1. A cleaning device comprising:
a control shaft;
a first cleaning section comprising wipers axially offset from each other, each of the wipers extending at least partially circumferentially about a first length of a core member to form a respective wiper width that is orthogonal to the first length of the core member, the respective wiper width being greater than a respective wiper longitudinal length that is parallel to the first length of the core member; and
a second cleaning section comprising fins, each of the fins extending longitudinally along a second length of the core member to form a respective fin longitudinal length that is parallel to the second length of the core member, the respective fin longitudinal length being greater than a respective fin width that is orthogonal to the second length of the core member, wherein the first length of the core member and the second length of the core member define a lumen extending at least partially through the first cleaning section and the second cleaning section, the second cleaning section having ports providing fluid communication between the lumen and a space outside the cleaning device.
