ABSTRACT The invention relates to a blade-protecting device (13, 14) for cleaning units (1) being provided with a rotary cutter or blade (3) which is supported on a shaft (6) and which can be rotated by means of a motor (11). The shaft (6) is mounted in a body (8). The blade-protecting device (13, 14) comprises a hub part (13) having a diameter being smaller than the diameter or the largest dimension of the rotatable blade (3). This hub part (13) is arranged substantially coaxially with the shaft (6) adjacent the blade (3) and is freely rotatable relatively to the body (8). A number of fix, substantially radially oriented arms (14) are rigidly attached to the hub part and extend past the periphery of the blade or of the circle described by the rotating blade, said arms (14) preferably being arranged in locations spaced equiangularly around the hub part. Figure 3.
