Abstract (en)
[origin: EP2245974A2] The operation method involves rotating the brush roller (16) in a normal operational direction during operation, and rotating the brush roller in a reverse direction opposite to the normal operational direction of rotation when the brush roller is detected to be jammed. The jamming is detected when the current consumption of motor exceeds a predetermined threshold. The brush roller is rotated in the reverse direction by a predetermined angle upon occurrence of jamming. An independent claim is included for an attachment device.
