Each of the wet and dry cleaning mechanisms includes a wiping module that includes a vertical plate, a feeder reel, a retriever reel, direction-changing rollers and a pushing roller. The wiping module of the wet cleaning mechanism includes a sprayer mechanism adapted for spraying cleaning liquid onto a portion of the clean-room wiper on the pushing roller.
