To remove and also attach the cloth holder no additional intervention is required. When the operation button the Base body on the side facing away from the towel holder at least partially surmounted, it is particularly easy to reach and very easy to use.

The dirt container can be removable. For this purpose, the dirt container can be guided in a drawer-like manner in the base body or be lockable in the base body from the upper side, which faces away from the floor to be cleaned. In this case, the dirt container can be removed particularly easily from the cleaning device. To empty the dirt container, the bottom of the dirt container can be designed to be foldable. In this case, the bottom is preferably connected via a film hinge to the dirt container housing for ease of manufacture and is sealed dust-tight by a locking device. By loosening the locking device, the floor opens automatically and releases a very large opening through which the dirt can be removed from the dirt container very easily. The latching device also serves as a locking means to fix the dirt container in the body. To improve the tightness of the soil at the edge of a survey that engages in the closed state in a congruent shaped recess of the housing. The bottom of the dirt container further has ribs, so that the soil is not deformed and always close tight.

The dirt container may comprise a lid which at least partially projects beyond the brush roller. In this case, the lid may be integrally or hingedly connected to the dirt container. In this case, the dirt container is always removed by removing the lid up from the body. Since the lid protrudes beyond the brush roller, it is at least partially released after removal of the lid, which is particularly advantageous if it is to be cleaned.

The brush roller may be displaceable in the axial direction spring-loaded and removable. The brush roller has recesses on both end faces, into which pins for storage engage, which are arranged on the base body. To remove the brush roller is moved axially against the spring. If the pin is exposed on one end of the pen, the brush roller can be tilted out. When the lid engages over the brush roller, the brush roller can be removed after removing the lid. As a result, the brush roll can be removed with care even when standing on the floor cleaning device to clean or replace them.

The brush roller may have a disc-shaped projection. The projection is preferably arranged in the region of the end face which lies opposite the spring-loaded end face. The projection serves as a grip element and facilitates the removal of the brush roller. The radial extension of the projection is less than or equal to the radial extent of the bristles of the brush roller.
