Definitions
- the present invention relates to apparatus for cleaning submerged surfaces of swimming pools, hot tubs and spas. More specifically, the present invention relates to an adaptable nozzle attachment for a swimming pool cleaner.
- Pool cleaning apparatus for passing over the surfaces of pools to remove dirt and debris and to filter the pool water.
- Such pool cleaning apparatus are typically bulky.
- Lightweight and hand-held pool cleaners are advantageous because they allow a user to easily manipulate the pool cleaner over the surfaces of a pool, spa or pond.
- Mechanical pool cleaners which utilize the flow of water drawn through the cleaner by means of a connecting flexible suction hose in communication with a filtration system pump are well known.
- a highly portable hand-held pool cleaner is powered by rechargeable batteries and includes a body and intake nozzle for suctioning pool water.
- a nozzle attachment includes a plurality of spaced brushes, which are used to dislodge dirt and debris from the pool surface, thereby allowing the pool cleaner to suction up the dislodged debris.
- the nozzle attachment can include permanently fixed protrusions on a base to prevent the suctioning effect of the pool cleaner from causing the base to be flush with the pool surfaces.
- such fixed protrusions do not roll, or may not easily slide along a surface, and can thereby impede movement of the cleaner head.
- Pool cleaners such as professional pool cleaners, clean all types and shapes of pools having conventionally known surfaces.
- swimming pool surfaces may be formed with a gunite surface, a tiie surface, or a combination thereof. Above ground pools are fitted with a vinyl iiner, the surfaces of which are usually smooth and semi-flexible.
- the material gunite is a combination of sand and cement that covers a framework of an in-ground swimming pool.
- a gunite surface is usually textured and hard.
- Tile surfaces may be either smooth or textured, and will have depressions formed between the tiles where a waterproof sealer (e.g., grout) is provided. The roughened gunite surface, and to some extent, tile surfaces can cause extreme wear to brushes and plastic parts of the cleaner head.
- each pool, hot tub, spa, or other container for retaining a volume of water that is used for recreational or aesthetic purposes may vary, it may be more desirable to use one type of nozzle attachment over another for a particular type of surface and shape of a pool.
- many professional pool cleaners or consumers having, for example, multiple recreational and/or aesthetic water containers (e.g., pool and/ hot tub) with differing surfaces have no choice but to purchase separate cleaning equipment suitable for the different types of surfaces they encounter.
- the lack of a cleaner capable of cleaning various surface types of recreational and/or aesthetic water containers can cause additional expenses in terms of purchasing and maintaining multiple cleaning devices.
- the disadvantages heretofore associated with the prior art are overcome by the present invention of an adaptable nozzle attachment for a pool cleaner.
- the nozzle is an adjustable attachment to allow a user to selectively attach either brushes and/or rollers to a lower surface of the nozzle attachment, based on the type of surface to be cleaned.
- the adjustable nozzle attachment includes a planar member having an upper surface and a lower surface. An orifice is formed through the planar member, and is adapted for coupling to a vacuum suction source. A plurality of attaching means are formed on the lower surface of the planar member.
- each attaching means is adapted to interchangeably receive a roller or a brush at a common location of the lower surface.
- each attachment means is dedicated to selectively receive either a roller or a brush.
- the user can illustratively remove a brush and install a roller (or vice versa) based on the type of surface to be cleaned.
- the attachment means are recesses into which the brushes and/or rollers are received.
- Other means of attachment include magnets, hook-and-loop fasteners, frictional or locking slide fittings, threaded members, and other mechanical fastening means known to the art.
- the configuration of the attaching means when combined with the plurality of rollers and brushes, permits a user to adjust the overall flexibility of the nozzle attachment to accommodate the type of surface being cleaned.
- the ability to interchange the rollers and brushes, and thereby adapt the flexibility of the nozzle attachment provides a more efficient and effective nozzle attachment to clean the various surfaces of a recreational and/or aesthetic water container (e.g., pond, hot tub, pool, among others).
- a recreational and/or aesthetic water container e.g., pond, hot tub, pool, among others.
- the invention also minimizes the cost to the manufacturer of a recreational and/or aesthetic water container by providing a single vacuum attachment head along with a plurality of brushes and rollers that the purchaser/user can install, based on the surface to be cleaned.
- the ability to convert the attachment of the invention is also particularly attractive to purchasers who have two or more recreational and/or aesthetic water containers (e.g., pools and/or spas), who will be able to remove the brushes and install the rollers (or vice versa) to change the flexible and performance characteristics of the vacuum cleaning/pick-up attachment.
- two or more recreational and/or aesthetic water containers e.g., pools and/or spas
- the brushes and install the rollers or vice versa

- the present invention provides various embodiments of an adaptable nozzle attachment suitable for cleaning various textured underwater surfaces.
- the nozzle attachment is suitable for cleaning a variety of swimming pool surfaces, such as flexible vinyl liners, gunite, and tile, among other textured and non-textured surfaces.
