Abstract: Rotary device from removing weeds from joints in a paved area, comprising an elongate frame (22) which is provided with a handle (23), a drive unit (24) mounted on the frame (22), a brush element (25) which is connected to the drive unit (24) in such a manner that it can be driven in rotation about an axis of rotation which extends substantially in a direction which is transverse with respect to the frame (22), and a guide wheel (28) coupled to the frame (22), the guide wheel (28) and the brush element (25) being provided on either side of the bottom end of the frame (22). The distance (x) between the guide wheel (28) and a centre axis of the frame (22) is at least double the distance (y) between the brush element (25) and the centre axis of the frame (22).
