Abstract: A steam cleaning machine has a vacuum pump seated in a recess in a top of a main support housing and a first conduit resiliently sealed in a channel leading under the recess and connecting the first conduit with the air inlet of the pump. The first conduit passes through a vacuum cover which is fitted over the top of main support housing and is attached to a dome which is resiliently sealed to a recovery tank, while a second conduit is connected to the exhaust of the pump. A third conduit is connected to a vacuum nozzle, passes through vacuum cover and is also attached to the dome which is supported by first and third conduits from the vacuum cover. An adjustable handle is pivoted at the back of main support housing.

Abstract: A steam cleaning machine wherein the clean water tank serves as a chassis for the machine. A main support housing and a recovery tank is mounted on top of the clean water tank which has an upwardly bowed bottom forming a cavity within which is mounted a spray nozzle and a vacuum nozzle. The clean water tank is mounted on wheels, an axle of which passes through the clean water tank.
