Fig. 2A illustrates a schematic, side view of a wheelchair 20 arranged in a cleaning device 2 according to the invention arranged in a close distance D2 to a wall 32. The cleaning device 2 is arranged on a floor 30 and comprises a first rotatably mounted brush 36 and a second rotatably mounted brush 36' configured to clean the wheel 18 of the wheelchair 20. The side structure of the cleaning device 2 has been removed in order to see the inside structure of the box portion 12. The cleaning device 2 comprises a first rotatably mounted roller member 34 engaging the first rotatably mounted brush 36 and a second rotatably mounted roller member 34' engaging the second rotatably mounted brush 36'. Hereby, the rotatably mounted roller members 34, 34' causes the rotatably mounted brushes 36, 36' to rotate when the wheel 18 is rotated in order to rotate the rotatably mounted roller members 34, 34'.
Accordingly, the cleaning device is manually driven and the wheelchair user can clean the wheels 18 simply by arranging the wheels 18 in the receiving groove of the cleaning device 2 and rotating the wheels 18. Fig. 2B illustrates a cleaning brush 36 engaging with a roller member 34 of a cleaning device according to an embodiment of the invention. The roller member 34 is cylindrical and has a slightly larger diameter than the cylindrical portion of the cleaning brush 36. The cleaning bush 36 has a cylindrical shape, however, a cleaning structure 42 formed as an indentation/recess is provided in the cleaning bush 36. The cleaning structure 42 is configured to facilitate the cleaning operation of a wheel arranged in the cleaning structure 42 (see Fig. 2D).
A shaft 38 connects the cleaning brush 36 and a first gear engaging a second gear 40' that is mechanically connected to the roller member 34 through a second shaft 38'. The shafts 38, 38' extend parallel to each other and the cleaning brush 36 will rotate upon rotation of the roller member 34. Accordingly, the cleaning device is manually driven and is operated by rotating the wheel engaging roller member 34, which will cause the cleaning brush 36 to rotate and hereby clean the rotating wheel arranged in the cleaning structure 42 as shown in Fig. 2D.
Fig. 2C illustrates a schematic, cross-sectional view of a cleaning brush 36 of a cleaning device according to an embodiment of the invention. The cleaning brush 36 comprises a plurality of radially extending hairs 44. Alternatively, the cleaning brush 36 may comprise a plurality of radially extending bristles.

As it can be seen in Fig. 2D illustrating a wheel 18 arranged in the cleaning structure of the cleaning brush 36 shown in Fig. 2C, the U-shaped cleaning structure fits the outer geometry of the wheel 18 arranged in the cleaning structure of the cleaning brush 36.
Fig. 3A illustrates a moveably arranged locking member 45 arranged in a nonlocking configuration between a roller member 34 and an adjacent cleaning brush 36 of a cleaning device according to an embodiment of the invention. The locking member 45 is basically wedge-shaped and comprises a pointed portion fitting the shape of the adjacent portions of the roller member 34 and the cleaning brush 36,
When the roller member 34 is rotated clockwise as illustrated by the rotational direction arrow 46', the cleaning brush 36 rotates in the opposite direction (anticlockwise) as indicated by the rotational direction arrow 46, because the roller member 34 and the cleaning brush 36 engage (e.g. by means of gears as illustrated in Fig. 2B) Fig. 3B illustrates the locking member 45 shown in Fig. 3A arranged in a locking configuration between the roller member 34 and the adjacent brush 36 shown in Fig. 3A. The shape of the locking member 45 fits the shape of the adjacent portions of the roiler member 34 and the cleaning brush 36. Accordingly, the locking member 45 prevents rotation of the roiler member 34. This means that the locking member 45 can be used to prevent the wheelchair wheels from driving rotating structures 34, 6 in a non-desired direction. Therefore, the cleaning device 2 can be "locked" by means of the locking member 45. In Fig. 3B, the roiler member 34 is rotated anticlockwise as illustrated by the rotational direction arrow 46'. The cleaning brush 36, however, rotates in the opposite direction (clockwise) as indicated by the rotational direction arrow 46, because the roller member 34 and the cleaning brush 36 engages. Fig. 3C illustrates a schematic, perspective side view of a cleaning device 2 according to an embodiment of the invention. The cleaning device 2 comprises two ramps each provided with a guiding recess 8, 8' connected to receiving grooves provided in the upper surface of two adjacent box portions. Wheels 18, 18' are arranged in the receiving grooves provided with closing structures 48, 48' sur- rounding the wheels 18, 18'. A drawer 50 having a knob 52 for opening the drawer 50 is slidably mounted in the box portion of the cleaning device 2. The drawer 50 is configured to collect the dirt from the wheels 18, 18' during the cleaning operation. The closing structures 48, 48' prevent dirt from leaving the receiving grooves.
