  • Patent number: 7171722
    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.

  • Patent number: 6449799
    Abstract: A vacuum system is described in which a hollow vacuum housing is provided with an intake plenum leading from an open bottom housing end of the housing to a vacuum line connector. A vacuum pump is attached to the vacuum line to produce suction through the intake plenum. A hot air housing is situated within the hollow vacuum housing and includes a hot air discharge plenum. The hot air discharge plenum is defined by a wall within the intake plenum, leading from an open bottom end that is substantially circumscribed by the intake plenum. A hot air blower on the hot air housing moves hot air downwardly. The hot air moves against the surface being cleaned or dried and is subsequently drawn back upwardly through the intake plenum. At least one and preferably two compressed injection air discharge lines are positioned within the hot air housing.
