Abstract: A squeezing device for squeezing a cleaning device having at least one pressing element, at least one counterpressing element, and at least one adjusting device. The adjusting device is configured to adjust the squeezing force and has at least one selector element and at least one shifting element. The selector element has at least a first recess and a second recess. The shifting element is at least partially received in the first recess when the selector element is in the first position and is at least partially received in the second recess when the selector element is in the second position, whereby the distance between the pressing element and the counterpressing element and thereby the squeezing force is adjustable.

Abstract: A sealing element (5) for a filter element (2) in a housing body (1) of a filtration device, preferably in a cross-flow filtration device. The sealing element (5) is of one-piece annular design and comprises a section for the sealing arrangement of the filter element (2) in the housing body (1) and a section for stop damping the filter element (2).

Abstract: A cleaning device having a handle extending along a longitudinal axis and a cleaning head. The cleaning head is in connection with the handle and is configured such that a cleaning pad is detachably fastenable to the cleaning head. The cleaning device further has a detaching device that is movably mounted to the handle and is configured to be moved along the longitudinal axis with respect to the handle from a cleaning position, in which a cleaning pad being fastened to the cleaning head remains fastened to the cleaning head, into a detaching position, in which a cleaning pad being fastened to the cleaning head is detached from the cleaning head.
