A rigid arm is attached to each end of the connecting member, with each arm supporting an end of the brush. There is a hand operable latch for releasing one of the arms to permit removal or replacement of the brush, with the hand operable latch being arranged to retain the one arm and attachment to the connecting member, with release thereof permitting removal of the arm from the connecting member and brush.
