ABSTRACT:
An improvement is disclosed in an apparatus of the type employed for cleaning textile coverings, especially rugs and carpeting where the apparatus is provided with at least one spray jet connected to a supply of cleaning fluid and a suction jet is connected to a dirt-laden fluid receptacle. Apparatuses of this type have at least one suction turbine connected to and actuated by a motor where the suction turbine has a suction pipe in fluid communication with a receptacle for dirt-laden fluid typically dirty water. According to the invention, the receptacle for the dirt-laden fluid is divided into a plurality of interconnecting vacuum chambers by use of vertically disposed partitions, each of which vacuum chambers is in fluid communication with a common sump disposed therebeneath. The partitions extend vertically over most of the height of the chambers. Each of the vacuum chambers is in fluid communication with its own suction turbine via a suction pipe entering the vacuum chamber. The suction pipe, in turn, is in fluid communication with a suction jet. A discharge pipe is provided for discharge of dirt-laden fluid in the common sump.
