A vacuum cleaner includes a body, an electrically-driven suction unit, a device for collecting dust, a suction channel, a nozzle communicating with the body through the suction channel, an intake device for ensuring an additional portion of air fed into the suction channel and being adjustable between an opened and a closed state, and a control unit for controlling the suction unit. The intake device is bi-directionally electrically connected to the control unit, so that transmission of data or signals between the intake device and the control unit is enabled. The control unit is configured to generate a signal for controlling the intake device in the event of detecting the cleaning start signal or the cleaning end signal. A method for operating a vacuum cleaner is also provided.

A manure collecting vehicle includes: a manure collector having a manure collection port and at least one powered rotational manure conveyer to convey manure to the manure collection port as the vehicle drives through the manure; a manure holding tank in manure communication with the manure collection port, collected manure passing through the manure collection port into the manure holding tank as the vehicle drives through the manure; and, an air system to create an air pressure differential between inside the manure holding tank and outside the manure holding tank when the vehicle is driving through the manure to be collected so that the collected manure passes from the manure collection port into the manure holding tank under influence of the air differential.

Devices for collecting patient excretions utilize existing suction sources and facilitate the cleaning of bedding and/or a patient. Patient excretion collection devices comprise a collection reservoir and a collection wand which are attached to an existing source of suction.

A vacuum cleaner and filter cleaning system includes a filter cleaning mechanism which allows the filter to be cleaned without removal from the vacuum. Operation of the filter cleaning mechanism both flows air backwards through the filter and strikes the filter to more effectively clean the vacuum filter. The vacuum allows for filter cleaning and debris disposal without significant interruption of the use of the vacuum cleaner.

Disclosed is a robot cleaner which adjusts a suction area of air suctioned into a suction port through a shutter and a shutter driving device configured to operate the shutter, so that a flow rate of air is adjusted, thus more effectively suctioning dust in the air by using a fan motor having a fixed capacity.

Disclosed is a vacuum cleaner that opens or closes a hole formed in a suction portion according to a state of a surface to be cleaned, thereby efficiently cleaning. A vacuum cleaner includes a suction portion configured to suck foreign materials on a surface to be cleaned. The suction portion includes a case having an air hole formed in a flow path, a frame configured to be accommodated in the case and open or close the air hole, and a button configured to be mounted on the case and be operated to move the frame.

A vacuum cleaner basically includes a motor, first and second inlets and a cover. The motor is configured to create flow through a suction path. The first inlet and the second inlet are disposed in the housing in fluid communication with the suction path. A cover is pivotably disposed in the second inlet. The cover is movable between a first position in which the second inlet is substantially covered to substantially prevent fluid from flowing through the second inlet and a second position in which fluid is allowed to flow through the second inlet.

A vacuum cleaner includes a suction nozzle defining a nozzle inlet, a manual nozzle height adjustment assembly for adjusting the height of the nozzle inlet relative to a surface to be cleaned, and a bleed valve fluidly connected to a working air path of the vacuum cleaner to selectively open to reduce suction at the nozzle inlet. The bleed valve is incorporated with the nozzle height adjustment assembly such that movement of the nozzle height adjustment assembly between different height settings will automatically open or close the bleed valve.

The present invention relates to a flow structure of a companion animal duct collector, and more particularly, to a flow structure of a companion animal duct collector including a main body part that includes an inner case through which air or hair of a companion animal is introduced and an outer case surrounding front and rear surfaces of the inner case and discharging air moving through the inner case to the outside, a suction fan unit that has a motor fan inside the inner case, and a suction grill unit that includes a suction grill coupled to one side of the outer case and sucking in external air by the operation of the suction fan unit, whereby air is collected to the other side of the main body part to form a low pressure part, thereby forming an additional air flow by the operation of the suction fan unit.

A floor vacuum cleaner for cleaning a floor surface has a chassis with a chassis frame for traveling over the floor surface. A suction nozzle aspirates an airflow in the region of the floor surface. The suction nozzle is mounted relative to the chassis in the direction of travel to the front left and front right in each case by way of a mounting arrangement formed of a journal and a guide. The mounting arrangement allows a tilting of the suction nozzle about the journals, a rotation of the suction nozzle about a longitudinal axis, and a vertical movement of the suction nozzle, but a movement of the suction nozzle in the longitudinal direction of the chassis is prevented.
