The present invention provides a cleaning unit, comprising: a columnar body part having a rotation guide opening formed on the outer circumferential surface thereof; a shaft installed to reciprocate a predetermined distance in the longitudinal direction thereof in a hollow formed in the body part; a drive part that protrudes from the shaft in the radial direction thereof; a brush part that has one side installed on the outer circumferential surface of the body part along the longitudinal direction thereof and rotates on the basis of the one side as a rotation axis; and a driven part that extends from the brush part toward the drive part, passes through the rotation guide opening, and is inserted into a rotation guide groove formed in the drive part. The rotation guide groove extends at a predetermined angle with respect to the longitudinal direction of the shaft, and as the shaft reciprocates, the driven part is guided to rotate by means of the rotation guide groove, and the brush is rotated by means of the rotation of the driven part. The cleaning unit may include a robot cleaner or a cleaner operated by means of a user's operation.

A brushroll for a vacuum cleaner includes a brush dowel having a plurality of bristles and a drive motor within the brush dowel for rotating the brush dowel in a first direction of rotation, wherein an armature and motor shaft of the drive motor counter-rotates in a second direction of rotation.

The present invention relates to the technical field of cleaning, in particular to a cleaning appliance, which comprises a cleaning appliance body. The cleaning appliance body includes a housing, two brush rollers disposed at the bottom of the housing, a drive mechanism disposed in the housing and configured to drive the two brush rollers to rotate, and a dust collector disposed on the housing; a suction port of the dust collector is disposed between the two brush rollers; and both rotation directions of the two brush rollers direct towards the suction port. The cleaning appliance provided by the present invention adopts a combined structure of the two brush rollers and the dust collector; both rotation directions of the two brush rollers direct towards the suction port; dust, particulate waste or flocks are gathered; the waste is sucked into the dust collector through the suction port between the two brush rollers.

A cleaner head for a vacuum cleaner includes a suction cavity having an opening through which debris enters the cleaner head, and an outlet. An agitator is mounted in the suction cavity in a cantilevered manner for rotation relative thereto. The agitator includes a core which is conical in shape and has a first, free end and a second end which has a larger diameter than the first end. The cleaner head includes an agitator engaging member for pressing against the agitator any debris which has become wrapped around the agitator.

An outer rotor motor includes an inner stator and an outer rotor. The inner stator includes a stator frame and a stator unit mounted to the stator frame. The outer rotor includes a shaft and a rotor unit fixed to the shaft. The stator frame is integrally formed from plastic as an integral structure and comprises a base and a hub extending from the base, the hub forms a chamber therein, supporting components are installed in the chamber, and the shaft extends into the chamber and supported by the supporting components such that the shaft is rotatable relative to the stator frame. In the present invention, the stator frame has an integral structure made of plastic which simplifies the structure of the motor and reduces the cost of the motor. The present invention further provides a vacuum cleaner that employs the motor.

A rotating cleaning element configured to be inserted in a cleaning head compartment of a robotic vacuum, the rotating cleaning element including: a drive end including a drive protrusion configured to engage a drive mechanism of the cleaning head compartment; a bearing end and a shroud configured to surround at least a portion of the bearing end to lessen an amount of hair and similar matter that reaches the bearing; and a central member extending between the bearing end and the drive end.

The present disclosure provides a floor cleaner that includes a replaceable component, such as a brushroll or a filter. The floor cleaner has a detection mechanism comprising a magnet on the replaceable component and a Hall Effect sensor positioned to detect the permanent magnet when the replaceable component is correctly installed on the floor cleaner. Operation of one or more electrically-powered components of the floor cleaner is prevented when the permanent magnet is not detected by the Hall Effect sensor.

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.
