For example, when a surface treatment system for removing spills is required, the surface treatment system can be configured to provide a wet or dry vacuum function.

Optionally, the surface treatment system comprises a plurality of interchangeable surface treatment head modules, each of which being configured for engagement with a surface to be treated.

Having a plurality of interchangeable surface treatment head modules configured for location at a distal end of the elongate surface treatment tool facilitates use of the tool for different surface treatment applications (e.g. dry vacuuming, scrubbing and/or drying of hard floors, washing carpets/furniture etc.).

Optionally, each of the plurality of interchangeable surface treatment head modules is configured to provide a different combination of surface treatment functions.

Optionally, one or more of the interchangeable surface treatment head modules comprises a suction region for sucking fluid, and optionally particles entrained therein, from a surface to be treated; optionally, wherein said fluid comprises a gas (e.g. air) and/or a liquid.

In this way, the said interchangeable surface treatment head modules is configured to provide a wet and/or dry vacuum function.

For example, such that a front edge of the movable surface treatment element faces forwards with respect to the treatment direction throughout the cyclical motion.

Optionally, one or more of the interchangeable surface treatment head modules comprising a movable surface treatment element also comprises a driving mechanism for rotating the movable surface treatment element about an axis parallel to a surface to be treated; optionally, wherein said movable surface treatment element comprises a cylindrical brush; and/or optionally, wherein the driving mechanism comprises a motor.

Such a movable surface treatment unit has been found to be particularly effective for treatment of soft surfaces such as carpets and upholstery (e.g. when dry vacuuming or cleaning of said soft surfaces).

Optionally, one or more of the interchangeable surface treatment head modules is configured to apply fluid from the fluid tank to a surface to be treated.

Optionally, the elongate surface treatment tool comprises a fluid supply path for fluid communication between said fluid tank and said one or more interchangeable surface treatment head modules configured to apply fluid to a surface.

Optionally, when the elongate surface treatment tool comprises a surface treatment head module which is not configured to apply fluid to a surface to be treated, the surface treatment tool is configured to prevent flow of fluid along the fluid supply path.

In some embodiments, the surface treatment system is configured to block the fluid supply path when the elongate surface treatment tool comprises a surface treatment head module which is not configured to apply fluid to the surface to be treated, optionally the surface treatment tool comprises a blocking mechanism (e.g. a plug or a valve) for blocking the fluid supply path.

In some embodiments, the surface treatment tool is configured to detect the functionality of the surface treatment head module forming part of the surface treatment tool and to prevent flow in the fluid supply path in the case that the surface treatment head module is not configured to apply fluid to the surface to be treated.

For example, the surface treatment tool may comprise a valve, a pump and/or fluid release mechanism configured to control flow in the fluid supply path. In some embodiments, when the elongate surface treatment tool comprises a surface treatment head module which is not configured to apply fluid to the surface to be treated, said valve is configured such that it cannot be opened (i.e. blocks flow), said pump is configured not to pump fluid in said fluid supply path, and/or said fluid release mechanism is configured not to release fluid for application to a surface to be treated.

Preventing flow of fluid in this way ensures that fluid is not applied in cleaning applications where it is not required.

Optionally, one or more of the interchangeable surface treatment head modules is configured to remove waste from a surface to be treated and to collect said waste in a waste tank.

Optionally, the elongate surface treatment tool comprises a waste removal path for fluid communication between said waste tank and said one or more interchangeable surface treatment head modules configured to remove waste from a surface.

For example, the surface treatment tool may comprise a valve and/or suction unit configured to control movement of fluid and/or waste along the waste removal path. In some embodiments, when the elongate surface treatment tool comprises a surface treatment head module which is not configured to remove waste from the surface to be treated, said valve is configured such that it cannot be opened (i.e. blocks flow of suction along said waste removal path), and/or said suction unit is configured not to operate.

Preventing flow of fluid and/or waste in this way ensures that suction is not applied in cleaning applications where it is not required.

