Adaptable nozzle attachment for pool cleaner

Abstract

An adjustable nozzle attachment for a pool cleaner includes a planar member having an upper surface and a lower surface with an orifice formed through the planar member adapted for coupling to a vacuum suction source. A plurality of attaching means are formed on the lower surface of the planar member, each of which is adapted to interchangeably or selectively receive at least one of a plurality of rollers and a plurality of brushes that extend from the lower surface and support the nozzle attachment during movement over a surface being cleaned. When installed, the plurality of rollers and brushes change the nozzle attachment's flexibility characteristics, thereby permitting a user to adjust the overall flexibility of the nozzle attachment, based upon the type of surface to be cleaned.

Description

FIELD OF INVENTION [0001] 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. BACKGROUND OF THE INVENTION [0002] Pool cleaning apparatus are known 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. [0003] In commonly assigned U.S. Pat. No. 6,797,157 to Erlich, a highly portable hand-held pool cleaner is powered by rechargeable batteries and includes a body and intake nozz...

AI Technical Summary

Benefits of technology

[0011] 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. Thus, 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).

[0012] 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.

Problems solved by technology

Such pool cleaning apparatus are typically bulky.

However, such fixed protrusions do not roll, or may not easily slide along a surface, and can thereby impede movement of the cleaner head.

The roughened gunite surface, and to some extent, tile surfaces can cause extreme wear to brushes and plastic parts of the cleaner head.

Thus, 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.
