Abstract: A vacuum cleaner nozzle (N) for cleaning a surface. The nozzle (N) has a first brush (FB) along a first side of the vacuum cleaner nozzle (N), the first brush (FB) having a first brush holder (FBH), and a second brush (SB) along a second side of the vacuum cleaner nozzle (N), the second brush (SB) having a second brush holder (SBH). The second side of the vacuum cleaner nozzle (N) is adjacent to the first side of the vacuum cleaner nozzle (N). According to one aspect of the invention, the second brush holder (SBH) is at a larger distance from the surface than the first brush holder (FBH). Preferably, the second brush (SB) is at an angle of less than 30° with regard to a vertical. The invention also provides a vacuum cleaner having such a vacuum cleaner nozzle (N).

Abstract: A separation device for separating a cyclone chamber from a collection chamber of a cyclonic separator has a guide member that includes a leading end, a trailing end, and a guide surface. The guide surface guides debris entrained in an airflow in the cyclone chamber in a helical path about an axis of the separation device and into the collection chamber. The guide surface extends about the axis of the separation device through an angle of less than 360 degrees for allowing debris in the cyclone chamber to also pass into the collection chamber from the cyclone chamber in an axial direction. The leading end of the guide member is at an angle between 30° and 60° towards the cyclone chamber with respect to the axis of the separation device to promote a helical flow of air and debris flowing over the guide surface.

Abstract: A vacuum cleaner head has a base and a suction opening in the base. An array of flexible flaps protrudes from the base. The flexible flaps are configured to act on a surface to be cleaned. The flexible flaps are spaced from each other to allow the passage of detritus therebetween in a predefined arrangement. The predefined arrangement of the flexible flaps is configured to promote a non-linear flow path through the array of flexible flaps between an end of the base and the suction opening. A gap between first and second rows of flaps is substantially equal to or greater than a space between adjacent flexible flaps in each of the first and second rows.

Abstract: The present invention relates to a nozzle (1) for a vacuum cleaner. The nozzle (1) has a base (3) having an edge (4, 5) and a suction aperture (11) in the base (3). At least one flexible flap (24, 26) protrudes from the base (3) between the edge (4, 5) and the suction aperture (11). The flexible flap (24, 26) has first and second sections (32, 33) separable by an opening (35). The first and second sections (32, 33) are urged towards each other when the nozzle (1) is moved in a first direction in which the edge (4, 5) is a leading edge to close the opening (35) or tend the opening (35) towards closure, and the first and second sections (32, 33) are biased away from each other when the nozzle (1) is moved in a second direction in which the edge (4, 5) is a trailing edge to open the opening (35) or to further open the opening. The present invention also relates to a vacuum cleaner comprising a nozzle (1) for a vacuum cleaner.

Abstract: The present application relates to a nozzle for a vacuum cleaner. The nozzle comprises a body (2) and a base (3). The base (3) has a longitudinal axis, and at least two cleaning sides (17, 18) configured to act on a surface in respective cleaning conditions. The base (3) is rotatable around a rotational axis (A-A) that is parallel to the longitudinal axis of the base to move the base (3) between the respective cleaning conditions.

Abstract: The present invention relates to a separation device (14) for separating a cyclone chamber (15) from a collection chamber (16) of a cyclonic separator (10). The separation device (14) has a guide member (17) that comprises a leading end (17A), a trailing end (17B), and a guide surface (17C). The guide surface guides debris entrained in an airflow in the cyclone chamber in a helical path about an axis (X-X) of the separation device (14) and into the collection chamber (16). The guide surface extends about the axis of the separation device (14) through an angle of less than 360 degrees for allowing debris in the cyclone chamber (15) to also pass into the collection chamber (16) from the cyclone chamber in an axial direction. The leading end (17A) of the guide member (17) is at an angle (a) between 30 degrees and 60 degrees towards the cyclone chamber (15) with respect to the axis (X-X) of the separation device (14) to promote a helical flow of air and debris flowing over the guide surface.

Abstract: The present application relates to a vacuum cleaner head (2). The vacuum cleaner head (2) has a base (10) and a suction opening (8) in the base (10). An array (35) of flexible flaps (40) protrude from the base (10). The flexible flaps (40) are configured to act on a surface to be cleaned. The flexible flaps (40) are spaced from each other to allow the passage of detritus therebetween in a predefined arrangement. The predefined arrangement of the flexible flaps (40) is configured to promote a non-linear flow path through the array (35) of flexible flaps (40) between an end of the base (15, 16) and the suction opening (8). A gap (39) between first and second rows (36, 37) of flaps (40) is substantially equal to or greater than a space (43) between adjacent flexible flaps (40) in each of the first and second rows. The present application also relates to a vacuum cleaner (1) comprising a vacuum cleaner head (2).
