A surface cleaning apparatus has a rotatably mounted brush. The brush has a leading row of bristles, a trailing row of bristles and a hair blocking member between the trailing row of bristles and the leading row of bristles.

A cleaner head for a vacuum cleaner has an agitator rotatably mounted within a housing. The agitator has a main body having a wall, and bristles mounted adjacent the wall. Tips of the bristles are located at a first radial distance from a central longitudinal axis of the agitator. A tip of the wall is located at a second radial distance from the central longitudinal axis. The bristles have a first configuration in which the first radial distance is greater than the second radial distance, and a second configuration in which the first radial distance is less than or equal to the second radial distance. The bristles flex from the first configuration to the second configuration when the bristles move into contact with a surface to be cleaned, and flex from the second configuration to the first configuration when the bristles move out of contact with the surface.

A surface cleaning apparatus includes a rotatably mounted brush associated with a dirty air inlet. A plurality of bristles extend outwardly from a radial outer surface of the rotatably mounted brush. At least some of the bristles are encased in a sheath.

Disclosed is a vacuum cleaner. The vacuum cleaner includes: a cleaner main body configured to generate suction force; and a suctioner including a head having a suction inlet to suck dust by the suction force and a brush drum rotatably provided in the suction inlet to sweep dust on a floor. The brush drum includes convex portions projected from an outer circumferential surface of the brush drum and spirally extended in a rotational axial direction of the brush drum.

A system for polishing capsules includes a brush located at least partially inside a wall arranged around an axis (Z). The brush has bristles arranged around the axis (Z) to form a helical conveying ramp for the capsules. The lengths of the bristles of the brush are distinct and a protrusion is mechanically coupled to the wall to bend at least some of the bristles of the brush when the latter is in rotational movement around the axis (Z).

A cleaning head for a floor cleaner including a brushroll assembly configured to clean a surface to be cleaned and reduce brushroll maintenance, such as removing hair and debris wrapped around the brushroll assembly and removing debris from a bearing of the brushroll assembly. The brushroll assembly may comprise agitator members to assist in cleaning and maintenance.

A vacuum cleaner includes a main body and a suction nozzle that suctions up dust on the floor. The suction nozzle includes a housing, a driver, and a rotating brush. The housing includes an entrance through which the dust travels to the main body, a first shaft member, and a first rib disposed along a circumference of the first shaft member. The rotating brush includes a cylindrical body rotated by the first shaft member. The rotating brush also includes a brush member attached to an outer surface of the cylindrical body. The brush member rubs against the floor to direct the dust on the floor towards the entrance. As the brush member rotates, it also comes into contact with the first rib. The brush member includes a plurality of filaments. Some of the filaments are elastically deformed in the direction of the rotation axis upon contacting the first rib.

A brushroll dowel for a vacuum cleaner has a bristle stiffener protruding from a brush dowel. A plurality of stiffened bristles protrude from the brush dowel adjacent to the bristle stiffener, and a plurality of unstiffened bristles also protrude from the brush dowel and are non-adjacent to the bristle stiffener.

A surface cleaning apparatus includes a rotatably mounted brush associated with a dirty air inlet. A plurality of bristles extend outwardly from a radial outer surface of the rotatably mounted brush. A leading hair blocking member is provided adjacent a forward rotational side of the bristles, and a trailing hair blocking member is provided adjacent a rearward rotational side of the bristles.

A surface cleaning device for removing debris from a surface is described. The surface cleaning device comprises a cleaning head comprising a housing, wherein the housing defines an inlet and comprises brush chambers; at least one vent coupled to a top portion of the housing; and a sweeper assembly coupled to the housing and comprising brushes having bristles, wherein the cleaning head is configured create a suction with a surface by directing air flow into the housing through the inlet and out of the housing through the at least one vent.
