摘要： 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.

摘要： 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.

摘要： A vacuum cleaner having a housing and a suction inlet thereon, the cleaner comprising a suction source in fluid communication with the suction inlet to produce a working airflow therethrough and a dirt container in fluid communication with the suction inlet and suction source. The housing further comprises a body defined by a central portion and a pair of extension arms that extend laterally outwardly from the central portion, wherein each extension comprises a mount, which receives a rotatable agitator thereon. A drive assembly is configured to counter-rotate each agitator with respect to the other agitator, and wherein the suction inlet is positioned on the housing rearward of, and between, each of the axes of rotation of each agitator. The counter-rotating agitators are operable to cooperate with the suction source to direct dust and debris outside the periphery of the housing along a converging debris path, towards the suction inlet.

摘要： A cleaning system. The system has a floor cleaning device, disposable floor sheet removably attachable to the device pad, and a rotatable beater bar. The device has a single wheel, and moves on the target surface by rolling action of the wheel and gliding of the floor sheet. This arrangement, not having multiple wheels, provides enhanced maneuverability, and improves cleaning performance. The cleaning system may be used to clean hard surfaces, such as a floor.
