Abstract:
1. A cleaning device for cleaning substrates, the device comprising: a generally cylindrically-shaped brush mandrel having a body section with an outer surface positioned about a central axis, wherein the outer surface is interrupted by a first engagement member having a primary feature adjacent a secondary feature; and a cylindrical brush having a hollow bore formed around the brush mandrel, the hollow bore having an inner surface interrupted by a second engagement member which mates with and surrounds the first engagement member of the brush mandrel, wherein the primary feature is a first surface which flows in a direction generally perpendicular to a rotational direction of the brush mandrel around the central axis in order to prevent rotational movement of the cylindrical brush with respect to the brush mandrel, wherein the secondary feature is a second surface which flows in a direction generally perpendicular to the first surface and along the central axis, and wherein the second surface has a first portion which is closer to the central axis and a second portion which is further away from the central axis than the first portion in order to prevent axial movement of the cylindrical brush with respect to the brush mandrel, and wherein the primary feature is a channel starting at a first end and ending at a second end, and wherein the secondary feature is a curved surface at the bottom of the channel having a first curved taper at the first end of the channel and a second curved taper at the second end of the channel.
