The present disclosure discloses a cyclonic propping anti-hair-winding roller brush body, a floor brush and a vacuum cleaner. The cyclonic propping anti-hair-winding roller brush body includes a roller brush main body, at least one cleaning rib is arranged on a surface of the roller brush main body, a flow guide groove is formed in the cleaning ribs, the flow guide groove is formed in a side face of the cleaning ribs in a length direction of the roller brush main body, and the flow guide groove is located on one side facing an area where dirt entering the roller brush main body. When the roller brush main body rotates, the dirt can enter the flow guide groove and turn under an action of the flow guide groove.

A cleaning robot includes a housing and a roller brush. The housing is provided with a mounting cavity with an opening at its bottom. The roller brush is rotatably arranged in the mounting cavity and at least part of the roller brush is extended out of the mounting cavity. At least part of the cavity wall is transparent to form a transparent area, and a viewing area is set at a position of the housing and above the transparent area. The closed observation space is formed in the housing, and the observation space communicated with the viewing area and the transparent area, so that the user can observe the working condition of the roller brush inside the mounting cavity.

A vacuum cleaner having a hand unit and an elongated member having a nozzle end portion and a handle end portion. The vacuum cleaner has a valve arranged at the nozzle end portion, the valve having a valve member being movable between a first and a second position. In the first position the valve member directs an airflow from a floor nozzle to the hand unit while preventing an airflow to flow through the handle end portion. In the second position the valve member directs the airflow from the floor nozzle to the handle end portion and to the hand unit. Vacuum cleaning may be performed with the floor nozzle both when the hand unit is connected at the nozzle end and at the handle end.

A nozzle for a cleaner according to an aspect of the present invention comprises: a housing; and a rotation cleaning portion rotatably coupled to the housing and having a body part and a brush part which is coupled to the outer peripheral side of the body part. The brush part comprises: a first brush coupled to the outer peripheral side of the body part and extending in the radial direction of the body part; and a second brush disposed alongside the first brush. The first brush is disposed so as to come in contact with a floor surface prior to the second brush during the rotation of the rotation cleaning portion, and is less stiff than the first brush.

The present disclosure provides a surface cleaning apparatus that mechanically removes liquid and debris from a brushroll and stores the mechanically-removed liquid and debris onboard the apparatus in a first collection area. The surface cleaning apparatus also collects further liquid and debris from the brushroll by a source of suction including a vacuum motor or a pump and stores the collected liquid and debris onboard the apparatus in a second collection area.

A rolling brush assembly includes a rolling brush having a rolling brush roller, at least two brush bars, and a protruding strip extending lengthwise along an axis. Each brush bar extends lengthwise in a longitudinal direction of the rolling brush roller. The brush bars are arranged at intervals along a circumferential direction of the rolling brush roller with the protruding strip located between adjacent two brush bars. The at least two brush bars are fixed on the rolling brush roller in one of a flocking or an inserting manner. An engagement portion is formed between the brush bars and the rolling brush roller. A distance from an outer end of the engagement portion to the axis is less than a distance from an outer end of the protruding strip to the axis.

Systems and methods for providing an air agitator nozzle system are disclosed. In an exemplary embodiment, the system comprises a vacuum and a nozzle. The vacuum is configured to suck particles from a floor surface. The nozzle is configured to spray air at the floor surface to loosen the particles and to push the loosened particles toward the vacuum to be sucked from the floor surface.

A cleaner head for a vacuum cleaning appliance includes a housing which defines a suction chamber. The suction chamber has a suction inlet through which air enters the suction chamber, and a suction port through which air exits the suction chamber. The cleaner head includes a plurality of casters for supporting the cleaner head. Each caster is rotatable relative to the housing about a first axis which is perpendicular to the suction inlet. Each caster is also rotatable relative to the housing about a second axis perpendicular to the first axis. The cleaner head further includes a plurality of guide members for guiding into the suction chamber debris entrained within air drawn towards the suction inlet. Each guide member is arranged to rotate with a respective caster about the first axis.

A vacuum cleaner is disclosed. The vacuum cleaner according to the present disclosure includes a main body and a suction nozzle. The suction nozzle includes a housing, a driver, a rotating brush, and a detachable cover. A pressing button is mounted in the housing. The detachable cover is rotated about the rotational axis of the rotating brush to be mounted in the housing. The pressing button selectively blocks rotation of the detachable cover.
