  • the collecting device is designed in the manner of a collecting container.
  • the collecting container may have a single chamber or a plurality of chambers in which the liquid is collected.
  • the free volume of the chamber or the chambers determines the storage volume of the collecting device, that is, the amount of liquid that can be received in the collecting device.

  • the catcher can be arranged as a separately manufactured element on the cover element, for example by joining techniques such as gluing, welding, snap-in and the like, giving priority to such fastening methods which provide a fluid-tight connection between the cover element and the catcher.
  • the collecting device is offset radially inwardly disposed on a facing to the cleaning roller inner wall of the cover member.
  • the collecting device is thus located directly in the flow path of the liquid, which flows along the inner wall of the cover element.
  • the collecting device is located in the circumferential direction of the cover element at that end region of the cover element which, in a fully opened state of the roller cover, represents a lowest point of the cover element displaced into the open position. This ensures that the liquid can not escape from the catcher but is trapped in an upright container.
  • the radial width of the catcher is less than the radial distance between the cleaning roller and the cover member so that the cover member can be displaced without the catcher rubbing against the cleaning roller.
  • the collecting device may have a radial width of a few millimeters, for example 5 mm to 10 mm, wherein a radial free space of preferably at least 2 mm should remain between the collecting device and the cleaning roller. te, to absorb changes in the diameter of the cleaning roller, for example due to centrifugal force-dependent deformations.

  • a capacity of the catcher of up to 30 ml is sufficient to be able to safely hold the residual liquid remaining in the roll cover after a regeneration process of the cleaning roller.
  • usually not the entire available amount of liquid of the wet cleaning device is used at one time for moistening the cleaning roller. Therefore, that portion of the liquid which does not reach a collecting tank for dirty liquid during the spin-off from the cleaning roller during the regeneration operation is usually only a very small fraction of the total liquid quantity. Therefore, if the collecting device can absorb up to 30 ml of liquid, possibly even less, for example only 20 ml or only 10 ml, dripping is reliably prevented.
  • the collecting device has an opening which precedes the storage volume in an opening direction of the roll cover.
  • the catching device which is preferably designed as a collecting container, thus has an opening which, during the displacement of the cover element, also moves in such a way that the opening in the open position of the cover element (relative to a vertical) is arranged above the storage volume. This ensures that the liquid can not leave the catcher.
  • the opening can again reach below a level of the storage volume, so that liquid ability to escape from the collecting device on the inner wall of the cover member.

It is thus not necessary to provide further remplisstechniksleit Surpriseen on the inner wall of the cover member, which direct the liquid to the collecting device. Rather, the fluid located on the inner wall of gravity always follows in an opening of the opening portion of the roller cover in the catcher. Dropping of liquid from the roll cover is thus effectively prevented over the entire axial length of the roll cover.

  • the proposed size of the angle section of 30 ° to 90 ° is particularly suitable for cover elements which can be displaced by approximately 180 ° in order to selectively open or close the opening region.
  • the liquid flows at standstill of the cleaning roller to the lowest point within the roller cover.
  • the collecting device should preferably not be arranged exactly there, since liquid dripping vertically downwards from the cleaning roller drips onto an outer wall of the collecting device and from there can then reach a freshly cleaned surface during a subsequent opening of the opening region.
  • the catching device covers only 30 ° to 90 ° of a peripheral portion of the cover element, there is a sufficient angle section which remains free for the dripping off of liquid next to the catching device. It is particularly advisable that the collecting device is not arranged vertically under the cleaning roller when the roller cover is closed, but is offset by an angle, for example relative to an angle between a vertical direction and a plane, into which the opening of the collecting device is arranged, preferably at least 30 °.
  • the wet cleaning device has at least one catching device which is arranged on the cover element with respect to an axial direction.

This makes it possible to remove the collecting device from the wet cleaning device, so that the collecting device can be easily cleaned by a user of the wet cleaning device, in particular to remove dirt deposits from time to time.
  • an inner wall of the cover element has a feed ramp which is inclined relative to a horizontal and extends, in particular, from a center of an axial longitudinal extent of the cover element to the end catcher, which is designed such that liquid located inside the roll cover is guided in a subsequent displacement of the cover member in an opening direction of gravity in the end-side collecting device.