- the pool cleaner can also be used for cleaning other vessels containing water, such as spas, hot tubs, ornamental outdoor ponds, among other recreational and aesthetic water containers.
- the present invention is generally discussed in terms of a "nozzle attachment.” However, the present invention is applicable to any other nozzle head, suction head, face plate, vacuum head, or other projecting component with an opening for regulating and directing a flow of fluid while illustratively cleaning a surface of a vessel, such as a swimming pool.
- an adjustable nozzle attachment in one embodiment, includes a planar member having an upper surface and a lower surface with an orifice formed there through the upper and lower surfaces of said planar member.
- the orifice is adapted for coupling to a vacuum source, such as an underwater vacuum cleaner.
- a plurality of attaching means are formed at the lower surface of the planar member, where each attaching means is adapted to interchangeably receive at least one of a plurality of rollers and a plurality of brushes.
- the planar member is manufactured from a flexible material, such as a synthetic polymer, natural or synthetic rubber, or other suitable flexible materials.
- the flexibility of the planar member can be selectively controlled by the type and user placement of rollers and/or brushes that are coupled to the attachment means.
- rollers can be selectively interchanged and attached to the lower surface of the nozzle attachment for use with swimming pools having a gunite surface material.
- the planar member substantially retains its flexible characteristics and can follow the contours of the pool surface area being cleaned. That is, the flexible planar member will substantially assume the radius of curvature typically found in gunite pools.
- brushes may be interchangeably attached to the lower surface of the nozzle attachment for use with swimming pools having a vinyl liner.
- FIG. 1 illustrates one mode of operating a pool cleaner 10 in accordance with one embodiment of the present invention.
- the pool cleaner 10 is capable of suctioning matter, such as water and particulate solid material including debris of a relatively large size (e.g., insects, leaves, small twigs) from the surfaces to be cleaned.
- the pool cleaner 10 includes body 16, a nozzle attachment 36, a filter, and one or a plurality of discharge ports for expelling the filtered water.
- the pool cleaner 10 can be a battery-powered pool cleaner, as shown and described in commonly assigned U.S. Patent 6,797,157 to Erlich, the contents of which is incorporated by reference in its entirety.
- the pool cleaner 10 may include any vacuum source (e.g., a pump) for providing suction to remove matter from an underwater environment.
- the vacuum source e.g., body
- the vacuum source may be positioned externally from the swimming pool, such that a connecting hose is utilized between the nozzle attachment 36 and body 16.
- the pool cleaner 10 is attachable to a pole 12, which allows the user to clean the pool surfaces while standing outside the pool.
- the pool cleaner 10 includes an integral handle 14 (see FIG. 2), allowing the user immersed with the pool cleaner 10 in the pool to grasp and orient the pool cleaner 10 and so to manipulate the pool cleaner 10 over the surfaces of the pool.
- FIG. 2 depicts a side elevational view of the pool cleaner 10 illustrated in FIG. 1.
- the embodiment of the pool cleaner shown in FiG. 2 includes a body 16 that is submersible.
- the body 16 can be composed of molded plastic with an ergonomical and streamlined shape, e.g., a smooth and curvilinear surface providing low resistance in the water.
- the body 16 of the pool cleaner 10 includes a projecting handle 14.
- the handle is integrally formed from the molded plastic to allow the pool cleaner 10 to be hand-held and to be easily carried and manipulated.
- the body 16 can include hollow sections (not shown) that fill with water during immersion, so the pool cleaner 10 is not buoyant after full immersion.
- the pool cleaner 10 configured to be of essentially neutral buoyancy so that it can be manipulated underwater with relative ease, as well as in any orientation along any horizontal, vertical or curved surface that is being cleaned.
- a pole attachment member 20 extends from the body 16, allowing the extended pole 12 to be securely, but removably attached to the pool cleaner 10 for use in the first mode of operation shown in FIG. 1.
- the pole 12 can be attached to the pole attachment member 20 by any known fastening devices, such as removable screws with corresponding apertures.
- the pool attachment member 20 can include spring-loaded buttons and detents 22, such as shown in FIG. 2, or other curved surfaces for removably attaching the pole 12 in a friction fit.
- a plurality of water discharge ports or apertures 24 are present in the body 16 to allow filtered water to be returned to the pool, and for allowing water to flow into and out of the hollow portions.
- the water discharge ports 24 are symmetrically oriented to expel the filtered water in a direction generally perpendicular to the longitudinal axis 56 of the pole attachment member 20.
- the symmetrical orientation of the water discharge ports 24 helps prevent water jet pressure of the expelled water that exits from any single water expulsion port 24 from causing the pool cleaner 10 to move in an unintended direction. Accordingly, the pool cleaner 10 is easy to manipulate when in use, and responds primarily to the movement determined by the user by use of the handle 14 or the pole 12 when attached to the pole attachment member 20.
