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.

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.

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.

The present disclosure provides a charging mount and a vacuum cleaner assembly including the charging mount and a vacuum cleaner. The support member is provided with the curved plate clamped by the claw of the fastening head, achieving a quick fixing of the vacuum cleaner to the charging mount. Once the fastening head is engaged with the curved plate, the first electrical contact can be accurately contact the second electrical contact to ensure a stable electrical connection, resulting in stable charging. The first baseplate is provided with a plurality of securing columns for fixing and mounting spare accessories, resulting in convenience for arrangement. The seating groove and the limiting plate of the second baseplate as well as the limiting block of the first baseplate contribute to secure and limit the position of the brush head portion, resulting a stable placement of the vacuum cleaner on the charging mount.

A telescopic conductive tube is provided, including a conductive assembly. The conductive assembly includes an isolating guide, an isolating restraining tube, a rail, a wire, a guiding rod and a conductive spring. The conductive spring is sleeved on the guiding rod and electrically connects with the wire. The guiding rod and the conductive spring are accommodated within the isolating restraining tube. The isolating restraining tube is accommodated within the isolating guide. The wire is accommodated within the rail. The isolating restraining tube has one end inserted into the rail. The rail is slidable relative to the isolating guide. When sliding into the isolating guide, the rail slides along an outer wall of the isolating restraining tube, and the conductive spring is compressed by a bottom of the rail.

An artificial intelligence cleaner may determine a length of a head from user cleaning information including a height of a user, a pressure sensing value applied to the head and a head angle between the head and the ground using a head length calculation model and control a head motor to have the determined length of the head.

A tube arrangement is described, said arrangement comprising: an inner tube and an outer tube telescopically slidable relative to each other; wherein the inner tube comprises, on an outer surface thereof, a longitudinal groove and a plurality of deformations having a predetermined shape; a sleeve fitted into the outer tube, at one of its ends; a fastening device configured to prevent sliding of the inner tube with respect to the outer tube, when said fastening device is at least partially engaged in one of said deformations; a slider and elastic means, wherein the slider cooperates with the fastening device under the action of the elastic means; and an actuating device operatively connected to the slider; wherein the longitudinal groove forms, at one end of the inner tube, a slide inclined towards the longitudinal axis of the inner tube for separating the inner tube from the outer tube.

A vacuum cleaner includes a cleaner main body, a suction device, a suction motor, and a dust container. The dust container includes a dust collection body configured to contain dust, an opening/closing portion rotatably coupled to the dust collection body and configured to rotate to thereby open and close at least a portion of the dust collection body, and an operation portion connected to the dust collection body and configured to rotate in both a first direction and a second direction opposite the first direction. The opening/closing portion is configured to rotate based on the operation portion rotating in the first direction, and configured to rotate based on the operation portion rotating in the second direction.

A cleaner that includes: a main body; a suction assembly; and a coupling hose, wherein the main body includes: an air suctioning device, a case, a driving motor that is coupled to a first surface of the case and that is configured to generate driving force, a traveling wheel that is coupled to the first surface of the case and that is configured to rotate based on driving force generated by the driving motor, a motor cover that is configured to cover the driving motor such that the driving motor is located in a space between the first surface of the case and the motor cover, a rotating shaft that is coupled to the driving motor and that is configured to transfer driving force generated by the driving motor to the traveling wheel, and a coupling unit that couples the rotating shaft to the traveling wheel is disclosed.

Disclosed are a dirt suction guide device and a cleaner comprising the same. The disclosed cleaner comprises: a cleaner body for generating a suction force; a flexible hose connected to the cleaner body; an extension tube connected to the flexible hose; and a dirt suction guide device separately coupled to the extension tube, wherein the dirt suction guide device comprises a body, a movable portion, which is connected to one side of the body, and which is coupled to be able to slide with regard to the body, and a connecting portion, which is connected to the other side of the body, and which connects the body to the extension tube, and the body is hinge-coupled such that the same can selectively maintain and change an angle with regard to the extension tube.
