A cleaning device comprises a surface interaction layer (ML), a cleaning fluid supply (CFF) provided with a cleaning fluid channel (CFC) at the surface interaction layer (ML) for supplying a cleaning fluid to a surface (F) through the surface interaction layer (ML) being in contact with the surface (F), and a dirty fluid drain (DFD) having a dirty fluid channel (DFC) at the surface interaction layer (ML) for draining, by means of underpressure, dirty water from the surface (F) through the surface interaction layer (ML) being in contact with the surface (F).

Cleaning device

The present invention relates to a nozzle arrangement () of a cleaning device () for cleaning a surface (), comprising: &#x2014;a nozzle housing (); &#x2014;a rotating brush () that is rotatable about a brush axis () and comprises a substantially cylindrical core element () with flexible brush elements () that are arranged on a circumferential surface () of the core element (), wherein said brush elements () are configured to contact the surface to be cleaned () and pick up dirt and liquid particles () from the surface to be cleaned () during a rotation of the rotating brush (); &#x2014;a drive for driving the rotating brush (); &#x2014;a liquid supplying arrangement () for supplying a cleansing liquid () to the rotating brush (); &#x2014;a wiping element () for wiping dirt and liquid particles () across or off the surface to be cleaned (), wherein said wiping element () extends along a longitudinal direction (), which is arranged substantially parallel to the brush axis (), and wherein said wiping element () is arranged on a first longitudinal side () of the rotating brush () where the brush elements () enter the nozzle housing () during the rotation of the rotating brush (); and&#x2014;at least one side sealing element () for sealing a lateral side () of the nozzle housing (), wherein the at least one side sealing element () is spaced apart from a transverse side () of the core element () that is transverse to the circumferential surface () of the core element (), such that a gap () is defined between said transverse side () of the core element () and the at least one side sealing element (); wherein the liquid supplying arrangement () is configured to also supply cleaning liquid () to said gap ().

Nozzle arrangement of a cleaning device for cleaning a surface

A liquid containing system for a floor cleaning device, the liquid containing system comprising an outlet having a plurality of openings (H) to allow a liquid (W) to be extracted by means of capillary force when a mopping substrate, e.g. a cloth (C), is mounted against the plurality of openings (H), after filling the liquid containing system being substantially closed but for the plurality of openings (H).

Floor cleaning device

A nozzle () for a floor cleaning device, suitable for both wet and dry cleaning, the nozzle comprising an airflow inlet () at a front end of the nozzle, and a detachable cleaning device () that, if mounted on the nozzle (), lifts a rear end of the nozzle.

Surface cleaning device, comprising a cloth (C) placed on a porous material (PM), a reservoir (R) for collecting liquid absorbed by the cloth (C), and an arrangement (P) for applying under-pressure in the reservoir (R) so as to transfer liquid from the cloth (C) into the reservoir (R). A pore size of the porous material (PM) is between 1 &#x3bc;m and 50 &#x3bc;m.

Surface cleaning device

The present invention relates to a cleaning device for cleaning a surface (), comprising: &#x2014;a brush () rotatable about a brush axis (), said brush () being provided with flexible brush elements () that are substantially uniformly distributed over the periphery of the brush (), wherein the brush () is at least partly surrounded by a nozzle housing () and protrudes at least partially from a bottom side () of said nozzle housing (), which, during use of the device (), faces the surface to be cleaned (), wherein the brush elements (), during the rotation of the brush (), substantially form a sealing with the housing () at a first position () where the brush elements () leave the housing () during the rotation of the brush (), and contact the surface to be cleaned () during the rotation of the brush () at a second position () for picking up dirt particles () and liquid () from said surface (), thereby defining a suction area () in a space between the brush (), said housing () and said surface to be cleaned () which is at least partly sealed at said first and second positions (), &#x2014;a single squeegee element () which is spaced apart from the brush () and attached to the bottom side () of the nozzle housing () on a side of the brush (), where the brush elements () enter the housing () during the rotation of the brush (), wherein said squeegee element () is adapted for pushing or wiping dirt particles and liquid across or off the surface to be cleaned () during movement of the cleaning device (), thereby defining a suction inlet () between the squeegee element () and the brush ()that opens into the suction area (), &#x2014;a drive means for driving the brush () in rotation, and &#x2014;a vacuum aggregate ()which is arranged at a suction outlet ()of the suction area () for generating an under-pressure in said suction area () for ingesting dirt particles () and liquid () from the suction inlet ().
