bundle having a plurality of bristles. The bundle receptacle is arched as viewed in an axial direction of the rotational axis receptacle. In order to optimize known sweeping brushes in terms of their service life and cleaning properties, the bundle receptacle is fabricated out of an elastic material.

A floor cleaner can include a housing adapted for movement over a surface to be cleaned and at least one edge cleaning brush provided on the housing. The edge cleaning brush includes multiple cleaning implements which rotate at different velocities. A gear system, such as a planetary gear system, can drive one cleaning implement at a lower speed than another cleaning implement.

A method of manufacturing a brush includes providing a core wire section having a proximal end and a distal end, and an integral tip on the distal end, forming a bristle element having a throughbore, and inserting the core wire section into the throughbore until the bristle element is received on the core wire section.
