A vacuum attachment for a vacuum tube of a vacuum for a non-destructive screening of an object and/or a living creature. The vacuum attachment includes a suction tube, a collection unit, and an adapter unit. The suction tube has a first end and a second end. The first end is arranged opposite to the second end. A suction opening is arranged at the first end. The collection unit for the non-destructive screening is arranged in the suction tube downstream of the suction opening in a suction direction. The collection unit has at least one opening for a flow of a suction air stream, and an air-permeable impact protection material arranged upstream of the at least one opening in the suction direction. The adapter unit is arranged at the second end of the suction tube. The adapter unit connects to the vacuum tube of the vacuum.

A cleaner includes: a suction motor that generates suction force; a dust separation unit that separates dust from air sucked by the suction force; a motor housing that covers the suction motor; a flow guide that surrounds an outer side of the motor housing and guides air discharged from the dust separation unit to the suction motor; and a body that forms an external appearance by surrounding the flow guide and guides air discharged from the suction motor together with the flow guide.

In order to make it possible to remove dust produced in a heating furnace 10 more efficiently than ever before, the present invention is adapted to include: a dust discharge passage L that communicates with the inside of the heating furnace 10 and is for discharging dust produced by heating a sample X; a dust accommodating part 30 that accommodates the dust discharged from the dust discharge passage L; and a negative pressure generating mechanism 90 that is provided in the dust discharge passage L and generates negative pressure in the dust discharge passage, in which the negative pressure generated by the negative pressure generating mechanism 90 guides the dust from the heating furnace 10 to the dust discharge passage L.

Provided is a cleaning device comprising: a camera unit for capturing an image; a cleaning unit for cleaning; an air purification unit for purifying air; a driving unit for moving the cleaning device; and a processor for controlling the camera unit, the cleaning unit, the air purification unit and the driving unit, wherein the processor detects a user by using the camera unit, cleans by moving the cleaning device to a position exceeding a first threshold distance from the detected user when the cleaning device is in a cleaning mode, and purifies the air by moving the cleaning device to a position within a second threshold distance from the detected user when the cleaning device is in an air purification mode.

An electric vacuum cleaning apparatus including an autonomous robotic vacuum cleaner that autonomously moves between surfaces to be cleaned and collects dust and a station fluidly connectable to the autonomous robotic vacuum cleaner. The autonomous robotic vacuum cleaner includes: a container body accumulating collected dust, the container body including: a bottom wall including a disposal port; and a disposal lid opening and closing the disposal port. The station unit includes: a dust transfer pipe connected to the disposal port; a secondary dust container accumulating dust; and a secondary electric blower that generates negative suction pressure in the dust transfer pipe via the secondary dust container. At least one irregularly shaped ventilation groove that causes air to flow below the dust within the container body by the negative pressure generated by the secondary electric blower is provided to the inner surface of the bottom wall of the container body.

A vacuum cleaning apparatus including a cyclonic separating apparatus having a first cyclonic separator, a second cyclonic separator downstream, a first dirt collector for collecting dirt from the first cyclonic separator comprising an end wall, and a second dirt collector for collecting dirt from the second cyclonic separator comprising an outer wall and at least a portion of the end wall. The first dirt collector and the outer wall of the second dirt collector are movable between a closed configuration in which the end wall abuts the outer wall and an open configuration in which the end wall is spaced from the outer wall for removing dirt from the second collector. The apparatus comprises a detent mechanism for permitting movement of the first dirt collector and the outer wall of the second dirt collector from the closed to the open configurations and to prevent movement into the open configuration.

A handheld vacuum cleaner is provided with a hand-carriable body housing the components of a vacuum collection system, which can include a working air path through the body from an air inlet to an air outlet. An air deflector is positioned in opposition to the air inlet and directs a working airstream from the air inlet downwardly within a debris removal assembly.

A low profile upright surface cleaning apparatus has an upright section which includes an air treatment member and a dirt collection region that is positioned laterally from the air treatment member wherein at least 60% of the volume is positioned laterally from the cyclone and/or on only one side of the air treatment member.
