A filter device for a vacuum cleaner having a turbine device and a motor. The vacuum cleaner includes two chambers and filter elements of the filter device are dedusted by an abrupt change in position of a dividing element in the chambers. Since, when one of the two chambers is being dedusted, the suction operation of the vacuum cleaner can be maintained through the other chamber, the filter dedusting can advantageously take place during continued suction operation of the vacuum cleaner. A method for dedusting a filter device in a vacuum cleaner, wherein, as a result of a valve being actuated, an air volume is driven out of one of the two chambers so that a dividing element is advantageously made to change position, and this can result in a backflushing pulse and mechanical shaking of the filter element, and dedusting of the filter device.

A portable dust extractor is disclosed and includes a housing, a collection chamber in the housing, a first filter chamber in the housing and in fluid communication with the collection chamber, wherein a first filter is disposed within the first filter chamber, a second filter chamber in the housing and in fluid communication with the collection chamber, wherein a second filter is disposed within the second filter chamber, and a manifold system adjacent to the first filter chamber and the second filter chamber, wherein the manifold system is operable to permit air flow through the first filter and the second filter in a filter direction and operable to permit air flow through the one of the first filter and the second filter in a filter direction while permitting air flow through the other of the first filter and the second filter in a debris removal direction.

A vacuum cleaner system comprising a motor-impeller assembly, a power source, and a hose. The motor-impeller assembly is configured to generate fluid flow, the fluid flow passing through a hose inlet. The power source is configured to supply power to the motor-impeller assembly. The hose includes a proximal hose end configured to be coupled to the hose inlet, a distal hose end spaced from the proximal hose end, and a hose body. The hose body is coupled to the proximal hose end and the distal hose end. The hose body has an inner surface through which fluid flow passes, and an outer surface open to the surroundings of the hose. The hose further includes a layer of anti-static material applied to either the inner surface of the hose body or the outer surface of the hose body.

A portable surface cleaning apparatus for a floor surface includes a main housing assembly adapted to be hand carried by a user, the main housing assembly carrying a fluid delivery system adapted for storing cleaning fluid and delivering the cleaning fluid to the surface to be cleaned, and a fluid recovery system adapted for removing the cleaning fluid and debris from the surface to be cleaned and storing the cleaning fluid and debris that was recovered, the main housing assembly comprising a base housing, a supply tank received on the main housing assembly, a recovery tank received on the main housing assembly separately from the supply tank.

A vacuum cleaner has a portable cleaning unit that is removably mounted to the surface cleaning head. The vacuum cleaner is operable in a floor cleaning configuration in which the portable cleaning unit is mounted to the surface cleaning head and is part of the air flow path through the vacuum cleaner. The portable cleaning unit is also useable in a portable cleaning configuration in which the portable cleaning unit is removed from the surface cleaning head.

A dust removal device includes a suction head and at least one filter element. The at least one filter element is disposed obliquely within the dust removal device such that floating mounting of the suction head is maintained by automatic, vacuum-induced suction on the at least one filter element. A method for changing a filter element in a dust removal device includes replacing a filter element from above.

A reconfigurable upright surface cleaning apparatus comprises a surface cleaning head and a support structure moveably mounted to the surface cleaning head. The support structure comprises a lower portion having a lower longitudinal axis and an upper portion having an upper longitudinal axis, the lower portion having a lower end moveably coupled to the surface cleaning head and an upper end that is rotatably coupled to the upper portion about a rotational axis that is generally transverse to the forward direction, wherein, the support structure is reconfigurable between a first configuration in which the lower portion and the upper portion are generally aligned with each other and an operating position in which the lower portion is rotated rearward with respect to the surface cleaning head and the upper portion is rotated in the forward direction with respect to the lower portion. A hand vacuum cleaner comprising a suction motor and an air treatment member is removably mounted to the support structure. An air flow path comprises a flexible hose.

A vacuum cleaner, comprising: a housing; a motor unit provided in the housing and used for generating suction force; a dust cup provided on the housing and used for collecting sucked particles, the dust cup comprising a suction inlet; a battery for supplying power to the vacuum cleaner; a handle located on the housing; and a suction pipe unit having a storage state, wherein under the storage state, the suction pipe unit extends from the suction inlet on one side of the dust cup, across the handle, and to the other side of the dust cup along the length direction of the handle. The motor unit and the dust cup are located on the same straight line direction; the battery is provided on a side of the housing. The layout of the whole machine components of the present vacuum cleaner is optimized, and the performance of the vacuum cleaner is guaranteed under the premise of miniaturization.

A wet/dry vacuum (1) having a bottom vertical discharge (13) located on a collection tank (2) and an elevated rolling stand (14) that allows the wet/dry vacuum and collection tank to be rolled over a bucket or toilet and emptied of any collected liquids. A strainer 13 and hinged attachment to the stand allows a user to easily empty hard debris from the wet/dry vacuum by simply tipping the collection tank over from its elevated position into a trash can.

A dust collector has a well-balanced weight. The dust collector includes a body housing, a motor located inside the body housing, a fan rotatable by the motor, and a battery mount located inside the body housing and frontward from the motor.
