A household appliance has a device housing, a blower arranged in the device housing, an outlet opening formed in a direction of flow behind the blower in the device housing, a flow channel that connects the outlet opening with the blower in terms of flow, and a sound attenuator allocated to the flow channel for attenuating sound arising from the operation of the household appliance. The sound attenuator has sound-absorbing wall elements that have a wall surface that is curved in relation to a direction of a longitudinal extension of the flow channel, a support body for receiving the sound-absorbing wall elements, and a sound-reducing wall with a wall plane oriented parallel to the flow path. The sound attenuator is modular in design, formed of the support body, wall elements and sound-reducing wall, and is installed as a whole into the device housing between the blower and outlet opening.

The invention relates to a floor vacuum cleaner comprising a dust collector arrangement mounted on rollers and/or runners, a suction hose, a suction tube and a floor nozzle, wherein the floor nozzle is fluidically connected to the dust collector arrangement via the suction tube and the suction hose, also comprising a motorized fan unit for suctioning an air stream through the floor nozzle, wherein the motorized fan unit is arranged between the floor nozzle and the suction tube such that an air stream suctioned in through the floor nozzle flows through the motorized fan unit and into the suction tube.

The present invention relates to an autonomously operable vacuum cleaner that has a modular design. The vacuum cleaner in this respect comprises a cleaning head module as well as a separate canister module. The cleaning head module and the canister module are in this respect connected to one another via a hose so that dust sucked in via the cleaning head module can be conveyed into the canister module.

A dust cup assembly (100) and a handheld cleaner (1000) having the same are provided. The dust cup assembly (100) includes: a cup casing (1); a device housing (2) configured as a tube shape and disposed in the cup casing (1), wherein an outer end face of the device housing (2) at an axial side thereof abuts against or extends beyond a partial inner surface of the cup casing (1), and a dust removal chamber (A1) is defined between an inner surface of the cup casing (1) and an outer peripheral surface of the device housing (2) and surrounds the device housing (2) along a circumferential direction of the device housing (2); and a negative pressure device (3) located within the device housing (2) and enabling dusty air to enter the dust removal chamber (A1) for dust and air separation.

An upright vacuum cleaner has a handle by which it can be manoeuvred across a floor in a floor cleaning mode, the handle being part of a releasable suction wand which can be used in an above-floor cleaning mode. The suction wand has a first section which comprises the handle, a second section, and a third section which comprises a suction nozzle. The first section is movable relative to the second section between floor cleaning and above-floor cleaning positions. The third section is extendable and retractable relative to the second section. The suction wand has a linkage which is configured to couple movement of the first section towards one of said positions, and extension or retraction of the third section.

The invention relates to a floor vacuum cleaner comprising a dust collector arrangement mounted on rollers and/or runners, a suction hose, a suction tube, and a floor nozzle, wherein the floor nozzle is fluidically connected to the dust collector arrangement via the suction tube and the suction hose, wherein the dust collector arrangement comprises a dust separator, wherein the dust collector arrangement comprises a motorized fan unit for suctioning an air stream through the floor nozzle, wherein the motorized fan unit is arranged so that an air stream suctioned in through the floor nozzle, the suction tube, and the suction hose flows through the motorized fan unit and into the dust separator, wherein the dust collector arrangement has a housing and the motorized fan unit is mounted on or in the housing, wherein the dust separator is mounted in the housing.

In order to accomplish a solution task of the present disclosure, a cleaner hand according to an embodiment of the present disclosure may include a pipe configured to transfer at least one of air, dust, and foreign matter to a drive unit that generates a suction force, a grip portion connected to the pipe, and formed to be gripped by a user, a sensor unit disposed in the grip portion to sense information related to whether or not the grip portion is gripped by the user, and a controller configured to control the drive unit based on the sensed information.
