This invention relates to a suction head (10) for a vacuum cleaner and method of operation. The suction head (10) has a bottom surface (26) and one or more floor-engaging parts (36) adjacent to the bottom surface (26), an opening (24) in the bottom surface (26) and a rotatable brush (30) located at the opening (24). The suction head (10) has a front end (16) and a rear end (18), the front end (16) having a recess (22) in communication with the opening (24). A movable strip (42) is located in the recess (22), the movable strip (42) being movable between a first position and a second position, the bottom edge of the movable strip 4(2) being closer to the plane of the floor-engaging parts (36) in its first position than in its second position. At least one first element (54) is connected to the movable strip (42) and is able to project to the plane of the floor-engaging parts (36). At least one second element (56) is also connected to the movable strip (42), the second element(s) (56) being configured differently to the first element(s) (54), the second element(s) (56) being able to project to the plane of the floor-engaging parts (36) and being configured to move the movable strip (42) to a third position in use. The bottom edge of the movable strip (42) is closer to the plane of the floor-engaging parts (36) in its second position than in its third position. According to the method of operation, the movable strip (42) moves to its first position during backwards movement of the suction head (10) and to its third position during forwards movement of the suction head (10), the movable strip (42) moving to its third position in two stages.

The present invention relates to a vacuum cleaner robot comprising a floor nozzle supported on wheels and a dust collection unit, wherein the floor nozzle comprises a driving device for driving at least one of the wheels of the floor nozzle, wherein one of the wheels, a plurality of or all of the wheels of the floor nozzle are omnidirectional wheels, wherein the floor nozzle comprises a base plate with a base surface, which, when the vacuum cleaner robot is in operation, faces the surface to be cleaned, the base plate having provided therein an air flow channel, which extends parallel to the base surface and through which air to be cleaned enters the floor nozzle, and wherein the floor nozzle comprises a rotating means for rotating the air flow channel about an axis perpendicular to the base surface.

Apparatus and method for receiving and holding debris in a collection chamber of a vacuum cleaner. The collection chamber has an inlet opening through which debris-entrained air enters the collection chamber. When the vacuum cleaner is off, the cover prevents debris from leaving the collection chamber through the inlet opening. The wall of the collection chamber moves when negative pressure is applied to the collection chamber, and the wall movement moves the cover from the inlet opening, allowing the debris-entrained air to enter the collection chamber. In some embodiments, the moving part of the wall is an air filter.

A nozzle includes: a housing having a chamber formed in the housing and a front opening formed on a front side of the housing; a rotation cleaning part accommodated in the chamber and to clean a floor; a partition member provided in the chamber to partition the chamber into two areas and of which at least a portion is in contact with the rotation cleaning part; a driving unit to rotate the rotation cleaning part; and a connection tube connected to the housing and configured to transfer air introduced through the front opening to a dust container of the cleaner, wherein a lower passage formed below the rotation cleaning part and an upper passage formed above the rotation cleaning part are provided in the chamber, and a portion of the partition member is recessed to define the upper passages.

A vacuum tool configured to be removably coupled to hose or wand of a vacuum includes a body including a first end, a second end, and a first longitudinal axis extending between the first end and the second end. The vacuum tool also includes a head coupled to the first end of the body, a connection portion coupled to the second end of the body and configured to couple the body to a hose or wand of a vacuum cleaner, and a brush coupled to the head. The brush includes an elongate support defining a second axis perpendicular to the longitudinal axis of the body and configured to couple the brush to the head, and a plurality of bristles positioned on the elongate support.

A vacuum-cleaner nozzle has a housing formed with a downwardly open suction mouth on a lower face of the housing and having a front mouth edge and a rear mouth edge. A suction fitting on a rear end of the housing and opening into the housing serves for drawing air in through the mouth. A floor-engaging support rearward of the rear mouth edge is vertically displaceable relative to the housing between upper and lower positions. A spring biases the support into the lower position.

An extraction head for a cleaning machine is disclosed for traveling along a cleaning path on a variable-height floor. The extraction head comprises a body including a floor-facing surface and an extraction aperture disposed in the floor-facing surface. The extraction head comprises a vacuum outlet in fluid communication with the extraction aperture. The extraction head comprises an adjustable-height brush positioned in front of the extraction head body along the cleaning path. The adjustable-height brush is configured to translocate upwardly and downwardly as the extraction head moves along the cleaning path on the variable-height floor. The adjustable-height brush may comprise a proximal end and a distal end opposite the proximal end. The proximal and distal ends may be configured to translocate upwardly and downwardly relative to each other as the extraction head moves along the cleaning path on the variable-height floor.

A floor vacuum cleaner for cleaning a floor surface has a chassis with a chassis frame for traveling over the floor surface. A suction nozzle aspirates an airflow in the region of the floor surface. The suction nozzle is mounted relative to the chassis in the direction of travel to the front left and front right in each case by way of a mounting arrangement formed of a journal and a guide. The mounting arrangement allows a tilting of the suction nozzle about the journals, a rotation of the suction nozzle about a longitudinal axis, and a vertical movement of the suction nozzle, but a movement of the suction nozzle in the longitudinal direction of the chassis is prevented.
