A cleaner apparatus including a filler configured to reduce static electricity is provided. The cleaner apparatus includes a main body, a dust container detachably coupled to the main body, an extension tube having an end detachably coupled to the main body, and a suction head detachably coupled to another end of the extension tube, wherein the dust container includes a first filler having a charge mobility of 16,000 to 200,000 cm.sup.2/Vs and an aspect ratio of 1:1,500 to 1:8,500.

A suction device with at least one blower with a motor, at least one temperature sensor, and at least one control device. A method for operating a suction device as well as a computer program product is also provided. The suction device, as well as a method for operating a suction device and a computer program product, which prevents overheating of components within the suction device and simultaneously ensures energy efficiency, are realized in that the control device is designed and arranged to throttle or increase, at least temporarily, one operational parameter of the motor, depending on a comparison of a temperature value of the temperature sensor with at least one temperature threshold value.

A hand vacuum cleaner has an information display device provided on a rear wall of the rear end of the hand vacuum cleaner.

The present disclosure provides a floor cleaner that includes a replaceable component, such as a brushroll or a filter. The floor cleaner has a detection mechanism comprising a magnet on the replaceable component and a Hall Effect sensor positioned to detect the permanent magnet when the replaceable component is correctly installed on the floor cleaner. Operation of one or more electrically-powered components of the floor cleaner is prevented when the permanent magnet is not detected by the Hall Effect sensor.

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.

An autonomous mobile cleaning robot can include an outer shell and a bumper. The outer shell can include a rim extending around at least a portion of a periphery of the outer shell and can include a first feature connected to the rim. The bumper can be connected to the outer shell and can movable with respect to the outer shell when the bumper is connected to the outer shell. The bumper can include a second feature connected to the inner surface.

The present invention relates to a cleaning appliance and a method for a cleaning appliance. In particular, a cleaning appliance is disclosed, comprising: a housing, comprising an opening facing toward a surface to be swept; a sweeping brush, having a connection part by means of which the sweeping brush is mounted in the housing, and being capable of rotating about a rotation axis by receiving a driving force, so as to perform a sweeping operation; and a toothed structure arranged close to an end of the sweeping brush, the toothed structure being provided between the housing and the sweeping brush and comprising multiple teeth, the multiple teeth extending from one of the housing and the sweeping brush toward the other of the housing and the sweeping brush. The cleaning appliance of the present invention is at least able to prevent or at least reduce the entry of foreign matter into a gap, as well as promptly trigger protection measures when necessary to remind a user to deal with the problem, in order to avoid failure due to melting of the housing and sweeping brush in a connection region.

A working trolley with built-in dust suction system includes a dust suction system and a trolley. Through directly assembling the dust suction system with the trolley, useless structures in the dust suction system is eliminated, so that the dust suction system can be assembled with the trolley with a more simplified structure. Through directly assembling the dust suction system with the trolley, the trolley breaks the old and stereotyped way of using, and the trolley is no longer just a carrying tool of a vacuum cleaner, thereby greatly increasing the effectiveness of usage of the trolley. On the other hand, the present invention enables a dust storage bucket of the dust suction system to have a feature of being independently dismountable, so that an operator does not need to dismount other components when replacing the dust storage bucket, thereby facilitating operation for the operator.

A cleaner includes: a main body; a connection pipe having one end connectible to the main body; and a brush head connectible to an other end of the connection pipe The brush head includes: an suction inlet formed therein, a drum brush detachably installed inside the brush head, a driver configured to drive the drum brush; a suction chamber formed inside the brush head and communicating with the suction inlet; a first cover covering one side of the brush head, the first cover having an inlet formed therein and through which air enters inside of the drum brush is formed in the first cover; and a second cover covering an other side of the brush head to seal inside of the brush head, the second cover having an outlet duct formed therein through which air cooled the inside of the drum brush is discharged to the suction chamber.

A vacuum cleaner includes a main body portion, a secondary battery, an electric blower, a handle and a conductive member. The secondary battery is disposed in the main body portion. The electric blower operates by electric power supply from the secondary battery. The handle is one which a user contacts when the vacuum cleaner is used. At least a part of the conductive member is disposed at the handle and conducts static electricity generated due to operation of the electric blower.
