A cleaning accessory for a vacuum cleaner comprises a housing. At least one rotatable cleaning brush is rotatably mounted to the housing and configured to engage a surface to be cleaned. The at least one rotatable cleaning brush comprises at least one flexible cleaning element projecting outwards from a side of the housing. The at least one flexible cleaning element is arranged to rotate in a cleaning position and rotate in a disengaged position whereby the at last one flexible cleaning element engages the surface to be cleaned when rotating in the cleaning position and the at last one flexible cleaning element is remote from the surface to be cleaned when rotating in the disengaged position.

Vacuum cleaner and cleaning accessory for a vacuum cleaner

A cleaning accessory for a vacuum cleaner comprises a housing having a first air inlet on an underside of the housing and an air outlet and a first airflow path between the first air inlet and the air outlet. The cleaning accessory also comprises at least one cleaning brush having at least one flexible cleaning element projecting outwards from a side of the housing. The cleaning accessory also comprises at least one side air inlet on the side of the housing and a second airflow path between the at least one side inlet and the air outlet. The at least one flexible cleaning element is arranged to engage a surface to be cleaned adjacent to the at least one side air inlet.

A cleaning accessory for a vacuum cleaner comprises a housing. A rotatable cleaning brush is rotatably mounted to the housing. The rotatable cleaning brush has at least one flexible cleaning element projecting outwards from a side of the housing. The at least one flexible cleaning element is configured to rotate and engage with a surface to be cleaned. A rotatable cleaning bar rotatably is mounted within the housing and the rotatable cleaning brush is rotatably coupled to the rotatable cleaning bar. At least a portion of the rotatable cleaning brush is seated within the rotatable cleaning bar or a drive mechanism coupled to the rotatable cleaning bar.

A vacuum cleaner comprises: a housing and a motor fan assembly mounted in the housing, the motor fan assembly arranged to generate an air flow. A removable dirt container is mountable on the housing and in fluid communication with a dirty air inlet and the motor fan assembly. A moveable dirt compactor is mounted in the dirt container and moveable between a stowed position and a dirt compacting position wherein the moveable dirt compactor is closer to one end of the dirt container in the dirt compacting position than in the stowed position. Wherein the dirt container comprises a primary handle for actuating the moveable dirt compactor with a first hand and a first auxiliary handle for allowing the user to grip with a second hand.

Cleaning device

A vacuum cleaner comprising: a housing; a motor-fan assembly arranged to generate an airflow between an air inlet and an air outlet; a dirt collection chamber mounted to the housing and having a door; and a filter assembly located within the dirt collection chamber, the filter assembly comprising a coarse filter having a first gripping portion and a fine filter having a second gripping portion, wherein the first and second gripping portions are capable of being gripped by a user, wherein the first gripping portion and the second gripping portion are isolated from an airflow path between the air inlet and the air outlet.

A vacuum cleaner comprising: a housing; a motor fan assembly arranged to generate an air flow; a dirt container in fluid communication with a dirty air inlet and the motor fan assembly; a moveable dirt compactor mounted in the dirt container and moveable between a stowed position and a dirt compacting position wherein the moveable dirt compactor is closer to one end of the dirt container in the dirt compacting position than in the stowed position, wherein the movable dirt compactor is shaped so as to allow dirt within the dirt container located on one side of the dirt compactor to pass to the other side of the dirt compactor; and a detector switch coupled to the moveable dirt compactor, the detector switch configured to open an electrical circuit and interrupt power supplied to the motor fan assembly when the moveable dirt compactor moves towards the dirt compacting position and urges dirt towards the one end of the dirt container.

A cleaning head connectable to a vacuum cleaner comprises a cassette removeably mountable on the cleaning head. A rotatable bar has projecting cleaning elements engageable with a surface to be cleaned and the rotatable bar is removeably mountable in the cassette. A first cassette mounting assembly is coupled to the rotatable bar at a first end with a first spindle. A second cassette mounting assembly is coupled to the rotatable bar at a second end with a second spindle. The first and second cassette mounting assemblies have removable cover portions for shielding the first and second spindles from debris and the first cassette mounting assembly is rotatably coupled to and removable with the first spindle.

Cleaning head

The present invention provides an upright vacuum cleaner () having an elongate body () and comprising a floorhead () on which the elongate body is mounted, the floorhead () having a first inlet () for dirty air, a wand having a second inlet for dirty air, a changeover valve () for selecting between a flow of dirty air from the first or second inlet, a dust collection chamber () also having a dirty air inlet (), a duct () for conveying said flow of dirty air from the changeover valve () to the dust collection chamber inlet (), and a source of suction power for drawing the dirty air from the first or second inlet through said changeover valve () and said duct () to the dust collection chamber inlet (). The changeover valve () comprises a linear conduit () positionable in fluid flow between the first inlet () for dirty air of the floorhead () and said duct (), the duct () having a sigmoid curve () from the changeover valve () to the dust collection chamber inlet (). When the conduit () is positioned in fluid flow between the first inlet () and the duct (), the flow of dirty air from the first inlet (), through the changeover valve () and the duct () to the dust collection chamber inlet () all lies in a plane.
