The present invention relates to the field of floor treatment machines which collect water or other liquids from floor surfaces, such as carpet cleaning machines, wet vacuum machines and floor scrubbing machines. The invention provides a floor treatment machine comprising a body portion comprising a collection reservoir, the body portion being provided with wheel means permitting travel of the machine over a floor surface and means for withdrawing soiled liquid from the floor surface and discharging the liquid into the collection reservoir, wherein the body portion comprises an upstanding sidewall portion which defines a body portion enclosure and wherein the collection reservoir is configured and arranged to nest within the enclosure at an upper region thereof. In one aspect the invention is characterised in that a collection reservoir drain conduit is provided which extends from the collection reservoir and through the enclosure sidewall portion to an exterior of the body portion so as to permit draining of the collection reservoir while nested in the clean reservoir. In another aspect the invention is characterised in that the outside dimensions of the collection reservoir match the internal dimensions of an upper region of the enclosure so that an intimate sliding fit is made when the collection reservoir nests in the enclosure upper region. In yet another aspect the invention is characterised in that the enclosure sidewall portion is formed with at least one slot which slot extends generally vertically down from an upper rim portion of the sidewall portion, the slot being open at a rim end thereof and terminating at a lower end region thereof, and wherein a collection reservoir drain conduit or a collection reservoir inlet conduit extends from the collection reservoir through the enclosure sidewall portion to an exterior of the body portion, said slot being of a width to permit one or other of the inlet or drain conduit to be accommodated in the slot when the collection reservoir is nested in the enclosure, the slot further permitting removal of the collection reservoir and associated conduit by lifting of the collection reservoir from the enclosure. |
