ABSTRACT:
In a carpet cleaning machine with a machine housing (1), two containers (4,5) for fresh and used cleaning liquid respectively and flexible tubing (2,3) connecting the machine housing (1) to at least one liquid ejection nozzle (not shown) and a suction mouthpiece (not shown), each of the two containers (4,5) is removably supported in a space (14) above a substantially horizontal portion (7) of said housing (1) and close to a substantially vertical partition portion (8) of said housing (1), each container preferably being supported by plugs (11) extending outwards and upwards from each side of the partition portion (8) and cooperating with sockets (12) recessed into the sides (10) of the containers adapted to face the partition portion (8). Fluid communication between the machine housing (1) and the containers (4,5) may be established by said plugs (11) being tubular and cooperating with openings (13) in the inner ends of the recessed sockets (12) and/or by means of a valve-cum-connector (not shown) in the bottom of the container cooperating with an upwardly extending connector (15) on the base portion (7). This arrangement makes it easy to remove and replace each container (4,5) independently of the other container (4,5), and in the preferred embodiment shown makes the assembly comprising the machine housing (1) and the container (4,5) easy to handle and manoeuvre. A wheeled carriage (6) provides the requisite mobility.
