A replacement head for a vacuum device includes a plastic tray, a filter and a pad. The plastic tray includes a dust chamber and opening allows air, dust and debris to be drawn into the dust chamber during use. The pad is attached to the lower side of the plastic tray and is in contact with the floor during cleaning. The filter is connected to the plastic tray such that the filter substantially covers a top opening in the dust chamber. The filter is preferably made of a non-woven material with a basis weight between about 20 and 70 gsm, and has a thickness less than about 1.0 mm.

A replacement head for a vacuum device includes a plastic tray, a filter and a pad. The plastic tray includes a dust chamber that has a sealing surface and at least one opening. The opening is provided to allow air, dust and debris to be drawn into the dust chamber during use. The sealing surface defines a sealing surface plane and the opening defines an opening place. The relative angle between the sealing surface plane and the opening plane is preferably between about 20 degrees and +150 degrees. The pad is attached to the lower side of the plastic tray and is in contact with the floor during cleaning. The filter is connected to the plastic tray such that the filter substantially covers a top opening in the dust chamber.

Apparatus and method for adjusting a height of a suction chamber of a vacuum cleaner relative to a target cleaning surface. The vacuum cleaner includes a compressible cleaning sheet, such that as a user selectively executes different motions and/or applies different forces to a handle of the vacuum cleaner, the cleaning sheet compresses or uncompresses, dynamically adjusting the height of the suction chamber.

Methods and apparatus for cleaning a surface with a cleaning device having a body with a handle, a connector, and one or more cleaning heads that are removably attached to the cleaning device are disclosed. Each cleaning head includes a lower surface arranged to contact a surface to be cleaned, a dirt collection chamber, and a pocket arranged to receive an insert of the connector to attach the cleaning head to the cleaning device. In some embodiments, the connector insert is pivotally connected to the connector. In some embodiments, the cleaning head includes a support structure and a cleaning sheet, with the pocket being formed between the support structure and the cleaning sheet.

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.