Optionally, the plurality of interchangeable surface treatment head modules comprises one or more of: a first surface treatment head module configured for application of a fluid, surface agitation and vacuuming fluid from said surface, wherein the surface is a hard surface; a second surface treatment head module configured for surface agitation and vacuuming a surface; a third surface treatment head module configured for application of a fluid, surface agitation and vacuuming fluid from said surface, wherein the surface is a soft surface, e.g. a carpet or upholstery; a fourth surface treatment head module configured for application of fluid to a surface and surface agitation of the surface; a fifth surface treatment head module configured for application of fluid and vacuuming a surface; a sixth surface treatment head module configured for surface agitation; a seventh surface treatment head module configured for wet vacuuming a fluid from a surface; an eighth surface treatment head module configured for dry vacuuming a surface; and/or a ninth surface treatment head module configured for application of fluid to a surface.

Having a removable fluid tank module facilitates easy re-filling of the fluid tank, without having to locate the surface treatment tool under a filling station (e.g. a tap). In some embodiments, the fluid tank module may be removed and replaced with an alternative fluid tank module, for example in the case of damage, in the case where a fluid tank module with different features or attributes is required, to replace a depleted fluid tank module with a full fluid tank module, to replace a fluid tank module containing a first fluid with a fluid tank module containing a second fluid.

This facilitates ease of use and flexibility of use of the surface treatment tool.

Having interchangeable fluid tank modules allows the design of each module to be optimised for its specific application. In some embodiments, different fluid tank modules can be filled with different cleaning/treating agents depending on the intended use. This provides a quick, easy and more versatile system.

Having a removable waste tank module facilitates easy disposal of waste material and/or liquid in the waste tank, and also allows the use of different waste tank modules for different applications (e.g. a wet waste tank and a dry waste tank).

Having interchangeable waste tank modules (e.g. separate dry and liquid waste tanks) allows the design of each tank to be optimised for its specific application.

In some embodiments, the elongate surface treatment tool comprises a suction source, e.g. a suction unit for applying for sucking fluid and/or debris from the suction region to the waste tank. In some embodiments, said suction unit is configured for dry vacuuming and/or wet vacuuming.

Optionally, the handle module is configured to be coupled to a respective surface treatment head module via a releasable connector.

Having a releasable connector provides a simple means for connecting/disconnecting the surface treatment modules to the handle module.

Optionally, the surface treatment system further comprises a power source, optionally further comprising a power source module comprising the power source (e.g. a removable battery).

Having a releasable power source module simplifies charging, since it can be charged separately from the rest of the elongate surface treatment tool (e.g. in a confined space). This also facilitates replacement of the power source module with another power source module to increase operating time of the elongate cleaning tool.

In exemplary embodiments, the power source is part of another module (e.g. the handle module).

Having the power source provided as part of another module reduces the total number of modules and simplifies the assembly of the elongate cleaning tool.

Optionally, the handle module comprises an elongate spine configured to be coupled to the surface treatment head module; optionally wherein the fluid tank, the or a waste tank, the or a suction unit, and/or the or a power source are configured to be located on the handle module of the surface treatment tool.

In the illustrated embodiment, the second surface treatment head module 12b is not configured to apply fluid from a fluid tank module 8a, 8b to a surface to be treated. For example, the sixth, seventh and eighth surface treatment head modules are not configured to apply fluid from the fluid tank 22 to a surface to be treated.

The first, second, third and fourth more surface treatment head modules 12a, 12b, 12c, 12d will now be described in more detail.

With reference to figure 3a, the first surface treatment head module 12a, which is a scrubber dryer head module for use with hard surfaces, is illustrated. The scrubber dryer head module 12a is configured to apply fluid (e.g. cleaning fluid, detergent, and/or clean water) to a surface, scrub the surface and then remove fluid, together with any dirt and/or debris entrained therein, from the surface.

The scrubber dryer head module 12a has a chassis 126 having a first treatment component 128 and a second component 130. The first treatment component 128 is configured to apply fluid to a surface and scrub the surface. The second treatment component 130 is configured to remove fluid from the surface. The first component 128 is positioned forward of the second treatment component 130 in a treatment direction Dt. The first and second treatment components 128, 130 are coupled together via a bracket 132. In alternative embodiments, any configuration of components that achieves the desired functionality may be used.

