A robotic vacuum cleaner docking station has a mechanical transfer mechanism that is used to transfer dirt from a robotic vacuum cleaner to a docking station.

The present disclosure includes a vacuum stall canopy assembly for a car wash system having a first post assembly having a base leg permanently attached to the ground, a beam attached to the top of the first post assembly, a roof assembly disposed on an upper portion of the beam, a debris separator disposed on the beam, the debris separator having a first side and a second side, a main airline fluidly connected to the debris separator and configured to be connected to a source of vacuum suction, a first hose on the first side of the debris separator, and having a first nozzle on a distal end of the hose from the debris separator, and a second hose on the second side of the debris separator, and having a second nozzle on a distal end of the hose from the debris separator.

A method of cleaning a floor comprises providing an autonomous surface cleaning apparatus, positioning a plurality of docking stations at different locations on the floor wherein a first docking station has an absence of an evacuation mechanism and actuating the autonomous surface cleaning apparatus whereby the autonomous surface cleaning apparatus travels across the floor to clean at least a portion of the floor and recharges at the first docking station.

A cleaner includes a dust bin, a motor housing disposed above and coupled to the dust bin, a handle coupled to the motor housing, a cyclone part disposed in the dust bin and configured to separate dust from air, a filter disposed in the dust bin and configured to filter air having separated the dust through the cyclone part, and a compression part configured to compress the dust in the dust bin. The compression part includes an operating part disposed in the motor housing and configured to move in a space between an outer portion of the filter part and an inner circumferential surface of the dust bin, a manipulation part disposed outside the motor housing and configured to be manipulated to move the operating part, and a transmission part that is disposed in the motor housing and connects the operating part and the manipulation part.

A trap for use with a vacuum cleaner includes a trap body formed in a substantially cylindrical shape. The trap body includes a suction opening formed at one axial end to suck in a target to be trapped and an insertion opening formed at the other end to be inserted into a vacuum cleaner. An adhesive is provided on at least a portion of an inner surface of the trap body. The trap for use with a vacuum cleaner includes a net portion. The net portion blocks a plane orthogonal to an axial direction of the trap body. The net portion includes a net formed in at least a portion to transmit air sucked in through the suction opening. The trap body includes a protrusion formed on at least a portion in a circumferential direction of an outer surface thereof to protrude outward.

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 surface cleaning apparatus includes a base assembly with a suction nozzle and at least one wheel. A hand-held portion has a hand grip, a recovery container, and a suction source in fluid communication with the suction nozzle and the recovery container and configured for generating a working airstream. A wand is operably coupled between the base assembly and the hand-held portion and defines at least a portion of a working air path extending from the suction nozzle to an air outlet in the hand-held portion and including the suction source.

A modular blast gate for a dust collection system. The blast gate includes first and second regions. The first region has a first configuration and enables securement of a duct of the dust collection system to the first region via a first connector mechanism. The second region has a second configuration different from the first configuration and enables securement of the duct to the second region via a second connector mechanism different from the first connector mechanism. The blast gate is usable to connect differently configured ducts, hoses, or pipes to equipment that generates particulate material. The blast gate is mountable to the equipment or a support surface. Two of the modular blast gates may be joined to one another to enable two ducts to be connected together.

A vacuum hose holding apparatus that is configured to be releasably secured to a container proximate an upper edge thereof wherein the present invention is operable to have a vacuum hose releasably secured thereto and maintain position thereof during discharge of debris into the container. The present invention includes a frame wherein the frame includes a central cradle member. The central cradle member is secured to the container with a first securing member and a second securing member. A first hose support section extends downward from the central cradle member and includes a hose retention member operably coupled thereto. A second hose support section is secured to the upper end of the central cradle member and extends outward therefrom. The second hose support section includes a hose engagement member that is arcuate in shape. The central cradle member further includes a hose retention member.

The present invention relates to vacuum cleaners with steam functionality (steam and vacuum cleaners), preferably to canister steam and vacuum cleaners, comprising a suction hose and a steam hose for respectively suctioning dirt and conveying steam, wherein the steam hose is external to the suction hose and comprises, at each end, a detachable connector, preferably a rapid-fitting detachable connector, for optionally detaching the steam hose when using only the vacuum cleaning functionality.
