Abstract: A portable extractor apparatus is shown which includes a wheel mounted base having a solution tank for dispensing and recovering cleaning solution. A cleaning wand is connected to the solution tank and has a head which contacts the surface to the cleaned for dispensing and recovering cleaning solution. A fluid pump circulates cleaning solution in a path between the solution tank and the cleaning head. A vacuum motor provides a vacuum source for the cleaning head for suctioning the surface being cleaned and has an exhaust fan for exhausting excess heat created by the operation of the vacuum motor. A fluid operated heat exchanger is mounted in the vicinity of the vacuum motor. The heat exchanger is plumbed in the circulation path of the cleaning fluid, whereby excess heat generated by the vacuum motor is transferred to the cleaning fluid being applied from the cleaning head onto the surface to be cleaned. The cleaning head can also be integrally mounted on the wheel mounted base.

Abstract: An tandem tubing assembly for a cleaning machine is disclosed comprising a flexible first tubing having a first diameter and configured as a flexible hose having a helical frame, a relaxed length and an extended length; a flexible second tubing having a second diameter substantially smaller than the first diameter of the first tubing and configured as a helical coil having a relaxed length and an extended length, wherein the second tubing, in its coiled form, is disposed inside the first tubing, and respective ends of the first tubing and the second tubing are coupled together such that the first and second tubings flex together and extend or contract together between the extended and the relaxed lengths.

Abstract: There is disclosed a portable fan for drying floor surfaces, comprising a fan casing and a receiver attached to a rearward outside surface of the fan casing for receiving and storing first and second parallel, telescoping struts of a collapsible handle within first and second parallel wells disposed therewithin; and a collapsible handle having first and second parallel, telescoping struts stored in the first and second wells of the receiver and extendable by pulling upon the collapsible handle or upon release of a latch operated by a button in a handle grip connected between upper ends of the first and second struts of the collapsible handle.
