Abstract: A surface cleaning apparatus includes an upper portion having a handle and a suction motor and a surface cleaning head pivotably connected to the upper portion. The surface cleaning head includes a vacuum inlet fluidly coupled to the suction motor and an air-agitation blower assembly. The air-agitation blower assembly includes at least one air-agitation blower and at least one discharge nozzle. The least one air-agitation blower is configured to generate a pressurize air flow and includes an air pump and an air-agitation motor drivingly connected to the air pump, the air-agitation motor being independent from the suction motor. The at least one discharge nozzle is fluidly coupled to the air pump and configured to discharge the pressurized air flow to form an air-blast agitation flow.

Abstract: A thermal therapy device for applying temperature controlled therapy to a therapy site on a mammalian body, comprising: a therapy pad for applying a selected therapy temperature to the therapy site; a recirculating fluid loop comprising a fluid channel defined by the therapy pad; a pump for circulating fluid through the recirculating fluid loop; a thermal reservoir; a heat exchanger coupling the thermal reservoir with the recirculating fluid loop; and a control mechanism coupled to the heat exchanger for enabling adjustable control of therapy temperature. The heat exchanger selectively mixes fluid recirculating in the fluid loop with fluid from the thermal reservoir in an adjustable mixing ratio to achieve the selected therapy temperature at the therapy site.
