The present invention relates to a device for producing high-strength COpellets from COsnow, in particular, for a cleaning device for blasting surfaces to be treated with a mixed-flow consisting of a compressed gas and COpellets, including a main compressing device for compressing COsnow for forming COpellets, further including a pre-compressing device for pre-compressing COsnow produced by expanding liquid CO, wherein the pre-compressing device is in the form of a fluid-mechanical pre-compressing device, wherein the pre-compressing device includes an expansion device for producing COsnow from liquid or gaseous COand a pre-compression chamber for receiving and pre-compressing the produced COsnow and wherein the expansion device and the pre-compression chamber are connected to one another in fluidic manner.

The invention relates to a dirt-collecting device for a floor-cleaning machine, for picking up a liquid from a floor surface which is to be cleaned, having a carrier and at least one wiping member for wiping the floor surface, the carrier and the at least one wiping member bounding a suction channel which opens out into a suction mouth and of which the free cross-sectional area, through which a suction stream can pass, decreases, at least in one channel portion, in a direction away from the suction mouth. In order to produce such a dirt-collecting device in a more cost-effective manner, it is proposed according to the invention that the suction channel has disposed in it at least one channel-narrowing member, which is produced separately from the carrier. The invention also relates to a floor-cleaning machine having such a dirt-collecting device.

The invention relates to a cleaning tool for a cleaning device, the cleaning tool being subject to wear during operation. In order to make it easier to identify wear, the invention proposes that the cleaning tool comprise a sensor device with a sensor element which has a physical characteristic variable which changes as a function of the degree of wear of the cleaning tool. The invention also proposes a cleaning device having such a cleaning tool, the cleaning device having a detector device which is coupled to the sensor device for the purpose of sensing the change in the physical characteristic variable of the sensor element, and having an indicator device which is connected to the detector device.
