A brushbar including: a body having a channel extending in the longitudinal direction and a retaining feature provided along each side of the channel and spaced away from a bottom, wherein a depth of the channel decreases in the longitudinal direction of the channel; an agitator element that includes a flexible strip and an agitator, wherein the flexible strip is disposed in the channel and extends between each retaining feature and the bottom of the channel such that the retaining features retain the flexible strip in the channel and the agitator extends radially from the channel; and a shim disposed between the flexible strip and the bottom of the channel such that the flexible strip abuts each retaining feature, wherein a thickness profile of the shim decreases in the longitudinal direction by an amount corresponding to the decrease in the depth of the channel.

A vacuum cleaner comprises a cleaning head having a suction nozzle adapted to be moved along a surface to be cleaned, and a hair collection assembly carried by the cleaning head and having a hair collection element adapted to collect hair from the surface to be cleaned as the cleaning head moves along the surface to be cleaned.

An agitator for a vacuum cleaner includes an agitator body and a resiliently deformable flap. The resiliently deformable flap includes a front face, a rear face, and one or more protrusions extending outwardly from the front face. An agitator for a vacuum cleaner includes an agitator body and a bristle strip and/or a plurality of tufts arranged in one or more rows along the agitator body. The bristle strip and/or a plurality of tufts includes a first bristle group including a plurality of nylon bristles and at least a second bristle group including a plurality of para-aramid bristles.

A method for manufacturing a flexible belt brush from a flexible brush element is disclosed. The axis of a cylindrical winding drum is aligned with a cylindrical winding base axis. A bottom winding of the flexible brush element is formed around the winding drum with the flexible brush element base adjacent to a winding drum outer surface and the flexible brush element surface disposed against the winding base. A winding ring is center aligned with the winding base and placed over the bottom winding. A top winding of the flexible brush element is formed around the winding drum adjacent to the winding ring. A compression ring is placed above the top winding. The winding bases are welded to form the base of the flexible belt brush.

A method of tufting, with a tufting tool, a brushroll dowel for a vacuum cleaner having a bristle stiffener protruding from the dowel and a bristle hole adjacent the bristle stiffener. The tufting tool includes a notch. The method provides a brushroll with bristles tufted into the bristle hole adjacent the bristle stiffener. A brushroll for a vacuum cleaner can be made using an injection molding process, with bristle stiffeners integrally molded with the dowel and a plurality of stiffened bristles protruding from the brush dowel adjacent to the bristle stiffeners.

A vacuum cleaner head having a housing, a suction opening, an agitator chamber located in communication with the suction opening, an agitator, a blade extending parallel to the agitator and mounted to rotate between a first blade position in which the blade does not engage the agitator, and a second blade position in which the blade engages the agitator to remove debris from the bristles during rotation of the agitator, a blade arm rigidly connected to rotate with the blade and extending from the blade pivot axis, and a cam surface movable between a first cam position in which the cam surface allows the blade to be in the first blade position, and a second cam position to displace the blade arm to rotate the blade to the second blade position.

A vacuum cleaner nozzle having a housing with a downward facing opening, a brush roll rotatably mounted to the housing at the downward facing opening, and a brush roll cleaner mounted to the housing. The brush roll cleaner includes a longitudinal bar extending along a longitudinal axis of the brush and pivotally connected to the housing at a pivot axis, an edge connected the longitudinal bar at a spaced location from the pivot axis and extending along to the longitudinal axis of the brush, and an arm extending from the longitudinal bar. The arm is configured to transmit a force to rotate the brush roll cleaner from a first position in which the edge does not contact the brush roll, to a second position in which the edge contacts the brush roll to remove debris from the brush roll as the brush roll rotates.

A rotating brush roller of a floor care device is a cylindrical rotational element including a hollow body as a central piece and end pieces to be supported via bearings in a brush housing of the floor care device. A spiral, outwardly open, receiving shaft or groove is provided in the outer circumferential surface of the hollow body for receiving and retaining therein a continuous spiral brush strip. The central piece is a self-supporting hollow body of plastic, into opposite ends of which the end pieces engage with a form-fitting connection. The receiving shaft for receiving the brush strip continues at least partially in the end pieces.

An autonomous cleaning robot (e.g., an autonomous vacuum) may clean an environment using a cleaning head that is self-actuated. The cleaning head includes an actuator assembly comprising an actuator configured to control rotation and vertical movement of a cleaning roller, a controller, and a cleaning roller having an elongated cylindrical length connected to the actuator assembly. The cleaning head also includes a computer processor connected to the actuator assembly and a non-transitory computer-readable storage medium that causes the computer processor to map the environment based on sensor data captured by the autonomous vacuum. The computer processor may determine an optimal height for the cleaning head based on the map and instruct the actuator assembly to adjust the height of the cleaning head.

A cleaner head for a vacuum cleaner includes a suction cavity comprising 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 having a first, free end, a second end remote from the free end, and upstanding helical ridges extending between the free end and the second end, and a row of bristles located between the helical ridges and inclined relative to the core in a direction extending towards the free end of the core.
