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.

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 main housing and a driver. The driver includes a motor and a transmission. The motor is provided behind a rotating brush. The transmission transfers rotational motion of the motor to the rotating brush.

A cleaner head for a vacuum cleaning appliance, the cleaner head including a main body supporting an agitator. The agitator includes a rotatable cylindrical body that bears an elongate agitator formation for engaging a floor surface as the cylindrical body rotates. The elongate agitator formation includes a first agitator row extending around the cylindrical body from a respective first edge L of the cylindrical body towards its centre C in a first helical direction and a second agitator row extending around the cylindrical body from a respective second edge R of the cylindrical body towards its centre C in a second helical direction that is counter to the first helical direction, wherein the first agitator row includes agitators of a first material and wherein the second agitator row includes agitators of a second material that is different to the first material.

A cleaner head including: a brushbar arrangement including a first elongate portion, and a first curved portion located at a first end of the first elongate portion. The brushbar arrangement at least partially extends around a suction region. The cleaner head further includes a drive assembly configured to rotate the first curved portion and the first elongate portion.

An autonomous cleaning robot includes a drive system to move the autonomous cleaning robot about a floor surface, a cleaning head on a bottom portion of the autonomous cleaning robot, a side brush on the bottom portion of the autonomous cleaning robot, and a vacuum system in pneumatic communication with the opening. The cleaning head is configured to direct debris from the floor surface into the autonomous cleaning robot as the autonomous cleaning robot moves about the floor surface. The side brush is rotatable about a rotational axis forming a non-zero angle with a floor surface, and the side brush comprising an opening.

The invention relates to a floor cleaning machine, including a floor head, at least one cleaning roller, which is arranged on the floor head, a tank device, which is arranged on the floor head, and at least one sweeping element, which is associated with the at least one cleaning roller. To provide a floor cleaning machine of that kind, which has an optimized coarse dirt pickup function, the at least one sweeping element is arranged on the tank device and that at least a partial region of the tank device on which the at least one sweeping element is arranged is movable relative to the floor head in a cleaning operation.

A brushroll for a surface cleaning apparatus includes a brush dowel defining a central rotational axis which extends longitudinally through the brush dowel. The brush dowel includes bristle supports, sweeper supports, and a shroud surface extending between the bristle supports and the sweeper supports. A plurality of bristles protrude from the bristle supports.

Provided is a cleaner having improved cleaning efficiency. The cleaner includes a main body having a intake provided to suction an object to be cleaned and a suction device having a brush chamber that communicates with the intake and a brush accommodated in the brush chamber, wherein the brush includes a brush body rotatably coupled to the brush chamber, a blade protruding in a radial direction of the brush body, and prevention members formed to be inclined from a central portion of the brush body to opposite side ends of the brush body to prevent foreign substance introduced into the brush chamber from being wound around the blade.

A cleaning machine is provided, including at least one cleaning roller, a roller housing having a roller receptacle for the at least one cleaning roller, wherein the at least one cleaning roller is exchangeably positioned on the roller housing and the roller receptacle has an opening to the outside, a lid for closing the opening, and a locking device for fixing the lid to the roller housing, wherein at least one convex holding body is arranged on the roller housing, in that a pivotable bracket is arranged on the lid, in that at least one receptacle for the at least one holding body is arranged on the pivotable bracket, and wherein a release position of the pivotable bracket, the at least one holding body can dip into and/or exit the associated receptacle, and in a locking position, an exit of the holding body from the associated receptacle is blocked.

A vacuum cleaner including: 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.
