Well there's always the washing machine. Delicates cycle. Line dry.
Seriously, I would remove the brush, use the crevice tool, and vacuum. Then if you want it to look nice use a fine quality brush like for shoe polishing, or the vacuum brush attachment, and everyone's favorite long smooth strokes to finish it off.
