Abstract

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).

First claim

The invention claimed is:

1. A cleaning device, comprising: a cleaning fluid supply provided with a cleaning fluid channel for supplying a cleaning fluid to a surface;
a dirty fluid drain provided with a dirty fluid channel for draining a dirty fluid from the surface; and
a single fluid container comprising a first end and a second end, wherein, in a first orientation mounted in the cleaning device, the second end is located at a bottom position to supply the cleaning fluid from the second end of the single fluid container and to collect the dirty fluid at the first end of the single fluid container, wherein the single fluid container comprises a first section for the cleaning fluid, a second section, adjacent to the first section, for the dirty fluid, and a movable piston between the first section and the second section,
wherein after both the cleaning fluid and the dirty fluid are poured out of the single fluid container, the cleaning device is arranged in a second orientation for allowing the single fluid container to be mounted into the cleaning device in an upside-down-arrangement, wherein in the upside-down arrangement the first end of the single fluid container is located at the bottom position and the second end of the single fluid container is located at a top position.

2. A vacuum cleaner provided with the cleaning device as claimed in claim 1 .

3. The cleaning device of claim 1 , whereby, in the second orientation, the single fluid container is arranged for supplying the cleaning fluid from the first end of the single fluid container and for receiving the dirty fluid at the second end of the single fluid container.
