Abstract: A cleaning brush comprises a brush body rotatably mounted on and biased axially towards a brush holder by a compression spring, a post non-rotatable on the brush body and projecting axially towards the brush holder, a sleeve mounted on the posts for rotation relative thereto and non-rotatable relative to the brush holder, and an actuating lever for displacing the sleeve axially away from the brush holder. The post has a circumferentially extending slot engaged by a pair of opposed inwardly projecting pins of the sleeve to provide a camming arrangement such that operation of the lever to move the sleeve axially away from the brush holder causes rotation of the brush body. The brush body is rotatable through 180.degree. from one brushing position to another brushing position.
