ABSTRACT:
A vacuum cleaning and/or drying systems having heaters which provide drying air to aid in drying or combined cleaning and drying. The system is particularly adapted and beneficial for use on carpets, but can also be used to clean other surfaces such as smooth floors or upholstery. The heaters are on a portable cleaning unit used within the room being cleaned. A support unit is preferably provided outside the room or building to generate vacuum and remove moisture from the room. The support unit is typically mounted on a vehicle and can provide compressed air or other gases and cleaning fluids. Compressed air can be used to agitate and facilitate both cleaning and drying. Compressed air can also be used to apply one or more additives, such as deodorizers and fragrances. The portable unit can also be used for drying flooded carpets and the like.
