Claim 17:
18. An offline brush conditioning system configured to condition a plurality of brushes, the offline brush conditioning system comprising:
a first brush holding device configured to hold a first brush in contact with a first conditioning surface;
a second brush holding device configured to hold a second brush in contact with a second conditioning surface
a barrier configured to isolate the first brush from the second brush to mitigate cross-contamination during a conditioning process;
a conduit configured to receive a chemical from a source for delivery of the chemical to a manifold, wherein the manifold is configured to deliver, during the conditioning process, the chemical to (1) the first brush or the first conditioning surface and (2) second brush or the second conditioning surface; and
a controller operably coupled to a plurality of sensors and configured to:
adjust the conditioning process based on feedback data from a first sensor of the plurality of sensors for one or more outflow conduits, each of the one or more outflow conduits corresponding to a section of each of the first and second brushes and torque output of a motor from a second sensor of the plurality of sensors,
determine when the conditioning process is finished for each of the first brush and second brush using the feedback data from each of the first and second sensors, and
verify a concentricity of each of the first brush and the second brush using a measurement from the second sensor reflecting the torque output.
