Patents Act 1990 COMPLETE SPECIFICATION Standard Patent Applicant(s): Vax Limited Invention Title: MACHINE FOR CLEANING A SURFACE E.G. A FLOOR SURFACE The following statement is a full description of this invention, including the best method for performing it known to me/us: 2 MACHINE FOR CLEANING A SURFACE E.G. A FLOOR SURFACE a Description of Invention This invention relates to a machine for cleaning a surface, for example a floor surface.
t'q In The invention has been devised in relation to a machine for floor cleaning, particularly carpet cleaning, by application of a cleaning liquid to the floor and removal of the liquid therefrom when it has fulfilled its cleaning function.
N Machines for cleaning carpets in this manner are well known. A typical machine includes a reservoir for containing a cleaning liquid (normally water having a suitable detergent added thereto), and an arrangement for delivering the cleaning liquid to a cleaning head which is moveable over the carpet to be cleaned and distributes the liquid thereon. The machine further comprises a source of suction for extracting the cleaning liquid from the carpet and arranged to deliver such liquid, which is dirty having fulfilled its cleaning function, to a further reservoir. There are special-purpose machines for cleaning in this way, which may be of the "upright" type, having a cleaning head moveable over the carpet surface and a body extending upwardly from the cleaning head, the body being tiltable relative to the head and having a handle by which a user can manoeuvre the machine to move the cleaning head as required over the carpet which is to be cleaned. In such a machine, a motor driving an impeller to create the suction for extracting dirty cleaning liquid from the carpet may be carried by the cleaning head, the motor possibly also driving a brush bar to agitate the carpet with the cleaning liquid thereon to improve the cleaning operation, while the reservoirs for the liquid typically are carried by the body, being removable therefrom for filling the clean liquid reservoir and emptying the dirty liquid reservoir. There are also vacuum cleaners which are able to be adapted for carpet cleaning, having, in the case of a vacuum cleaner of the "canister" or "cylinder" type with a main body containing the cleaner's source of suction and means for separating and collecting dirt which has been sucked up, a specialpurpose cleaning head which can be connected at the end of a rigid, possibly telescopic extendible and contractible, wand, so as to be moveable over a carpet surface. Reservoirs for clean and dirty liquid are provided in or associated with the main body of the cleaner.

O It may be the case that carpet cleaning requires the application of a treatment a fluid to the carpet in addition to the cleaning liquid applied in normal operation of the machine. Such a treatment fluid may be an extra quantity of the normal cleaning liquid, e.g. to be applied to a particularly dirty part of the carpet prior to or in the course of the normal use of the cleaning machine thereon, or it may be c a more concentrated solution of the detergent used in the cleaning solution or some other agent e.g. a special-purpose spot remover or the like.
io Hitherto such application of other fluids to a surface being cleaned has necessitated the use of hand-held sprayers, applicator pads or the like separate (from the cleaning machine, and for floor cleaning this has usually involved the person carrying out the cleaning operation in bending to floor level or kneeling down. This is inconvenient.
It is broadly the object of the present invention to render such application of such an additional treatment fluid to a floor surface less inconvenient.
According to one aspect of the present invention, we provide a machine for cleaning a surface by application of a cleaning liquid thereto and removal of the liquid therefrom, additionally provided with a manually controllable means for applying a fluid to the surface.
The manually controllable means for applying a fluid to the surface may comprise a dispensing device, e.g. a spray nozzle, provided on a cleaning head of the machine. A control may be provided, operable by a user of the machine, to determine when the fluid is to be dispensed from the device to be applied to the surface.
Preferably the manually controllable means is manually directable, so that the fluid may be applied to a required part or region of the surface.
The manually controllable means may comprise a dispensing device which can be stored on the machine when not in use and removed therefrom to apply the fluid to any required part of the surface relative to the machine.
The dispensing device may comprise a spray nozzle or the like, and such a N:\Melourne\Cases\Patent\62000-62999\P62973.AU\Specis\P62973- VAX.doc 30/11/06 4

O nozzle may be provided at the end of an elongate dispensing element of the o type commonly referred to as a wand or lance, having a handle at or adjacent a its other end by which it may be held by a user. A flow control means may be provided at or in association with the handle, e.g. a trigger-operated valve, so that the user may control the application of fluid by the device.
1 The use of an elongate dispensing element enables the fluid to be applied to a floor surface with a degree of accuracy as to the position or region of such application, without necessitating the user's bending or kneeling.
SA reservoir for the fluid which is able to be applied by such a dispensing device 1 may be carried by the machine and connected to the dispensing device by a flexible tube. A pump may be provided for delivering the fluid from the reservoir to the dispensing device.
The fluid may be the liquid which is used by the cleaning machine in its cleaning operation, with the dispensing device connected to the reservoir provided on the machine for clean such liquid. Alternatively a further reservoir may be provided on the machine for a different liquid, e.g. a special purpose cleaning liquid or a more concentrated solution of the detergent generally used in the cleaning liquid in the machine.
The machine may be a carpet cleaning machine of the upright type, in which case an elongate dispensing element such a wand or lance may be accommodated, when not in use, in a suitable retaining formation or formations provided on the upwardly extending body of the machine. It may be easily detached from such a formation or formations and wielded by a user to apply a cleaning fluid to a carpet being cleaned, e.g. for additional spot or small area treatment.
Although mainly intended for use with, and described hereafter in relation to, a carpet cleaning machine of the upright type, the invention may also find application in relation to a machine of the canister or cylinder type. Thus, a dispensing element such a wand or lance may be held in formations on the body of such a machine which has the reservoirs and source of suction of the machine, or on a wand carrying a cleaning head of such a machine.

Further it is to be understood that although the invention is described herein in Srelation to the pre-treatment of a carpet or the like with a cleaning fluid, it may a also be applicable to use with other treatment fluids, e.g. a post-cleaning protective stain-resistant) and/or fragrancing fluid. Possibly such fluid could be in the form of a powder rather than a liquid.
1 The invention will now be described by way of example with reference to the accompanying drawing, which illustrates a carpet cleaning machine of the upright type.
SThe machine, as is generally known for machines of this type, comprises a N cleaning head part indicated generally at 10 and a body part indicated generally at 11, extending upwardly from a rearmost region of the cleaning head 10. The body 11 is connected to the cleaning head for pivoting movement about a transverse axis, and has a handle 12 at its uppermost end to enable a user to manoeuvre the machine and specifically its cleaning head over a floor surface such as a carpet which is to be cleaned. The cleaning head 10 of the machine has laterally spaced wheels 13 at its rear end, and at a forward end part has in its underside a chamber 14 facing the surface on which the machine stands.
Provision is made for the application of cleaning liquid to the surface in the vicinity of such chamber, e.g. at the front boundary thereof, and in the chamber there may be disposed one or more brush bars or other agitators for agitating a carpet being cleaned to improve the cleaning action. Provision is made for extraction by suction of the cleaning liquid from the chamber and the carpet therebeneath, the cleaning head 10 containing an electric motor and impeller to provide suction for this purpose: the motor may also drive the agitator(s).
The body 11 of the machine houses a reservoir assembly indicated generally at including a reservoir for the cleaning liquid from which it is delivered to the cleaning head, and a further reservoir for dirty such liquid extracted from a carpet being cleaned. The clean liquid may be a detergent pre-mixed with water, or there may be yet a further reservoir for the detergent alone in concentrated form, which is mixed with clean water by the machine prior to its application to a carpet. It would be appreciated that the machine incorporates suitable ducts, passages, controls, and the like, all of which are generally known in relation to carpet cleaning machines, for enabling and controlling its operation.
