A computer pointer is disclosed comprised of a housing having an aperture and a ball rollably mounted within the housing so that a portion of the ball is accessible through the aperture in the housing so that force can be exerted on the ball through the aperture to induce the ball to rotate within the housing. The pointer is further comprised of at least one rotating position member having an outer surface, the at least one rotating position member being mounted within the housing and frictionally engaged on a first side with the ball so that rolling motion of the ball results in corresponding rotation of the at least one rotating position member. Further, the computer pointer is comprised of a cleaning member mounted within the housing so as to be positioned adjacent a second side of the at least one rotating position member so that debris that is adhering to the outer surface of the at least one rotating position member is dislodged from the outer surface of the at least one rotating position member as the at least one rotating position member rotates in response to the rolling motion of the ball. In addition, a method of using a computer mouse is disclosed including the acts of inducing a ball within a housing to move resulting in the rotation of at least one rotating position member thereby causing a cleaning member adjacent to the at least one rotating position member to dislodge debris that is adhering to the outer surface of the at least one rotating position member.
