A vacuum cleaner including a cleaner body including a motor configured to generate a suction force and a foreign substance collection chamber; and a suction head connected to the cleaner body. The suction head may include a drum brush, a one-way roller disposed in front of the drum brush, and a housing having a suction port. The drum brush and the one-way roller may be configured so that, when the suction head is moving forward on a surface to be cleaned, the drum brush and the one-way roller rotate so that foreign substances on the surface are suctioned by the suction force into the housing through the suction port to be guided to the foreign substance collection chamber, and when the suction head is moving rearward on the surface, rotation of the one-way roller is restricted to prevent the foreign substances suctioned into the housing from being discharged outside of the housing of the suction head through the suction port.

A cleaner head for a vacuum cleaner including an agitator in the form of a brush bar, the brush bar including a plurality of radially extending bristles and a sealing material disposed between the bristles. The sealing material extends over substantially the entire circumferential and axial extent of the regions of the brush bar between the bristles. The cleaner head further includes a housing defining a chamber which at least partially surrounds the brush bar, a dirty air inlet in a lower part of the chamber and a front opening that exposes the brush bar at the front of the housing. The brush bar is supported for rotation with respect to the housing and arranged in the chamber such that the brush bar seals against the housing thereby restricting flow of air through the front opening.

A ride on toy (10) comprising a vehicle body (12) having front and rear wheels (18). A seat (16) is provided on an upper surface of the body (120 on which a child can sit and a cleaning unit (14) is releasably secured to the vehicle body. The cleaning unit (14) is secured to the vehicle body (12) between the front and rear wheels (18) and includes a housing (38) having an internal chamber (46) such that the cleaning unit (14) picks up particulate matter from the floor while the toy (10) is moving and deposits it into the internal chamber (46).

A handheld vacuum device includes a blower configured to suck air; an air intake duct configured to allow the blower to suck air therethrough, thereby capturing rubbish on a floor surface, from an open edge thereof; wheels configured to be rotated in a first direction in conjunction with a forward movement of the air intake duct and to be rotated in a second direction which is a direction opposite to the first direction, in conjunction with a backward movement of the air intake duct; a brush body provided on a rearward side of the open edge of the air intake duct, and configured to be rotated so as to sweep rubbish on the floor surface; and a rotation mechanism configured to rotate the brush body based on the rotation of the wheels. The rotation mechanism is configured to rotate the brush body in the second direction when the wheels are rotated in the first direction.

A vacuum cleaner includes a foot assembly having a suction inlet thereon, a suction source in fluid communication with the suction inlet to produce a working airflow there through, and a dirt container in fluid communication with the suction inlet and suction source. The foot assembly further includes a body defined by a central portion and a pair of extension arms, a rotatable agitator on each extension arm, and a drive assembly configured to counter-rotate the agitators. The counter-rotating agitators are operable to cooperate with the suction source to direct dust and debris towards the suction inlet.

A cleaner head that includes an agitator in the form of a brush bar, the brush bar including a sealing material extending over the circumferential and axial extent of the brush bar, the sealing material including a tufted material, and a housing defining a chamber which at least partially surrounds the brush bar, a dirty air inlet in a lower part of the chamber and a front opening that exposes the brush bar at the front of the housing, the brush bar being supported for rotation with respect to the housing and arranged in the chamber, wherein a partition is arranged within the chamber between the brush bar and an outlet of the chamber, the partition extends transversely and divides the chamber into an agitating region and a settling chamber, and the partition includes a wall that extends tangentially to the brush bar and is inclined rearwardly.

A surface cleaning head for a surface cleaning apparatus includes a dirty air inlet, a dirty air outlet, and a dirty airflow path extending between the dirty air inlet and the dirty air outlet. The surface cleaning head also includes an automated valve assembly operable to open and place the dirty airflow path in fluid communication with ambient pressure. The automated valve assembly is adjustably opened based upon a suction level within the dirty airflow path. The automated valve assembly includes an adjustable valve, a sensor operable to measure the suction within the dirty airflow path, and a controller operable to control the adjustable valve based on the sensor measurement.

A surface cleaning head 100 for a surface cleaning apparatus includes a dirty air inlet 108, a dirty air outlet 112, and a dirty airflow path extending between the dirty air inlet 108 and the dirty air outlet 112. The surface cleaning head 100 also includes an automated valve assembly 116 operable to open and place the dirty airflow path in fluid communication with ambient pressure. The automated valve assembly 116 is adjustably opened based upon a suction level within the dirty airflow path.