- a filter housing 26 is mounted to the fore of the body 16 for accumulating the debris suctioned into the pool cleaner 10 by the nozzle attachment 36.
- the filter housing 26 is composed of transparent plastic, allowing the user to see the amount of debris suctioned and the remaining capacity of the filter housing 26 and thereby to determine the need for emptying the accumulated debris.
- the filter housing 26 can be attached to the body 16 by a latch-and-hinge arrangement.
- the filter housing 26 accommodates at least one filter 40 for trapping undesirable matter, such as debris.
- a releasable latch 28 fits into a latch aperture 30, allowing the filter housing 26 to pivot away from the body 16 about a hinge 32 to permit emptying of debris from the filter housing 26.
- the hinge 32 permanently affixes the filter housing 26 to the body 16 in a pivoting configuration.
- the hinge can be a removable hinge, engaging a complementary hinge member (not shown) on the filter housing 26, in which the filter housing 26 is capable of being detached from the hinge 32 after being pivoted to a predetermined angle.
- the filter can advantageously be joined to a two-way sealing member that is positioned between and engages both the filter housing 26 and body 16 to form a watertight seal between them.
- an impeiler (not shown) is provided in the body 16 of the pool cleaner.
- the impeller when rotating, causes the filtered water to be drawn into the nozzle attachment, pass through the filter bag and be forced out of the water discharge ports 24.
- the filter housing 26 can be conical in shape, such that while the impeller is rotating, the conical filter housing facilitates the formation of a vortex, which draws the water through the filter housing 26 and out through the water discharge ports 24. Further, the vortex also forces the debris against the bottom portion of the filter, such that the debris is first ⁇ compacted at the bottom or downstream end of the filter, thereby allowing more debris to be retained in the filter between filter cleanings.
- the nozzle attachment 36 of the present invention includes an orifice 42 that is adapted for coupling to the filter housing 26.
- a conduit element 38 such as a hose, bellows cover, among other flexible tubular conduit elements, is coupled to the nozzle attachment 36 over the orifice 42.
- the conduit element 38 can be a semi rigid tube or the like.
- the conduit element 38 can be formed of molded polymeric material, and optionally provided with wire reinforcement.
- a first end of the conduit element 38 circumscribes and is attached over the orifice 42, while a second end of the conduit element 38 is similarly coupled over an orifice 44 formed in the filter housing 26.
- the conduit element 38 forms a watertight seal at its points of attachment to the nozzle attachment 36 and housing 26.
- water and solid material may be pumped through the orifice 42 formed in the nozzle attachment 36, through the conduit element 38, and into the filter housing 26, where the filter 40 traps the solid material, and the water discharge ports 24 expel the filtered water.
- the flexible conduit element 38 permits the pool cleaner 10 to be easily manipulated over and around curved surfaces in the poo).
- conduit element 38 is illustratively shown in FIG. 2 as a flexible hose that is relatively short in length, such that the nozzle attachment 36 is positioned proximate the body 16 of the pool cleaner 10, one skilled in the art will appreciate that longer lengths of flexible hosing may also be utilized as a conduit element 38.
- longer lengths of flexible hosing may also be utilized as a conduit element 38.
- a flexible "extension" hose serves as an extension from the body 16 to the nozzle 36 to allow the cleaning person to move the nozzle attachment 36 by hand along the difficult to clean surfaces, while the negative buoyancy of the body 16 keeps the body 16 submerged and operative at another location in the water container.
- a pole attachment may be coupled either to the nozzle attachment 36 or the end of the hose extension proximate the nozzle attachment 36, to allow a cleaning person to clean any difficult to reach surfaces (e.g., a deep end) of the aesthetic or recreational water container.
- the flexible extension hose advantageously accommodates cleaning by hand or with an extension pole for those difficult surfaces requiring extra attention.

In many applications, such as cleaning a vinyl pool surface, it may be desirable to have a stiff er brush head to decrease the flexibility of the planar member. Alternatively, when cleaning a tile surface, it may be desirable to utilize a more flexible brush in the nozzle attachment 36. It is noted that all materials of construction are selected for resistance to the chemicals commonly used in maintaining water quality, cleaning compounds, and the ultra violet rays of the sun.
- the flexibility of the axle aligners 362 may vary, depending on the surface to be cleaned by the nozzle attachment 36.
- the brushes and rollers have been shown and described in the various embodiments as being attached to the planar member of the nozzle attachment via recess formed therein, such attachment means is not to be considered as being limiting.
- the brushes and rollers can be attached by fasteners, such as clips, mating snaps, and/or other conventional fasteners known in the art.
- the present invention provides a nozzle attachment 36 that includes removable and/or interchangeable brushes and rollers.
- the user is able to adjust the flexibility of the nozzle attachment 36 by installing brushes and/or rollers producing differing stiffness characteristics in the normally flexible planar member, depending on the type of surface area (e.g., gunite, vinyl, tile, among others) to be cleaned.
- the user e.g., as a professional poo! cleaning service
