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 ).