The first treatment component 128 has a body 134 and a first surface treatment element 136 configured to engage a surface S to be treated. In the illustrated embodiment, the first treatment element 136 is configured for movement with respect to the body 134.

The first treatment component 128 has a driving means (not shown) such as an electric motor (e.g. digital motor) configured to drive the first surface treatment element 136 to effect treatment (e.g. agitation) of a surface to be treated. The body 134 has an annular mount 138 for location of the driving means. In alternative embodiments, the first treatment element 136 may be configured to move in unison with the body 134 (i.e. may be a static treatment element).

In the illustrated embodiment, the first surface treatment element 136 is formed of a drivable portion 136A coupled to the driving means of the body 134, and a treatment portion 136B coupled to the drivable portion 136A. In some embodiments, the entire first surface treatment element 136 is releasably coupled to the driving means of the body 134 (e.g. for cleaning and/or replacement when dirty and/or worn after use). In other embodiments, the drivable portion 136A is fixed to the driving means of the body 134 and the treatment portion 136B is releasably coupled to the drivable portion 136A (e.g. for cleaning and/or replacement when dirty and/or worn after use).

In some embodiments, an intermediate component (e.g. a support plate) is located between the treatment portion 136B and the drivable portion 136A. For example, the treatment portion 136B may be releasably coupled to the intermediate component (e.g. via hook-and-eye fasteners, magnetic coupling, snap fit coupling, resilient coupling, threaded coupling, interference fit, or any other suitable coupling) and/or the intermediate component may be releasably coupled to the drivable portion 136A (e.g. via hook-and-eye fasteners, magnetic coupling, snap fit, resilient coupling, threaded coupling, interference fit, or any other suitable coupling). In such embodiments, it may be easier to remove the treatment portion 136B from the surface treatment head module 12a by first de-coupling the intermediate component from the drivable portion 136A, and then de-coupling the treatment portion 136B from the intermediate component. In effect, the intermediate component can be considered a removable part of the treatment portion 136B, or a removable part of the drivable portion 136A.

In some embodiments, an intermediate component (e.g. a support plate) is not present and the treatment portion 136B releasably coupled directly to the drivable portion 136A (e.g. via hook-and-eye fasteners, magnetic coupling, snap fit, resilient coupling, threaded coupling, interference fit, or any other suitable coupling),In the scrubber dryer head module 12a, the driving means includes an eccentric drive mechanism configured such that the first surface treatment element 136 engages the surface S to be treated in a cyclical motion in which at least portion of the first surface treatment element 136 faces in substantially the same direction throughout the cyclical motion. For example, a front portion of the first surface treatment element 136 faces substantially forwards throughout the cyclical motion. The eccentric drive mechanism is not shown on the figures, but it will be understood to consist of an arrangement of one or more shafts and cam arrangements coupled to the driving means (e.g. located in recesses 139 of the drivable portion 136A of the first treatment element 136 below the mount 138, as illustrated in Figure 3b). For example, the drive mechanism as disclosed in patent application GB2104339.3 may be used, or any other suitable drive mechanism.

In particular, the eccentric drive mechanism of the driving means is configured to drive the first surface treatment element 136 so that each point on the first surface treatment element 136 moves along a circular path, wherein the circular paths each have a unique centre point but a common radius dimension.

In alternative embodiments, a different type of movement is provided (e.g. the first surface treatment element may rotate or reciprocate linearly).

In embodiments where the first treatment element is static with respect to the body, the surface treatment element may just be formed of the treatment portion (e.g. the treatment portion may be directly mounted to the body and the drivable portion may be omitted).

The treatment portion 136B may be a pad, brush and/or sponge (e.g. for cleaning) or any other suitable type of element (e.g. elements for alternative types of treatment such as polishing or waxing).

The first treatment component 128 includes the fluid outlet 137 which is provided proximal the front edge 140 of the first treatment component 128 (e.g. coupled to a front of the body 134). In this way, the fluid outlet 137 is configured to apply fluid to a region of the surface to be treated forward of the first surface treatment element 136 with respect to the treatment direction Dt.
