BRIEF SUMMARY
BACKGROUND
The present invention concerns a device housed in a container placed beside a water closet ("WC") or similar fixture. The device includes a rotating brush which is fed by the water pressure of the system and is mounted on a handle which can be grasped to reach and clean the internal surface of WCs and similar fixtures.
It is well known that conventional WC cleaning devices such as manual whiskers or cleaners, after they remove all toilet residues, remain impregnated therewith. The consequent presence of the residue is unhealthy and it causes unpleasant odors.
The main purpose of the present invention is to eliminate hygienic-sanitary deficiencies and to assure hygiene and health, particularly in public facilities like hospitals, schools, communities, railway stations, filling stations, cinemas, and, in general, all those structures in which many people use the bathrooms every day.
The advantages of the device according to the present invention are many and considerable: device; residue from the WC; reached with conventional means; containers of existing WC cleaning devices; and,
SUMMARY OF THE INVENTION
According to the present invention, an apparatus for cleaning the internal surfaces of a WC or similar fixture includes a brush supported in a container which is divided into separate upper and lower sections. The brush is rotatably mounted on a handle, and it is removable from the container to reach and clean the internal surfaces of a WC. An actuator is operated to release water onto the bristles of the brush. The upper section of the container encloses a water supply system for feeding warm or cold water to a flexible tube which feeds water to the brush. Also inside the upper section is a device for rolling up the flexible tube. This device allows the unrolling of the flexible tube from the device and the return of the flexible tube to its rolled up condition. The lower section of the container has a sealing door, a drain hole for discharging to a sewer any residue dripping from the brush, and a cleaning rod which protrudes into the bristles of the brush in the container to clean the bristles when the brush is rotated inside the container.
Preferably, there is a duct inside the brush handle, and an impeller which receives water from the duct to rotate the brush in response to the pressure of water received by the impeller. The water supply system feeds water to the brush to clean it further when the brush is in the lower section of the container.
Other optional features of the invention are that the container has an external sealing door, the brush is rotated at a speed of about 200-250 revolutions per minute, the flexible tube has a quick connection to the brush handle, and the upper section of the container is provided with conduits and taps for warm water and cold water.

DETAILED DESCRIPTION
The enclosed figures show a rotating, water-fed brush device according to the present invention, for the internal cleaning of WCs and similar fixtures. The device includes a container, preferably of plastic material, is divided into an upper section 1 and a lower section 2.
A brush 9 is rotated at low speed by water which moves through a duct in the brush handle 8 to an impeller 9a. The brush rotates in the range of 200-250 revolutions/minute, and it can reach and carefully clean each part of the WC. The rotary movement is represented by the arrows 9b in FIGS. 1 and 2. The brush is fed with warm or cold water by a flexible tube 7. A quick connection 6 system at the top of the brush handle 8 is shown in FIG. 1. The
