A suction device with at least one fan for generating a suction air stream in a suction channel, at least one filter device for receiving suction material, at least one pressure measuring system and at least one control device, wherein the suction device is configured for coupling to a plurality of attachments on the suction channel, as well as a method for determining the filling level for a filter device of the suction device. The suction device and the method for determining the filling level ensures the most precise display possible of the filling level and also is simultaneously realizable in a cost-effective manner, in that the control device is configured and arranged for determining the filling level using at least one pressure measurement value and characteristic data, as well as for selecting the characteristic data used for the determination depending on the attachment connected to the suction device.

A cyclonic, dust-collecting unit includes: one or more air swirling members, which swirl(s) air; a dust cap, into which air that has passed through the swirling member(s) flows; and a filter unit, through which air that flows out of the dust cap passes. The filter unit includes: a prefilter; a sound-absorbing member, through which air that has passed through the prefilter flows; and a post filter, through which air that has passed through the sound-absorbing member flows.

The present invention provides a vacuum cleaner brush head and a dust collection method. The vacuum cleaner brush head includes a brush head body, a front wiping plate, a rear wiping plate, a wiping plate driving device, and a water spraying assembly; a dust collection pipe is provided in the brush head body; the dust collection pipe has a dust collection port formed on the front side of the bottom of the brush head body; a water spraying port of the water spraying assembly is provided on the bottom of the brush head body and located between the front wiping plate and the rear wiping plate; the wiping plate driving device is transmittingly connected to the front wiping plate and the rear wiping plate, and is configured to drive the front wiping plate and the rear wiping plate to move reciprocally in opposite directions

An air flow channel switching apparatus includes a housing. A front end of the housing is provided with air inlet and outlet. An interior of the housing is provided with a blower assembly and an vacuum assembly. One sides of the blower assembly and the vacuum assembly are provided with at least one group of air duct switching assembly. The air duct switching assembly includes a mounting bracket, a pipe connector, a flexible hose, and a rotating assembly.

A suction nozzle (100) for a hand-held milling machine (200), the suction nozzle (100) including a suction connection (30) designed for connection to a dust extraction system (300), and the hand-held milling machine (200) being equipped with a depth stop (210), with the aid of which a penetration depth (ET) of a milling tool (220) of the hand-held milling machine (200) may be limited, the suction nozzle (100) having a connection area (10), via which the suction nozzle (100) is detachably fastenable, in particular detachably fastenable without tools, to the depth stop (210).

A vacuum cleaner nozzle, having a connector socket, pivotally connected to the nozzle by a joint. The connector socket has an inner tubular opening configured to receive a vacuum cleaner tube. A connector socket release mechanism, has a locking member, moveable between a first position, where it is inserted in the tubular opening of the connector socket in order to retain the vacuum cleaner tube therein, and a second position, where it is forced out of the tubular opening by a movement in the joint, in order to release the vacuum cleaner tube.

An example of a vacuum pod may include a handle, a vacuum pod body, a dust cup removably coupled to the vacuum pod body, and a fluid conduit fluidly coupled to the dust cup. The fluid conduit may include a flexible hose configured to transition between an expanded and a retracted position and a coupling configured to be removably coupled to the vacuum pod body. A first end of the flexible hose may be coupled to the vacuum pod body and a second end of the flexible hose may be coupled to the coupling. When the coupling is coupled to the vacuum pod body, the flexible hose may be in the retracted position.
