A surface cleaner having a cleaning head. The cleaning head has a deck and a skirt extending from the deck such that when the skirt is placed in contact with the surface to be cleaned, a cleaning volume is defined. The cleaning head has at least one vent port and at least one vacuum port formed therein. Nozzles are mounted in the cleaning volume for movement therein when fluid under pressure is supplied thereto and sprayed therefrom. A liquid supply system supplies the fluid under pressure to the nozzles so that the surface to be cleaned is effectively scrubbed by the fluid to produce a mixture of the fluid and contaminants loosened from the surface to be cleaned. A vacuum recycling system coupled to the vacuum port(s) draws high-pressure air through the vent port(s) and over the surface being sprayed with the liquid under pressure. The mixture of fluid and contaminants is suctioned through the vacuum port(s) and filtered to separate the fluid from the contaminants. The fluid so-separated is then discharged. The fluid has a boiling point lower than the temperature and atmospheric pressure in which the cleaner is operated.
