Abstract: 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.

Abstract: Apparatus and method for receiving and holding debris in a collection chamber of a vacuum cleaner. A cleaning head is coupled to a body of the vacuum cleaner via one or more suspension elements that comply to horizontal oscillations of the cleaning head imparted by an offset bearing of a vertical gear drive driven by a motor mounted to the body. A vacuum source draws air in from a suction nozzle at a forward underside portion of the cleaning head adjacent to a cleaning pad, and the air travels through an air filter disposed between the vacuum source and the collection chamber. In some embodiments, the air filter comprises one or more pleats adjacent to the vacuum source.

Abstract: 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, an internal valve prevents debris from leaving the collection chamber through the inlet opening. The internal valve is movable from a first sealed position, in which the internal valve covers the chamber inlet opening, to a second unsealed position in which the internal valve does not cover the chamber inlet opening.
