Floor or other large surface drying apparatus characterized by efficient placement and use within the apparatus of both a vacuum pump and a water pump preferably powered by one prime mover geared to drive both pumps at different speeds. Vacuum produced by the vacuum pump entrains an air/water mixture and directs said mixture into a plenum chamber disposed in the lowermost portion of the apparatus in order to reduce lift height to a minimum, water being separated from the mixture in the plenum chamber and by means of the water pump, discharged from the apparatus to a remote point through a discharge hose.
